After un-installing SQL Server 2005 Beta version, I started facing issues with my SQL 2000 installation and it was shooting an strange error...
SQLDMO has not been registered, please re-run SQL Server setup and contact your system administrator”.
After some analysis, i figured out that the issue was with SQLDMO.dll registration which went for a toss because of 2005 beta un-installation. To fix the DMO try running this:
Regsvr32 [SQL folder Program Server]\80\Tools\Binn\SQLDMO.dll
This brakes the registration of SQL Server 2005 dll registration...so make sure you are doing this after un-installation of 2005 beta...
