Client Machine cannot see Active Directory

I have one client that is unable to see Active Directory or access shares via
\\servername for our new NAS

but mapped drives work ok and authentication is ok.

I can see the client using both the FQDN and the Netbios name using NSLookup
from any PC on the network, but from that PC I get an error that the domain
doesnt exist.

I have removed the PC from the domain, cleared the DNS cache with
ipconfig/flushdns, deleted the computer record in AD users and computers, and
readded it and got the same result. I am not sure what I should try next.

I have not seen this issue with any other clients.

Any assistance would be greatly appreciated

thanks

Derek
