For some reason, every computer on the network freezes up for a few seconds.
Each computer slows to a crawl when this happens and you can't access any
network releated drives. You can't open up My computer to access local
drives because the mapped drives prevent explorer from opening.

Any ideas on what this might be?

What can I do to investigate the problem?

Thanks,
Jasper
 
Since you've provided virtually nothing in your question that points to
an answer, here's my guess: malware.

Any hints in the Event logs? As that might be able to tell you what is
causing it. Also the Task Manager under the Processes tab will tell you
what is eating up all of the CPU time.

Hello Jasper:

You need to tell us a great deal more about your network's topology.
The more detail you give us the less speculation on our part. At the
absolute minimum of information, how many computers?

Do all systems experience the trouble simultaneously?

What is the one single common LAN component that all systems depend
on? Router? Server? An infrastructure cable?

Please post a follow-up that's generous with its details.
 
Our network consist of 70 plus users. We have 2 switches pluging into our
main switch where our servers are connected. We have 3 main servers, a
file/active directory server, mail server and ERP server. There is also a
few small fucntion servers such as print server, antivirus server, etc..

I have looked at the task manager and no resource spikes at all. I just get
a 99% on the system idle process.

I don't see anything in the event viewer that looks abnormal except for
event ID: 4226. "TCP/IP has reached the security limit imposed on the number
of concurrent TCP connection attempts."

I only see this on my computer but I will check others.

I don't see any spikeon the networking tab in task manager either.

Hope this helps!

Any ideas?

Thanks,
Jasper
 
Is it a 2000, 2003, 2003 R2, 2008, 2008 R2 domain? DHCP or static?

You said 'network', not workgroup or peer-to-peer. Many users use the wrong
terminoligy

If you're on a "network" not a few machines joined together with a layer 1
switch/hub then DNS is a possibility

Where are your shares pointing? Shared or network printers

Like one of the other users said you have not provided any information that
is helpful
