Unable to access NFS shares from Windows 2008 NFS client

We recently got a case where customer was trying to access NFS share hosted on Unix machine from Windows 2008. Issue was isolated to this windows 2008 client only.

We tried accessing the share from Windows client with the following options:

· Mount command returns Network error ‘5’

· ‘net use’ command prompted for a user name and password...

After entering the password it gave an error message

"Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again."

· Map network drive did not work

· Even UNC path gave error message "No permission on the network"

We collected network trace while trying to access the share using the mount command. But the network trace did not have any RPC/NFS packet. It indicated that no NFS connection was going out from the client.

We then check the properties for the Client for NFS service. On the “log on” tab we found that the “log on as” was selected a Local System Account in place of Network service.

We changed the log on as to network service and then restarted client for NFS service. Issue resolved and we were able to access the UNIX shares.
