Hello,

- OS: Windows Server 2008 R2
- Environment: ESXi 5.5

We have 3 VMs, and ONLY the Server 2008 R2 is having a network issue as follow:

Suddenly, our application server has lost its network connection. I still can see the network adaptor on the device manager and network connections of the control panel, but when I type 'IPconfig' from cmd, it gives me an empty result.


1. I also run the 'windows network Diagnostics' and it says 'Windows couldn't automatically bind the IP protocol stack to the network adapter.'

2. Also, I tried 'netsh int ip reset c:\resetlog.txt' and 'netsh winsock reset', but it doesn't make any difference..

3. disable and re-enable the NIC did not make any difference.

4. Uninstall and re-install the NIC did not make any difference.

Please advise me to resolve this issue. Thank you!

Also

Run below command in elevated command prompt and analyse CBS log file.

sfc /scannow


If issue persists, I would recommend you to perform Inplace upgrade or Repair the OS.
