Server 2003 network slow down.
I have a client who's network just all of a sudden slowed down between the server adn client machiens (File transfers, outlook..etc.).
They are in a server 2003 environment.
The domain controller is also the exchange server.
There is 1 terminal server server
There is 1 ISA server
There are about 80 or so clients on the netowork all running XP pro.
I check the event logs on the DC and nothing sticks out. I checked the network usage and nothing sticks out. The servers are all dual core/ doul xeon machines so there should be enough power. I can ping the DC adn the other servers no problem and I can get to the shares with no problem, but moving files is slow.
I checked DNS - look ok. I flushed the cache and re-registered. Tryed rebooting the system. Nothing
I have now Idea where to start with this.
I was going to set up just t 1 machine with the DC and go from there.
any suggestions would be helpful.

switches try to fail gracefully. Our gigabit switches fall to 100 when a variety of things occur, then they fall down to 10 as a last resort prior to shutting itself down. All the while, its spitting out error messages and trying to tell you something is amiss.
When multiple servers are all having a similar problem, remember to check the networking equipment too!

They are using 3 24 port switches. One is a Dell ppower connect managed switch ( although I never configured it). The servers were pluged into the dell switch and I noticed that some of the connection lights from the client machines were orange on the left and green on the right of the connection to the switch and some were green, green. The ones that were green and green ran great adn the ones theat were orange and green ran very slowly. When I plugged the servers into one of the other swiches everything seemed to run fine again. Is this some kind of duplex thing? I just don't know too much about it.
If I'm not making sense please let me know and I will try to explain it better. I would really liek to know what happend and why.
