I recently had a failed Exchange 2013 uninstall on a standalone CAS server called #3. The failed uninstall in turn refused to re-install so I was stuck between a rock and a hard place so to speak.
After long hours of coming to a decision on how to proceed i plucked it out of AD using ADSIedit.msc. If you are curious I only removed the problem server from Servers inside of Configuration for our main DC.
Now, life is good. No issues, exchange is very happy.
My question is this, I need to reinstall exchange on this Gen10 server, can i re-use the same problem server name or will i have issues?
This is what i did to remove it entirely. I feel like im forgetting something else i did but i do remember doing all of these.
Removed from all Exchange Member of groups. Trusted System etc.
Removed from Servers list in ADSIedit
Botched uninstall which removed about half of exchange.
or should i name this CAS4 and move on with my life?
