I have installed a new Windows Server 2008 server (domain controller) with SQL Server 2005. Then I had to change the domain name and ran into problems with SQL Server. It would not start easily and it could not be uninstalled.
I got the following error message: "The setup has encountered an unexpected error while Setting Internal Properties. The error is: Fatal error during installation." and in the setup log files I found entries like "
After a long search I found the solution in the Microsoft Knowledge Base, articles 919945 and 925976. It boils down to emptying four registry entries in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.2005\Setup or HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL.X\Setup:
- SQLGroup
- FTSGroup
- AGTGroup
- ASGroup.
Do not delete the entries! Just empty them.
Then I could uninstall SQL Server.
Be aware that you might not have all mentioned groups. It depends on the features of SQL Server that you installed.
