Mounting an NFS share under Windows Server 2008 or 2008 R2 fails, mounting under Windows 7 works fine

I am working with a mixed network of Windows and Unix/Linux machines. After making sure File Services for NFS is installed and running, I can mount an NFS share on any Windows 7 machine. When I try to mount an NFS share on any of my Windows Server 2008 or 2008 R2 machines, it fails with the uninformative:

Network Error - 53

which translates to 'The network path was not found'

I can ping the NFS servers without a problem, and I can get the list of exported shares with the 'showmount' command, so I don't know that the error message is telling me anything useful.

I have matched up settings between one of my working Windows 7 boxes and the servers:

They are all using TCP only (no UDP)
They all have the provider order set with NFS at the top of the list
None of them are using AD or Name Mapping settings - I am passing through the Unix UID and password with the -u: and -p: switches on the 'mount' command.

I have looked over a previous question here, which the author answered himself: http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Q_27153957.html 
His solution/answer of changing the timeout to 30 and the retries to 5 has made no difference.

Any thoughts are welcome, and thanks in advance!

Make sure that the NFS share is exported to the IPs/systems that windows server can access.

Use tcpdump on the NFS share server and see whether it sees the network connection requests.

We figured it out: The servers were not in the NFS Export group but the Windows 7 machines were. Adding the servers solves the problem.
