• Vista Home premium - cannot remove a network connection.

  I have administrator rights and remove button in "manage network connections", I get a pop up - but the connection that it does not remove.  Several reboots.
  Pls advise.  Thank you

  Hello

  Follow the steps below to remove the old network connections on a Windows vista computer.

  (1) use your mouse to click on the start menu, and then select Control Panel.

  2) click the button on "Network and Internet" Control Panel and select network and sharing Center.

  3) click on the tab "manage network connections".

  (4) find the old network connections you want to remove in the scroll bar. According to the number of connections you currently have in Windows Vista, it is possible that you need to scroll a bit to find the one you want to delete.

  5) click on the old connection you want to remove.

  6) click on the button 'delete '.

  (7) to confirm your selection by pressing 'Yes' when asked if you are sure you want to remove the connection. You can also choose to press 'Cancel' or 'No' to return to the previous screen and prohibit the removal of the connection.

  (8) notes that you can also change the network through the Network Wizard. Simply click on start, then "Connect To" and "show all connections".

  (9) select the network connection you want to change by clicking right on it and selecting the option you want. You can choose 'Disable' the connection, which would roughly have the same effect that completely removing, making it inactive.

  (10) press the button 'Delete' after clicking on a network connection in the network connection window. This will completely remove the connection in the same way that detached from the control panel.

• Questions of ESXi 5.1 ISCSI--> cannot establish a network connection (continued)

  Hello world

  I had a problem there not too long ago (thread link below) where my ESXi hosts could not establish a connection with an IBM DS3500 on start up and "rescan", however their connectivity worked correctly without any problem after commissioning and when a "rescan" finished. We determined that the most likely cause was the unit IBM itself. However, I wasn't completely satisfied.

  In order to deepen the question and dismiss my guests being the problem, I created a unit ISCSI myself with two new hosts of ESXi 5.1 (version 1157734).

  ESXi signals that it cannot connect to the initiator ISCSI (network error) - but it can run virtual machines and browse data stores?

  The configuration is the following:

  Test environment:

  2 x ESXi 1157734 hosts

  1 x server Freenas ISCSI (ZFS R10)

  At the start of my ESXi hosts in the test environment, download the same error as our production environment. They also put on the same error message (in the event log) when I "rescan" map of the ISCSI software. However, once the scan is finished, I can't see any error message and everything continues as it should (Round robin, active active). I can get a brilliant flow also. It's as if the errors are almost... false positives?

  Example of the error message (test environment):

  Connection to the iSCSI target

  IQN.2011 - 03.org.example.istgt:iscsi on vmhba35

  @ vmk2 has failed. The iSCSI initiator couldn't

  establish a network connection to the target.

  error

  17/10/2013-08:33:35

  ESXi hosts are configured as follows:

  Test environment:

  • (ESXi hosts) Two network cards for ISCSI, one for VM traffic
    • NIC1: 10.20.20.2/24, NIC2: 10.30.30.2/24
  • (Freenas) Two network cards installed on the ISCSI device (dedicated to ISCSI traffic)
    • NIC1: 10.20.20.1/24, NIC2: 10.30.30.1/24
  • ESXi is set to round robin, which works properly (I can max on both ports at the same time)
  • Two VMKs are related to the ISCSI Software initiator and defined to dynamically discover the two ISCSI addresses
  • Unity of ISCSI and the hosts are not on the VLAN, the switch is dedicated to ISCSI traffic (However in the production, the two networks are separated by VLAN.) I removed the in the test environment to simplify everything)
  • The vSwitches (who hold a single VMK for ISCSI) are fixed:
    • "Promiscuous" mode: reject
    • Change of MAC address: accept
    • Forged passes: accept
    • The traffic shaping: disabled
    • No NIC teaming (obviously)
    • Each VMK inherits the settings of these

  Quick points:

  • My hosts use VMware approved NIC in my test environment. My production environment runs on full VMware hardware approved
  • Can I use ping of vmk join each each VMK ISCSI initiator
  • I can use the nc-z target_ip 3260 command to check connectivity to the port
  • The ISCSI test has two network adapters, each on 1 Gbps ports
    • I can get around 800mbps per port when copying lots of files (both ports are active)
    • I see no error in copying a large number of virtual machines around, or backup files
  • I only see errors on start up and "rescan".
  • I have two network adapters on each host ESXi dedicated for ISCSI. Each NETWORK card has a single VMK. A single mapped port on ISCSI, the other is mapped to port B (I used to have two VMKs by nic, but I removed that in order to simplify everything)
  • I have updated the firmware on our switch of production. No results
  • I've used 4 different switches in order to avoid a network problem. No results
  • I tested ESXi versions 5.0, 5.1 (799733 & 1157734), all have the same mistakes
  • The ISCSI ports are on different networks according to the VMware (I was told not to put on the same network VMKs)

  Any ideas? It's starting to drive me up the wall. Any help would be greatly appreciated

  I've seen several times in recent months and was beginning to think it is specific to the HP P2000 units because it's the only time wherever I saw him! I now believe that ESX/iSCSI rather than issues of driver or table.

  On my last install, I found that errors occur as soon as the table is connected, i.e. before any storage is displayed.

