I'm using a Windows 7 x64 computer to map a network drive so it can access files hosted on a Tiger (10.4) Mac OS server that our artists place their artwork on. When I try to map the network drive or try to access the location through a Run command on the Windows 7 machine it'll prompt for credentials. Nothing works except for the local admin account that we use for the Mac Server.
The Mac Server is on the network and uses Active Directory. I have an "art group" that has access to the file share on the Mac Server. I'm also able to connect to the Mac Share just fine on a Windows XP machine which leads me to believe that it's something on the WIndows 7 computer.
