[Samba] Some users cannot login on some clients

A simple setup: Samba 3.2.5 (Debian/Squeeze) set up as a PDC with a
couple of Windows XP (SP3) clients and roaming profiles. This has been
running for several years without trouble (thogh people did not really
roam but rather sticked to a single machine).

Now someone tried to log in on another PC and failed ("wrong login or
password"). Investigating this it turned out that NOBODY can
authenticate anywhere, EXCEPT those machines (in most cases just a
single one) where he did so in he past. BUT the samba server tells
"authentication succeeded" in its log files nevertheless.

So the situation is: everyone can work on at least one PC, on every PC
at least one login is possible (which suggests to me that the samba
setup is correct).

I have absolutely no clue what could cause this behaviour. Are there any
patches to Win-XP which prohibit logging in with a PC when there is not
yet a local copy of the user profile? Or anything else?

Where should I even start looking? Neither samba nor Windows XP is
providing me with any useful debug output.
