Intermittent Disconnects on Network

In the middle of last week I started receiving complaints from users that they have been experiencing slow downs and disconnects from the network.  Some of the symptoms are sometimes is take a long time to open a file or print from the server, Outlook will disconnect from Exchange and reconnect 10 - 20 seconds later, Iseries Access loses it's connection to the AS400...  I believe I am having a problem with my switches (all 3COM 4500) however I cannot pinpoint where the problem is.  I have been running a continuous ping to a few clients that have reported problems and they do not appear to be losing connection.  

Any help is greatly appreciated.

if they have netflow ablility
the ping test is a basic test but

these might alos help

the expensive route would be to replace the switch but sometime that is not always a option also are all the pc's servers on the same switch if so try moving them to a different one if that is a option.

I found there was a rogue computer connected to the network that was causing all of my problems.  Someone connected a computer that was configured as a firewall and was running various services... When I disconnected the PC the problems we were having disappeared.  Needless to say, I had a pretty heated discussion with the person responsible.

I did not award points because I did not use the steps suggested.  Should points have been assigned in this case?
