XP Slow in Wireless Login

Seems my XP machines in a building connected to us by wireless (2MBps) experience EXTREMELY slow logins. Our clients authenticate via Novell server/client for Windows first, then are connected to the appropriate Windows AD in our “home” building second. When I remove them from any Windows domains, they do perform better, though not as well as they should. Win2K pro mahcines seem to have no such problems.

I’m thinking the local policies from the AD are the issue here, but am not sure.

Anyone else run into this?
