• ESXi host running 6 VCSA disconnected from the vCenter

  Hi guys,.

  I have a weird problem with my vCenter build 6. Single cluster of ESXi hosts. Running VCSA 6.0 and 6.0 ESXI. Making a storage of the vCenter vMotion initially got stuck at 77% and the ESXi host running the disconnected from vCenter vCenter. But I can connect directly to the ESXi host with vsphere client and see the vCenter VM works perfectly well. If I try to manually connect host ESXi and vCenter, I get the error "Failed to contact the host specified") both are in the same subnet and VLAN. I can migrate to other virtual machines without problem. I even restarted the host and yet I am not able to connect to vCenter. The host connects to vCenter if I reboot vCenter, but after a few minutes, disconnects again (even if no task does run on this topic.) I have no HA or DRS enabled at this point that I build this new environment and only presented a single LUN as a store of test data to the cluster.

  Any ideas?

  OK, I think I fixed that or have at least a work around. So the underlying question was hiding ID mode/CPU EVC. I'm under the cluster to a level of EVC to reduce until I have migrate workloads from old environment and I think that this created a problem for the unit vCenter. To resolve this problem, I turned off the unit, directly connected to the ESXi host that had the camera running, edited the virtual machine and reset the masking of CPUID. Also, I've hidden the flag NX/XD of the guest. It's temporary (I hope) as once I increase the EVC to the Haswell, I will expose the NX/XD comments and test. For the moment, it is of the workaround I did. It may be of some use to someone.

• 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.

• 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,.

  Johannes

  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

• Disconnect from the storage data store

  We have two datacenters (Server Vcenter linked mode) - A & B

  Site servers A and B are replicated via san (at the end of storage no SRM)

  Note - what is the known issue in environmental - issues of SAN - every day there are stores in the event of disconnection from the storage data. (Question is 4 months old now). in the Windows Server performance issues.

  For the recommended HP fix update the firmwares of controller on both sites (3 HP EVA controllers) which has been successfully complete however problem has not been resolved.

  There are a lot of outages caused by the problem of storage in the environment. As an example under Server is unresponsive due to the store being disconnected from data storage.

  

  Vmkernal newspapers indicates that it will fail on the physical path

  

  Note storage array - is active active and political path for host ESX is alternating

  What measures can be taken to correct the problem?

  Thank you

  What about port enc on connected to EVA in SAN switches? You have CRC errors and if so, whether the counter has increased? Reset the counter if necessary so that you can monitor it.

  What, EVA connect? Any excessive number of links and housing check the errors of State?

• How to disconnect from the Mail application built into Windows 8 Pro

  I think that this old question / thread has been neglected (closed) and went without a good answer.

  Citing the answer of the moderator of this thread.
  "

  Hey jayRads,

  There is no concept sign in email and applications on the Preview version of consumer Messaging. If applications use the credentials you entered in your Windows profile, you will need to disconnect your account under settings of the PC users.

  -Isabelle '.
  and we know that this is not a real answer to the question.

  Since I only have a Local account signed in Windows 8... and when I click on the mail and forced me to Sign In (add account MS)... There should be a disconnect somewhere after I entered my hotmail account. Logically faulty if there is really nowhere to disconnect my hotmail. Even used Credential Manager/ne shows not my signed in accounts.

  NOTE: All I can do is to remove all accounts from the e-mail settings, but it affects all applications (Messaging, people, etc.) which usually isn't my idea of disconnection from Mail only. :(

  I want to just sign out since the Mail application (will also apply to applications that require a signature in) is possible.

  Please enlighten me in this situation.

  Thank you
  Ferdie

  Hi Ferdie Miranda,

  Thank you for choosing windows 8 and we join on our community.

  I understand from the description of the problems, you want to know the way to disconnect from the Mail application in Windows 8.

  Windows 8 Mail app has been designed so that it will keep you in connected mode all the time so that you will be able to check your e-mail without connecting to the Web-based e-mail.

  The steps in the thread you mentioned are quite correct.

  If you want to disconnect, please delete your account.

• 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!

• Why is that every time I open an application that my phone disconnects from the wifi

  Everytime I open an application that my phone disconnects from the wifi.

  Here's a tip for the user on the problems of Wi - Fi. Suggest from the top and bottom. Maybe one of them will help you.

  (1) perform a forced reboot: hold the Home and Sleep/Wake buttons simultaneously for about 15-20 seconds, until the Apple logo appears. Leave the device to reboot.

  (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

  (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth).

  (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

  (5) disable the prioritization of device on the router if this feature is available. Also turn off all apps to VPN and retest the Wi - Fi.

  (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

  (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

  (8) backup and restore the device using iTunes (ask for more details if you wish).

  (9) go to the Apple Store for the evaluation of the material.

• 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

• Try to disconnect from the iCloud on my Macbook Air (El Capitan 10.11.2) but in system preferences, it says I have to create a new password for my Admin account - and then the new password I get says "password does not match"?

  I am trying to add my outlook email account to the Mail app, but because it's the same email for my iCloud, for some reason, they are linked, and I discovered that I need to disconnect from iCloud, and then add the outlook account.

  But when I try to disconnect from the iCloud in system preferences > accounts on the internet, it says I have to create a separate password - but when I get one it says "passwords do not match"? I tried to do different and same, nothings working: S

  The dialog box is like this:

  [Stop using iCloud?]

  Create separate password for (name of the admin account)

  -You will no longer be able to log in or unlock your screen with your icloud password, and you will need to remember two passwords separately.

  iCloud password: __________

  New password: __________

  Check: _

  Index of password: __________

  [Use the separate password?]

  Not sure why that is, that the password does not when it's supposed to be the new s password?

  Also, I would like to know what to put in the box check?

  Help much appreciated!

  Thank you

  Oh wow. I just realized I was leaving the case confirm the void and the message "password does not match" mentioned. I just need to retype my password. Hilarious that I have not worked this one earlier.

• Satellite A200 Win8 64bits - Atheros AR5006EX disconnects from the network at random

  First of all, sorry for my bad English.

  Hi, I installed W8 a few weeks ago and I have a problem with the WiFi. The adapter disconnects from the network at random. Not a protocol TCP/IP fail because I don't lose the connection to the internet, I lose the connection to the network for everyone.
  Simply disconnected from any wifi network.

  I have read that wifi chips Qualcomm have problems with drivers in W8. I tested many pilots and all do not work properly.

  Any help?

  The wifi card is: Qualcomm atheros AR5006EX and the laptop is: Toshiba satellite A200-1TP.

  Drivers I tested (and didn't work):

  http://drivers.Softpedia.com/get/network-card/Atheros/Atheros-AR5006EX-WLAN-driver-300119-for-Windows-8-x64.shtml

  Thank you!

  Do you have these problems with the operating system supported?
  I mean A200 is pretty old machine and certainly not supported for Win8, so it can be a problem with all of this, especially with the drivers.

  Let's see if someone else has the same machine and have the solution to this.
