Security: Windows 2000 PDC can't access XP Workstation

[Guest]

Hello...

I'm having a heck of a time trying to figure out why my domain controllers
can't access shares (c$), registry, or manage my Windows XP workstations. I
can however access a Windows 2000 Professional client. All workstations are
in the same OU, so they're getting the same security templates applied to
them.

I'm sure this is just a group policy/security setting I'm missing, but I for
the life of me cannot figure it out.

Just yesterday I switched Lan Manager to use only NTLMv2 and reject LM/NTLM.
Users can log into the domain just fine. It's only when I try to access
workstations remotely from any domain controller.

By the way...when I say "can't access", what happens is I get prompted for a
username and password when I try for instance, opening my computer and typing
in \\bcmci111\c$. I'm using valid usernames and passwords for the local
computer as well as domain, and none of them work.

Hrmmm....no one has any idea? I'm still at a loss on this one.

Someone get Uncle Bill on the phone!
