We have a Windows 2003 server running Exchange 2003 that is being monitored by NAGIOS. After applying some Exchange updates, we get the “connection refused” message in NAGIOS. The following is found in the event log:
Event ID: 2
Windows socket error: only one usage of each socket address (protocol/network address/port) is normally permitted (10048), on API ‘bind’
I’ve already tried reinstalling the client and rebooting the server to no success. Anyone have a similar problem?
