• ESXi hosts are disconnected from the vCenter (5.5)

  Hi all

  We have a little problem with our vCenter.

  We have two hosts that are connected to the vCenter, unfortunately, they are listed as disconnected.

  It seems that the problem are the SSL certificates on ESXi hosts that are no longer valid.

  If I replace the old certificates with new ones, that I have to restart the ESXi host, am I right?

  If so, that's the problem.

  We do not use any what automatic vMotion and as long as the hosts are not connected to the vCenter I can't manually, move right?

  Is it possible to connect hosts to vCenter without SSL?

  Sorry for my bad English, I'm not a native speaker.

  See you soon,.

  You need to replace the ESXi host SSL certificates.

  See the Docs for the replacement of ESXi Cert below.

  ttp://www.BlueBox-Web.com/2013/04/18/replace-ESXi-certificate/

  Documentation Centre of vSphere 5.5

  I had regenerate the ESXi 5.5 SSL certificates, which I did without any stop to virtual machines.

  Certificate replacement process can change based on the esxi version.

  According to the Doc, vSphere 6.0 Documentation Centre ESXi6 host must be rebooted to replace certificates.

  Anyway, in current state disconnected, you can try to regenerate the self signed SSL certs, restart management agents and try to reconnect host in vCenter.

  Thank you

• ESXi disconnects from the vCenter

  Hello VMware,

  I have some problems with ESXi 4.1.0 (Build 260247) disconnect vCenter. I am currently evaluating Vmware View. I have no problem connecting to an ESX host to vcenter. When connecting vCenter ESXi host host will connect for about a minute and then disconnect. VCenter, Active Directory, DNS, DHCP, and ESXi host is all on the same network without any firewall between the two.

  I have an I tried by using the knowledge base article titled "Diagnose an ESX Server that is offline or does not respond in VirtualCenter" without success. I can connect the ESXi host with ssh and ping various servers on the network using dns and ip addresses.

  Is attached a copy of the message, pass and vxpa journal of the ESXi host.

  Any help would be greatly appreciated .

  Since the log files, it seems that you use vServers 4.0.

  Section for VMware VirtualCenter Agent, pid = 56646, version 4.0.0 build = build-208111 =, = exit option

  The host ESX (i) 4.1 require vCenter Server 4.1, this is why you must upgrade to vCenter Server to make it work.

• Windows Media Player 12 will not play mp4, mp3, wmv files through IIS hosted local site when the PC is disconnected from the Internet

  I have an IIS Web site 6.1 on local 32-bit Windows 7 machine that serves HTML and MP4 videos via Internet Explorer on the local computer.  An internet connection is not necessary because it is all local storage and local accommodations through IIS.  IIS is configured to serve the MP4 videos in the form of downloadable files, don't not streaming somehow.  I have the right MIME type ".mp4" with the installation of "video/mp4" in the IIS server, so I don't think that's the problem.

  When the machine is connected to the internet, by clicking on a video link MP4 in any HTML page served by the local IIS server results in Windows Media Player opening and playing the video in its own window.  However, when the Ethernet cable is unplugged, by clicking on the same results of video link MP4 in Windows Media Player by opening its own window, and then display this error message:

  Windows Media Player cannot play the file.  If the file is on the Internet, connect to the Internet.  If the file is on a removable storage card, insert the storage card.

  It's almost as if Windows Media Player has a bug and since it accesses this media file via a URL, but the machine is not connected to a network, he thinks that this file is unplayable.

  When the Ethernet cable is disconnected, the local IIS server is still all the HTML code and ActiveX content except for media files.  I also tried to access MP3 and WMV files via the IIS server to see if Windows Media Player will open those when the computer is disconnected from the Internet.  These caused also Windows Media Player files display the same error message.

  I tried the VLC (VideoLAN) Player after changing the property file in VLC of WMP for .mp4 files extension.  With VLC installed and the extension changed to VLS property, I can download/open the MP4 video using the link in the web page served by IIS all when they are disconnected from the internet.  The only thing I can't do is get VLC player to open and play the video simply by clicking on the link in Internet Explore web pages served by the local IIS server.

  I would like to make use of Internet Explorer and Windows Media Player with this IIS server that serves the MP4 videos rather than using VLC player.

  Thank you

  Michael Rayman

  I finally found the answer to my problem:

  When they are disconnected from the internet, mysteriously, Windows Media Player 12 requires that you check a checkbox in tools > Options... > zone settings tab player called "Internet connection (ignore the other commands).  Once this box is checked and the settings saved on APPLY, then Windows Media Player 12 will play videos served by the local IIS server on the same machine, while disconnected from the Internet.

