Losing network connection to server

Have a 2008 server that as of weds some wierd issues with exchange services not starting etc, losing access to shares and application, finally got most of that fixed but starting yesterday, i'm losing connection to the server every 2 to 5 minutes. Ill RDP into it and look around and everything looks fine, then all of a sudden my rdp connection gets disconnected for a few seconds then its right back up.  driving me nuts.  any idea where to even start.  it's the same for applications.  People will be working in a application and just kick them out.

Sounds like you might have a flaky NIC or switch port (less likely)?

Do you have another nic to try?
