Referenced account locked out

Hello,

Hoping someone can help me out on this one. I have a
Windows 2003 Server and a Windows XP machine. Peer-peer
using TCP/IP.

I am getting error "the referenced account is currently
locked out and may not be logged onto" when trying to
browse my Windows2000 Server machine from the XP machine.
I found article 816118 in the MS Knowledgebase. I remember
messing with routing and remote access. So I go into the
registry and make sure that the lockout is disabled. It
is. Then I go and stop/remove the entry out of routing and
remote access.

Any other thoughts as to what may be giving me this error
message? All user accounts are enabled. None are locked
out. I got this feeling that "user" accounts has nothing
to do with this anyways.

Thanks for any help.
Greg
