Power PC 7100/66 to Windows Server 2003 R2 SP2 not connecting.

PowerPC 7100/66

Mac OS 9.1

Connected to a 10/100 Windows ethernet network via a MacSense Nubus RJ45 ethernet card.

Connected via 3Com 10/100 hub.

AppleTalk and TCPIP point to the ethernet card.

I can't connect to the Windows 2003 R2 SP2 Server.

Server is running File and Print Sharing for Macintosh services.

There is a MS UAM Volume.

What am I missing??

Thanks,

Joe
