When I attempt to access my PDC from the network using a UNC path (\\pdc\share) I get the error "\\pdc is not accessible. You might not have permission to access this network resource. Contact the administrator of this server to find out if you have access permissions. Logon failure: the target account name is incorrect." However, if I browse by IP address, I have no problems (i.e.: \\192.168.1.1\share). What could cause this, and how do I fix it?
