I have an xp sp2 laptop user using cifs and recently it just stopped working
for that user. I have reset their simple password and nothing I do seems to
help. other users in the same context can login perfectly fine even from
that laptop so its not a laptop issue or a context issue. I create new test
users in that context and they work as well. Nothing special about the
setup. it just refuses the passwords as if we are typing the password wrong
and eventually nams complains of intruder detection.

any ideas?
