Win 2000 Server Closes MAC Network Connection each day at same tim

We have a cross platform network running several PCs and MACs. Each day at
the same time, we get an error message on the all macs and PCs that are
connected to the data on this server saying that "the connection with the
server has unexpectedly closed." Lately, it has closed at exactly 1:16pm but
a few weeks ago it was 11:59am each day. When this happens, we still have
internet access but no longer have access to our data server on which we
primarily work. Yet, as soon as it disconnects, we can connect again and it
is ok. On the macs, we just have to go to the chooser and reconnect with our
password but it runs fine after that. What could cause such a problem? Some
event codes from the server are "12061" , "1002", "8033" and "8021" ....
Not sure if these have anything to do with this problem or not but thought
I'd give them to you in just in case. Thanks for any help you may offer!

Sounds like you have an automated restart or reset of some network
service occurring or possibly an automated process such as a backup
creating a sudden heavy load on your network.

Verify that your server's event logs don't say anything about File
Services for Macintosh stopping/starting. If they don't then check each
switch and router between your server and the Macs.

The 12061 is a typically "Mac has been disconnected message" but that's
more informational about something happening rather than what caused
that something to happen.

8021 and 8033 indicate an insufficient rights problem in Active
Directory. Possibly, you have multiple domain controllers but they're
unable to synchronize their databases. Not sure if it's related to your
Mac problem, but this is a scheduled process. You can read more about it
here on Microsoft's site
http://support.microsoft.com/default.aspx?scid=kb;en-us;257250.

1002 also seems to relate to an authentication problem as well with the
RIS service. More about that here
http://support.microsoft.com/default.aspx?scid=kb;en-us;262800.

Overall, I would say you have a server or domain controller that's
trying to communicate with the rest of the domain but it's facing
authentication problems with credentials somewhere. I've seen before
when having incorrect DNS suffix information entered on a server. Check
your server's network settings, which are probably hard coded, and make
sure you have the correct information entered, especially DNS and search
domain information.

Hope this helps! bill
