2003 Server issue

S

Steve B.

Hi All:
If this isn't the appropriate forum for this question I would
appreciate the name of the appropriate forum. I am a NT4 guy just
coming into the 2003 world and have an issue with one of my customers.

Customer is complaining that everyday between 5:00 and 6:00 all the
computers loose their network connection. Server is a 2003 server
with a "default" load. Login takes a very log time to authenticate
(between 3 and 5 minutes)

Here are the problems I see:
The worstations are coming up with an error in the event log for
W32time saying that none of the sources are currently available.

The workstations are coming up with an error in the event log for
netlogon 5719 that there are currently no logon servers to service the
logon request and a host of other errors all pointing to a domain
controller that is unavailable.

These computers can see the domain controller though. They can get to
their files on the domain controller and a change to user rights on
the domain controller effects their local terminal as expected.

The server looks to be fat dumb and happy according to its event log.
I am just coming in to this situation but the customer tells me this
problem has existed since the server was installed. It seems to me
that they arent able to authenticate or get a time sync to the server
so after a number of hours it just drops them. Is this plausible?

Any clues what could be happening with my server? btw.. this is a
small network with one server and about 20 XP desktops.

DNS/AD config probs, IMHO. NetBIOS is working to find the machine and the
shares. DNS/AD is not (for logon authentication)