• ESXi host sees no data store after the reboot

  Hi all

  I'm new to the community and ESXi itself.  Everything has been working great until today when I rebooted my host.

  I installed it on a Dell T110 server, we had in the back for testing.  It has a 250 GB HARD drive installed in the case.  ESXi installed fine and I had 220 GB or more storage at my disposal.  Multiple VM installed, and once again, everything seems to work properly.

  Today, I wanted to activate usb passthrough for a Server 2008 VM I installed it, I went through the process and had to reboot the host at the end.

  After the restart, he seems to have forgotten the HARD disk that is installed and is no longer, I see my store data or virtual machine access I had running.

  There are a couple screenshots attachedthat screen what I see.

  Thanks for any help or advice!

  Is this the same controller that is attached to the 250 GB HARD drive? Passing the controller to the virtual computer may have unpresented it host, then you won't be able to access and to store configuration settings. Since this is a test system you can consider / try to run "Reset System Configuration" from the DCUI. If this does not work, you may need to reinstall ESXi of CD (the VMFS retaining of course data store).

• Wireless router is disconnected from the PC (s) during the use of Firefox 37.0.1

  This problem occurred for the last 2 weeks whenever I use Firefox on each of the 2 PC's I use it every day. The problem may occur a few minutes after the start of Firefox, or it may be hours of continuous use before the connection is lost. It's okay if I'm in Firefox by itself or have the background applications running, but without a doubt requires Firefox runs before I see a problem.

  Configuration: WIN 8.1 and VISTA 64. the two latest updates.
  LAN: cable modem and Belkin wireless router; together with the latest firmware.
  Firefox v37.0.1 without add-ins or modules. Start page is 'empty '.

  Symptoms:
  Status bar Windows shows that I'm disconnected from the router.
  Router and the modem status LED shows that I am connected to the internet. Same thing for the VICTORY of the network status app. It shows no connection to router.

  The problem can be temporarily fixed by power cycling the router. Or, in the meantime just a random delay the connection may (or may not) be restored on its own.

  I also use a standalone PC application that streams the text given in short bursts and runs all day (no video or music... just short lines of text) with no problems until I launch Firefox in the background. Then he can go a few hours before the connection to the router is lost. I also often watch videos on my Tablet without the router problems. While typing in this issue on a PC I was disconnected from my router. I'm hoping to get some suggestions as to what to inspect or modify. Thank you!

  Fred, I had to leave the House early this morning and had no time to dig a cable long enough to reach my modem to try your suggestion. But, what I did was half of your suggestion. I pushed the reset bit recessed on the modem and left the House around 08:30 with Firefox running on both computers. Seven hours later everything is normal. No router disconnects and I gave a very good workout system.

  I have also now initial notice that connects to the web sites are faster.

  It is obviously a logical explanation for what was going on, but to an outside observer (), I see absolutely no logical link to the 'solution' for the rest of the universe. I won't lose sleep on. And I'm going to ask you more specifically when the next puzzle problem occurs! Thank you, Fred!

• SOLUTION for your HP printer disconnect and/or constantly disconnecting from the network

  If you are having a problem printing, scanning or fax with any HP printer because of this be disconnected and constantly disconnecting from the network, here again is the fix!

  I thought that this all after several failed attempts with HP Support, my Internet access provider and various troubleshooting tasks including reinstall the HP software and more and more.  Well, through self teaching on internet and exhausting search for 6 months, I FINALLY thought to it.  OMG!  I'm a paramedic (not IT) and a little computer but far not an expert.  I have all of you here!  Nobody seems to have the answer, but I'm sure that I'm doing it to 97%.  Whatever it is, if it please answer and let me know that it worked for you!  :-)

  It doesn't matter if your printer is installed cable or wireless.  You don't reinstall your software, no recycling power of your printers or your router/Modem.  Your printer is unstable on the network and continues to log out or disconnect from the network it is NOT because the software is glitched, it isn't a firewall problem by saying, is not a router problem, is not a problem with your power cord, because most networks use a 'Beach' and IP addresses for security reasons This kind of "cycles" the IP addresses of the devices to reduce the risk of an attack.  A printer is not a threat, but the 'network' don't own human intelligence, so he does not know this.  Here are my step by step instructions on how to basically your printer address IP (static IP) instead of change back through a cycle so drop your printer on the network or disconnected.

