We've multiple servers running on Server 2003 Standard edition with SP2. On one of our DC, we keep receiving the following error messages. When it happens, replication stops and automatically resumes after several minutes. All DC's passes full DCDIAG and NETDIAG tests.
When I ran netstat command, I can see several ports were opened by an unknown process with process ID 8096.
90% of our other servers and workstations point to this server! Is there anyway to troubleshoot and identify which process is not releasing proper ports?
Any further help would be greatly appreciated. Thank you!
Netstat result sample (the bellow process displayed more than 100 times with different local port)
Proto Local Address Foreign Address State PID
UDP 0.0.0.0:49160 *:* 8096
There are no more endpoints available from the endpoint mapper. (1753)
The RPC server is unavailable. (1722)

I suggest you check replication errors using repadmin/failcache /v & dcdiag/test:replications commands based on the errors we have different troubleshooting steps. The below useful links are for your information.
