Unresponsive server

I have a server that is running Windows Server 2003 standard edition(Server1).  It is configured as and AD DC and also provides the following services:  DNS, DHCP, and simple file sharing.  On my network I have a total of two DC's and around 100 workstations that all run Win XP Pro SP2.  

My issue is that occasionally network performance becomes really slow.  This results in very slow access to files stored on the network and slow logon times for all of my workstations.  I can resolve the issue by restarting Server 1.  After a reboot performance is back to normal.  I can find nothing in the event viewer that indicates what the problem is.  I also do not see anything out of the ordinary in any of the performance monitors that I have configured.  

The problem is obviously on the server, but I am at a loss of what the specific problem may be.

How many NIC cards are you using?  Are you using switches or hubs for your network?  What is the speed of backbone?

The server has two NIC's installed.  Only one is used and the other is disabled.  I am using swithces on my network and all servers are connected via 1GB network connections.  The worksations are either on 100MB or 1GB network segments.

what's the actual server's performance like? I.E. normal operational speed when logged on to the server at the time when network access is slow?
I think jdera is maybe referring to a NIC driver update recently instlled causing problem...in any event the quickest check is to disable current card and enable the disabled one, configure it same as pevious and see how that works.  Cnange your ethernet cable :)

OR

change nic auto negotiate rate to 10/100 full duplex see if that sorts problem.

Also, at network slow times check CPU useage on server especially if you have scheduled tasks like Anti Virus scans.

Finally, check DNS on both DCs...not likeliest but poor DNS resolution can affect file replication, RPC, netlogon, AD, Group Policy, propagation and all sorts...check DNS event logs.  How does DC2 respond when network is slow? Ideally DC2 should be preferred DNS entry and DC1 should be secondary on the active NIC of DC1.

Performance at the server console appears to be fine when network access is slow.  At times when  I get to the point of having to reboot the server seems a little slow to restart.  

It also  appears that this issue may be getting worse as it now appears that it is taking my workstations longer to log onto the domain.  Obviously the DC in question is involved in processin those login requests.

sorry I'm not sure if you're still having this problem, I note from your last post that the problem is getting worse, I also note that you didn't comment on disabling/changing nics...I was wondering if you had tried putting in a new NIC I.E. open server install brand new nic?  Have any new problems arised since your last post?

BIOS update on the server seems to have resolved the issue.