  Funny, if you're someone who has had the elements in your print queue, they will not print, and you turn your printer off and on again and suddenly your print... well documents, join my club.  The reason it works is that when you turn on the printer, it starts with the same IP address before cycle.  If you are someone who is sitting there for a while and all of a sudden your printed documents without changing you something... it is because through the cycle of change of IP address, it hits your printers IP address and the network would allow him to print.  Not very funny, I know.  It took me forever to figure out why my printer would print sometimes, but not always.  Since I thought at this point, I can SCAN, PRINT, and use all the features of my HP software installed like HP, Photosmart Essentials Solution Center.

  On your printer, go to menu/Setup/network and press OK.  In the network menu, print a "network configuration page" so you can see the IP address and other settings of your printer.

  Now, back to the main menu on the screen of your printers.  Or you can go to your web browser and type the IP address using decimal numbers too and this will take you to the web page of your printers.  Choose: setup\network, then press OK.  Look for the IP settings and press OK. Choose "manual" instead of "automatic". Manually enter the IP address it as well as the default gateway that you can see the Network Setup page you printed earlier.  Note: If you manually set the IP Address of the printer, make sure that it is outside the range of your router's DHCP. Otherwise you might encounter a problem with IP addresses on your network duplicate. (If you don't know how to do this, write back and I'll explain).  Don't forget to click "save changes".  Now, restart your computer, and print just what you want.  :-)

  A trick I often use with DHCP network printers:
  In printers and faxes, right-click on the printer and select "Properties".  Click Add a new port.  Choose standard TCP/IP port configured for the host name of the printer. Read the host name of the network printer configuration sheet.
  
  Using my method means that you always connect to the printer even if its IP address changes (which can happen with the dynamic configuration). This does not jeopardize the security of your network.  It shows just your printer to stay put and stop traveling the highway of IP address.  :-)

  The DHCP range is the range of IP addresses that the router distributes automatically as devices to join the network.  The DHCP range is determined by the router and each brand has a range that is set at the factory (which can be changed by you).

  Default value for the DHCP of your D-link is 192.168.0.100 to 192.168.0.199.  Thus, outside the DHCP range est.2 a.99.200 a.254.

  Is a handy cheat sheet attached.

  You can change this interval by entering the router settings page - type the router's IP address in a browser, enter the login information and access the DHCP parameter area (varies depending on router, hunting around).

• Tecra A2 crashes when you are disconnected from the internet

  We have a customer with a Tecra A2 provided by ourselves that, after 5 months without a problem from time to time, hangs when it is disconnected from the internet.
  Reboot the laptop and the internet can be found sometimes up to 20 times and then it blocks again when we disconnect from the internet IE. A Ref post causing VOIP problems were found and the software disabled and disconnected hardware. No difference. Running XP SP2, IE6, Kaspersky Anti Virus, Tiscali ISP ADSL, modem ADSL Tiscal (a new requested just in case). A lot of work to do and lose valuable time with customer problem.
  Thank you

  Hello

  It seems that a 3rd party software causes this very strange problem.
  You suggested that VOIP is causing the problem. Well, the problem is that Toshiba doesn't support any 3rd party software and applications.
  What I can suggest is to check the Event Viewer logs. You will find all the errors that appear on the OS. Double-click the error and you should see the description of Microsoft.
  Maybe you will find a solution.

  Good luck

• Current file to use when it is disconnected from the network wireless/wired - shared network drive

  Hello

  We have a problem where we receive a "file in use" message when you are disconnected from the network. To reproduce the problem, what we do is:

  (1) connect to the wired network wireless disabled with

  (2) create a test document

  (3) to enter text and save on network share

  (4) remove the network cable

  (5) add additional text

  (6) reconnect the network cable

  (7) try to save the file to the network share

  At the beginning by clicking the X is the new message you want to save. Click Yes and the message arrives until the next time you hit the Hit of X no. and he loses the last change.

  From here we then go up to the network share, open the file and it comes up with "file in use. Open read-only. File is opened by us (Administrator account), and there is NO temporary file in the shared folder.

  Tried so far:

  -Run net config server/autodisconnect:-1 for trying to stop it disconnect the share

  -Checked pane, pane preview and off 'display the description of the pop-up window for folder and desktop items '.

  -Windows Update

  We try to reproduce on wired connection, because it is easier to reproduce that disconnects wireless. Seems to have an impact on several operating systems. Share folder is shared on a Windows 2008 R2 x 64 machine.

