logon problems

This is really annoying. One of our customers has a 2003 server and about 35
users running a mix of xp and 2000 clients. Two of them repeatedly are unable
to log on with the classic ‘domain server not found or wrong username or
password’ message whoever they try and log on as (and the client dns settings
are pointing to the server and they exist in the forward lookup zone) the
only way to log these clients on is to boot them out of the domain into a
workgroup and back into the domain and then they can log on, until the next
day or the day after when exactly the same thing happens. Both the iffy
clients are running xp pro sp2.
I do not know what computer account information is held on a client pc and I
suspect that if I did then then I would be a good deal nearer fixing this
than I currently am. If it were one pc then I might just rebuild it but two?
Any ideas?

Can we see an ipconfig /all from this client and from your DC please? Can
you also provide any Event log errors and anything you may have running on
the DC or the client (anything at all, such as the XP firewall, a 3rd party
firewall, 3rd party utilities, antivirus, anything).

Thanks.