  Single host ESX, no guests. 2 Intel adapters to 2 HP past by dedicated HP P2000 1 GB table with all 8 wired ports.

  All roads are good, all lights are in the State expected.

  It did not affect the use of the storage in question to any site, so there has been no need / a momentum of any further investigation.

  B! 886y annoying however!

  I found the problem (s), even if I am always left with a few questions.

  During this process, I have disabled the firewall, but that did not help. However, I noticed 'tweaks' accessed via the tab 'Advanced' in 'Microsoft Firewall' which looked like, they must be checked in order to access the internet. I checked these and reintroduced the firewall. After I got things working, I unchecked them and things still worked so I obviously don't understand what these parameters.

  The solution:

  (1) I have to go straight from the modem cable to the computer. I can't have a cable modem, router wireless, computer, even if using hard wire, and even if this same configuration works with another computer. Also, I can't use a cable length to go from modem to the computer. So, it seems to have had a problem of cable length. Power problem? Only connected to this computer devices are the mouse, the keyboard and the Ethernet. Would not this be fixed with an upgrade of the power supply? Or is it due to the quality of the Ethernet hardware on the motherboard? It's a Dell Vostro 200.

  (2) in back and forth between configurations while following the problem, you must think to unplug the modem to reset between each configuration. You may have stumbled upon the solution, otherwise he's not shot. Also, I unplugged the cable from the modem when you reset data cable - do not know if it was necessary. I wanted to limit the degrees of freedom that I had a lot, as it was.

• Computer laptop Windows 7 can not find wireless network connections

  My Samsung RV510's laptop had windows 7 on front and without wire worked but recently my hard drive for this laptop broke and I had to get a new HARD drive. Now I have a new one that I installed windows 7 on it and now it cannot find wireless network connections even if there is a broadband router in the same room as the laptop. When I try to connect to a wireless network, the computer does not find.

  You have turned on WiFi?  Have you checked Device Manager to see if your wireless network card has a driver?  The different procedure for Urning edited that WiFi on East and model, so you for each brand will have to read your user guide - I promise he won't give you the leprosy!  :-)  To check the driver, click Start and right click on computer, then click Properties.  Click on Device Manager and look for the entry that says that the network cards.  Click the arrow to the left and look to see if

  There is a! or? next to him.  If so, you must download the driver appropriate from your manufacturer.

• I can't connect you on some client computers on a domain environment unless I have remove the network cable.

  I have almost five machines on my LAN that cannot log on to the domain, unless I have remove the network cable and then it connects.
  Please advise?

  On the domain controller or problems by communicating with the domain controller, when you remove the network cable, you connect with that caching of credentials.  Also look at the DNS settings on the RODC, the RODC DNS should point to itself, make sure that the machines are all on the same subnet.

  Hello

  Maybe this can help.

  These steps and tell us where is the breaking point.

  Check the Device Manager for the wireless card valid entry.

  http://www.ezlan.NET/Win7/net_dm.jpg

  If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

  Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

  http://www.ezlan.NET/Win7/net_connection_tcp.jpg

  ------------------

  The wireless card drivers much also install utility wireless of the seller.

  Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

  ----------------

  Make sure you firewall No. preventing / blocks wireless components to join the network.

  Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

  If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

  party like Hello and NetMagic 3rd network managers can block local traffic too.

  ---------------------------

  Stack TCP/IP work should look like.

  Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

  http://www.ezlan.NET/Win7/status-NIC.jpg

  Description is the data of the card making.

  The physical address is MAC of the card number.

  The xx must be a number between 0 and 255 (all xx even number).

  YY should be between 0 and 255

  ZZ should be between 0 and 255 (zz all the same number.)

  The date of the lease must be valid at the present time.

  * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

  * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

  ---------------------------------------------------

  A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

  Above everything is OK, you must be able to connect to the router.

  Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

  If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

  Enable security wireless after you eat to make a functional connection.

  Hello

  Can you explain what connection to a network means in your case?

  What exactly you want to connect?

  If you have a valid broadband (Internet connection), you are already connected to a network.

  If you want to check your wireless system follows this process.

  If as a result of this process, you find something wrong, tell us what it is.

  Most laptops have a physical switch for the wireless card. Read the manual of the computer and make sure that the wireless adapter is on.

  Check the Device Manager for the wireless card valid entry.

  Make sure you firewall No. preventing / blocks wireless components to join the network.

  Above everything is OK and it connects to the wireless router. Log in from any computer which is, or can be connected to the router with a wire wireless, disable wireless security, make sure that the wireless streaming is enabled and try to connect with no. wireless security.

• Firefox cannot connect to a local server subdomain if no available network connection.

  Hello

  I have a laptop that is configured as a local server using Apache. On this, I use "localhost" as the domain and have several subdomains.
  Now, if I have no network connection (to any other device) available on this laptop, and then with Firefox I am only able to access the domain 'localhost', but none of the subdomains and get a "Server not found" error on these. If I have a network connection, I can access the domain and subdomains with no problems.

  What it could be and what can I do to make it work without a network connection?
  I also tried with Opera and Chrome, and they can access subdomains anyway.
  Unfortunately however I prefer Firefox, then Yes... I am here.
