Problem with Network Connectivity?

We're having a problem with network connectivity since our FMS 3.5.1 server has went live.  When this happens the server does not deliver the flash content until it is rebooted.  Any suggestions?  We're this is our first FMS and we have no clue on how to resolve this issue.
