We got issue that user could not access their shares in Domain controller.

When we check we found that all services are running (domain service, server,dfs)

 Tried to ping the server ip for the server itself , got the below error

c:\>ping xx.xx.xx.xx

Unable to contact IP driver. General failure.

 Tried to ping the loop back ip

c:\>ping 127.0.0.1

Unable to contact IP driver. General failure.

 To solve the about issue we had done the below.

As we can’t even ping the loopback address, it seems that the TCP/IP stack may be corrupted.

Logged into the server via admin account , turned off the UAC then taking the following steps to reinstall and reset TCP/IP heap to its original state:

 1)Run the cmd as administrator (operation requires elevation (Run as administrator).

2)Type  netsh int ip reset in the Command Prompt shell, and then press the Enter key.

3)Restart your computer.

 Eventually pleasedownload and update the network driver to the latest version. If you server is VM, then goahead and update you VM tools.

 Hope this might help!!!
