Doh!! Don’t install DC on SQL box
Ok I did this mistake in my VPC,
I tried to make my machine a domain controller (DC) ,
But the box already have a SQL Server installed,
The SQL stopped and if you try to uninstall, it gives you this error:
The setup has encountered an unexpected error while Setting Internal Properties. The error is: Fatal error during installation.
To solve this, there is a good link I found in MS support:
