Tried to start Microsoft SQL Server Enterprise Manager and got stuck at the error message General OLE Error 16386:

try this, maybe this solves the issue..

a. Stop all SQL Server services (MSSQLServer, SQLServerAgent, MSSEARCH)
b. Open command prompt and go to the %ProgramFiles%\Microsoft SQL Server\80\Tools\Binn directory
c. Unregister the following .dll files (Ex. regsvr32 /u dtsui.dll): dtsui.dll,sqlns.dll, sqldmo.dll, sqllex.dll, sqlmmc.dll
d. Copy and paste the .dll files from a CD (under x86\Binn directory) to the Program Files\Microsoft SQL Server\80\Tools\Binn
e. Register the .dll files (Ex. regsvr32 sqldmo.dll)
