Connecting Windows XP to W2K Server Active Directory

[Javier Colmenares]

Hi, After I successfully add a computer to a W2K Active
Directory domain and i restart the computer, when I try to
browse the network I get the following error:

Y: Drive is not accessible: The system detected a possible
attempt to compromise security.
Please ensure that you can contact the server that
authenticated you.

I appreciate any help on this matter. Again, I'm
connecting a Windows XP Professional PC to a Windows 2000
Server with Active Directory.

Thanks,

Javier
