After wrapping up an Exchange 2016 migration it was time to decommission our old Exchange 2010 server.
To do so, it is as easy as going to Control Panel > Programs and Features > and Uninstall Microsoft Exchange 2010
The uninstall wizard handles all the Active Directory object cleanup and removes the old server from the hybrid exchange group.
When running though the wizard gives the error:
Could not find any available Domain Controller in domain DC=d,DC=domain,DC=com.
This is actually a really deceptive error. After checking DNS settings and network connectivity, I thought to disable UAC.
After disabling UAC and rebooting, the wizard went right through with no error.
Thanks Microsoft! Would help if the error actually complained about permissions or something to really point to UAC being the culprit.