  Is this a known problem or is there something that we can configure to try to prevent the locking file after logging out? Ideally, we want the decline to go unnoticed and provide uninterrupted service to the user, unless they are trying to save during the fall.

  Thanks in advance for comments :)

• When you transfer files to the internet, the router disconnects from the internet, but the network remains in tact.

  I have a wireless router Belkin g with 1 Server 2003 cable and 2 xp machines and 1 machine vista wireless. My problem is when you transfer files to the internet, the router disconnects from the internet, but the network remains intact. I cannot remote in all computers, but not internet. Once I have restart the router, everything works fine. I was wondering if anyone else has had this problem and how to fix them.

  original title: problems with the router.

  I have no solution for you.  It seems more likely to me that it is a hardware problem - but if it was related to traffic, I would expect that the problem on the downloads more downloads.

  In addition to DSL reports, you could try to ask some of the forums that specialize in the updated firmware for wireless routers.  This is not to say that you need to install the modified firmware (although there may be good reasons to do so), but people who do usually firmware mods are much how the equipment works and what might be its potential failure modes.

  Is one of the best-known sites DD-WRT.com, but there is one list of other here: http://en.wikipedia.org/wiki/List_of_wireless_router_firmware_projects the firmware on these sites was originally designed to run on Modem Linksys WRT54G, but applies generally to Linux with chips Broadcom - based wireless routers and DD - WRT claims that its firmware takes care of some Belkin routers.  If your router is one of those on what DD - WRT will work, there will probably be someone in the forum there will have something for you.  See the list here: http://www.dd-wrt.com/site/support/router-database

• This family member is able to make me become disconnected from the internet.

  Windows IP configuration
  Windows XP / Home Edition / 2002 Version / Service Pack 3

  A member of the family interferes with my computer and worse me. It's work! This family member is able to make me become disconnected from the internet.  I'm not sure how he does it, but I have a feeling that he is able to see my IP address and it blocks my IP address of the router. I'm not familiar with TCP/IP or DNS settings. Here are some of my settings, perhaps you can direct me in how to change a parameter, so it can stop.

  Windows IP configuration
  Host name...............................................
  Primary Dns suffix...
  Node Type................................................ Unknown
  The active IP routing... NO.
  Active proxy WINS... NO.
  DNS suffix search list...

  Whether by TCP/IP or DNS, I believe that the family member is accessing my computer. Is it possible to change these settings where the family member is not able to see my local IP address? I need to change the DNS server settings and change TCP/IP settings. Maybe I'm wrong and you can tell me what I should do to fix this problem. Thanks in advance for your answer.

  As already mentioned LEM that the rule on the router has an absolute rule that can and cannot access the internet or other network resources.  I suggest you lock your computer, turn off the server, Remote Service registry service and Remote Desktop and change the password on all administrator accounts.  Make sure that your firewall is enabled and have it block all inbound traffic local.  Then talk to the guy that controls the router and ask him to lock the router with a password, the only way to bypass the router, then will be by resetting it and the router administrator will know if everything else does.

  Having said that your problems are probably not caused by another Member of the family, it could be caused by flaky or failing hardware, bad cable, bad router, network card bad, if you really think that your problem is caused by a member of the family of your computer, then your question must be addressed and brought to a head in a "family meeting" rather than in a public forum on the internet.  There is not a lot of people read here can do to change the behavior of the members of your family.

• My computer is constantly disconnected from the internet and to reconnect I just unplug the cable for less than a second and it starts to work instantly.

  My computer is constantly disconnected from the internet and to reconnect I just unplug the cable for less than a second and it starts to work instantly. Does every 5 to 10 minutes and it gets frustrating. It is not the cable modem because it is constantly connected, and I repeatedly checked.

  Hello

  Your router could be suspicious here, you have successfully updated its firmware as a possible solution? And I would like to
  Update your WiFi drivers on computers. How you are positioned in the router? Are there
  obstacles in the path?

  Actually try updating your driver and disabling the network logon.

  Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
  version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
  Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  You can download several at once however restart after the installation of each of them.

  After watching the system manufacturer, you can check the manufacturer of the device an even newer version. (The
  manufacturer of system become your backup policies).

  Repeat for network (NIC) card and is a good time to get the other updated drivers as Vista like
  updated drivers.

  I would also turn off auto update for the drivers. If the updates Windows suggests a just HIDE as they
  are almost always old, and you can search drivers manually as needed.
