I have a small network with 4 pcs. 1 is Vista 64, two XP Pro and 1 W2K. Peer
to Peer. All machines could see the other machines shares without problem.
The net browser is the W2K machine.

I had to change the chassis of 1 XP Pro box because of heating. everything
was phisically moved to another chassis, no OS change watsoever, nor
component changes. Now, both XPs and the W2K can see shares in each other
normally, as before, and they even can see shares on the Vista box.

But the Vista started behaving in a wierd manner:

Vista to W2K: sees shares normally
Vista to WXP Pro not modified Sees shares normally
Vista to WXP Pro with new chassis: The XP does not recognize the vista User
and Password. I tried as Administrator, as user, changed passwords in both
XP and Vista, created a New user in both machines with and without password,
and still the XP refuses to recognize the Vista credentials.

Any clue will be welcome. I don't know how to trace and record what is
happening, so as to analyze it with more detail.

Thank You
