Thank you. Do you know if the legacy client would have the same issue?

I don’t think the kernel is use issue here as it’s able to communicate with your FOG Server and get to the point to try to mount your NFS Share, which comes off the server.

ON your server, can you let us know what OS you’re using? It’ll help us with command troubleshooting.

FOR UBUNTU TRY:
[CODE]sudo service portmap restart
sudo service nfs-kernel-server restart[/code]

FOR CENTOS/REDHAT/FEDORA TRY:
[code]service rpcbind restart
service nfs restart[/code]

There is no means of doing that that I’m aware of. Active Directory doesn’t have the capabilities to just rename a system.
