Can’t access server by UNC

I am unable to access a server by unc path from my admin workstation, but I can access by unc if I use IP. Funny thing is I can access the server by unc anywhere else. I can ping the server by name, and Netbios is enabled. I did have folder redirection setup, but removed it. I still get a message that I am no longer connected to the server and that I need to synchronize, but each time I try to, it fails. Any suggestions out there?
