Windows XP machines falling off corporate domain

Windows XP machines falling off corporate domain


Alright So here is our issue. In the past we have had a random computer or
two fall off of our domain and sure, we are able to go remove it, then readd
it and all is good. However here lately we've had 4 - 6 a day, all
appearing random, some happening more than once, others coming off that
never have. It appears they started happening after the following two
things happened one night:

- Applied Latest Windows Server updates (two weeks ago?)
- And due to the updates a reboot was required of AD / DNS / etc

We saw nothing about the updates that would have done this. Also,
everything appears random, and the "majority" of our machines are NOT
falling off... Nothing is corrupt on our AD servers ... GPO we have
disables windows firewall just thinking that maybe that GPO wasnt applying
and by some way it was stopping the computer to renew its account with AD.
We are chasing our tails here as we can not find anything to caus the up in
computers off the domain...while we know it has to be something.

Any idea's?

In the problem computer, if logon locally, can you ping the DC by name?

Starting with the basics, and assuming the Domain Controller is hosting the
Active Directory domain zone, are all clients using only the DC's IP address
for DNS?

We seem to be having the same problem. Do you look at the event viewer on the
local machines and see what system error it is giving you? We have done this
and it seems to be a kerberos issue saying there are identical named machines
on the domain. But there are no same named machines. Let me know if you
happen to find out what is causing this, I have been trying to figure this
out for awhile. Thanks.

Yea, on the local machine it'll sometimes show that there was another
computer on the domain by that same name..but have a $ or some sign in front
or behind it. I took a screenshot of my error...will post it when i get to
work.
