Rolling Connectivity Issues to Server

I have an interesting problem.  I have a server that continuously falls offline.  But it doesnt fall off for the whole network.  Only some workstations will be unable to ping it at any given time.

I have tried a changing switches, network cables, and network adapters.  The wierdest thing is it will only appear to be offline to some people some of the time, and there is no pattern to it.

Unfortunately, this is my Exchange server, so throughout the day, I have heads popping up in various parts of the building saying they are disconnected, but the connection restores itself within a moment.

Any ideas would be appreciated.

What os does the exchange server use? 2003 server?2000 server?

if all the clients have the same errors at different times, it's the server's problem. Check the Event log for any error.

When specific clients can not ping, is the server able to ping back successfully?

Does your exchange use static or dynamic ip address?

Is there any ip conflict/ identical computer name ? ( other computer has same ip/name with the Exchange server)

Check for virus/spyware/firewall settings on the server and the in-trouble clients

Does the client ping the server by name or by ip address? do you use workgroup model? if so, NETBIOS name resolution via broadcast is not a trusted way. Use WINS or server-access-by-ip

Is the server actually going off line (i.e. you can't ping it or connect to it at all)?  Or are you getting messages in outlook like:
"Requesting data from the Exchange server..."

If you are getting the Requesting data, it usually means you have some performance problem contacting exchange.

It is actually going offline.  I am unable to ping it from the machine that has lost connection.
