Hi All
A couple of my servers have started getting Event ID 4231
“A request to allocate an ephemeral port number from the global TCP port space has failed due to all such ports being in use.”
Server 1: Physical Dell Poweredge R720 used as a Veeam repository. When event 4231 occurs Veeam backups stop working. Sometimes I can’t RDP to the server.
Sever 2: Physical Dell R210 ii used a remote branch DC/DNS/DHCP/Printer server. When event 4231 occurs DC does weird things such as printer server stops working.
Both Servers are 2012R2 and its started happening over the past few months
In both cases a swift reboot resolves the issue but it seems to be happening every 2 days or. So far (before I realized it was to do with port exhaustion) I have tried re-joining server to domain, trying a different NIC, updating drivers and firmware for the NIC and then recently reg keys from this server fault forum post. Nothing seems to have worked.
I have run: netstat –anob on both servers and uploaded the results to paste bin - Server1, Server2
Is there anything obvious you can see from the logs? For these commands to be effective should it be run right at the point of the event 4231 happening? I ran these commands a couple of hours after the event but with the server still in an error state/not rebooted.
Any help would be massively appreciated. Starting to pull my hair out!
