Sql2008-c:\progra~1\common~1\system\oledb~1\oledb32.dll Error Unable to find the specified module

MSSQL2000 cannot query data in Enterprise Manager

SQL Server cannot execute the query because some files are missing or not registered to solve the problem
It is not possible to query the data directly in Enterprise Manager, but it can be viewed with the Query Analyzer and it is useless to reload the SqlServer2000.
Workaround: Register the following four DLL files
regsvr32 "C:\Program files\common Files\System\Ole DB\Oledb32.dll"
regsvr32 "C:\Program Files\Common Files\system\ado\msado15.dll"
regsvr32 "C:\Program files\common Files\System\Ole Db\sqloledb.dll"
regsvr32 "C:\windows\System32\Atl.dll"
or
regsvr32 c:\progra~1\common~1\system\oledb~1\oledb32.dll
regsvr32 c:\progra~1\common~1\system\ado\msado15.dll
regsvr32 c:\progra~1\common~1\system\oledb~1\sqloledb.dll
regsvr32 C:\windows\System32\Atl.dll
solve this problem. But on the Internet, there are the following possible, but I did not appear

When the registration is complete, the provider is not found. The program may not be installed correctly "prompt. Again, we need to register the components:
regsvr32 "C:\Program Files\Common Files\System\Ole Db\msdasql.dll"
After registration, the Enterprise Manager query again appeared "No registration category" error, it seems that the system's database access components have a problem, root cause in the system installation, MDAC may have lost the relevant files, then reinstall it:
Into the C:\WINDOWS\inf, find Mdac.inf, click the right button installation, follow the instructions installed, you can finish.
