So recently I have a fresh SBA install that failed to start the RTCSRV service.
TL;DR: if Get-CsVersion shows “Volume Licence Key Installed” try installing the latest CU.
A quick look and the RTCSRV service was failing to start.
A check in the Event logs under Lync server, showed event ID 12290. The evaluation period has expired.
So first thing, I checked that the licence key was actually installed with Get-CsVersion
Yep, looks okay. So lets try the old Lync Server fix by jumping into the installation folder at C:\sources\Setup on this AudioCodes and running msiexec.exe /fvomus server.msi EVALTOFULL=1 /qb
Great. That might be because we have a full licence.. so why does RTCSRV think we are a trial?
Let’s check the deployment wizard.
Yep that looks good, lets run step 2 again.
This fails as expected. Showing the the local CMS replica knows this machine is an SBA
Lets try a repair install in the SBA Web interface.
Nope still fails.
Okay lets uninstall server.msi reboot re-install and try again
Still no go, Just for kicks, lets try installing the latest CU
Lo and behold now the services will start.
I hope this helps someone else out as it took me far to long to diagnose.
