New SfB SE won’t start

Usually I see this problem with EE pools, but in this case I have now seen it with two different SE installs.

The Problem

RTCSRV won’t start.  It just sits there for a bit, like 10 minutes and claims it is “Starting”.  Then the service status goes to “Stopped”.

Nothing in the event log, nothing shows in Powershell.  If you try to start from services.msc, it just sits there.  Nothing.

How did we get here?

A fairly locked down environment.  OK.  A severely locked down environment.  The tin-foil hat types have found a home in this place.  New install – new as in greenfield deployment.  Standard Edition installs, and before starting services for the first time, we ran the February 2017 CU into place.  All of that seemed fairly normal.

But the service wont’ start.

The Fix

Again, I usually see this with EE pools, but here is what fixed it:

Reset-CsPoolRegistrarState –PoolFqdn poolfqdn.domain.com -ResetType FullReset

YMMV
