dot1x port authentication

[9s.pappas]

I have dot1x port authentication enabled on a 3550 and it works, sort of. My XP workstation can access the network (I can browse, ping, telnet) but the domain login script does not run or has timed out and I lose my drive mappings. Any suggestions?

I need to clarify one thing. This works when I assign the VLAN to the interface. It breaks when I assign the VLAN via ACS.

Are you using machine-auth and do you have KB826942 loaded?

Yes on both.
