After my post on rebuilding the WMI Repository, I thought it might be a good thing to write a post on rebuilding the COM+ Catalog. It is unlikely that you’ll ever have to rebuild a corrupt COM+ Catalog, but it certainly is possible, for example when you get errors such as “Catalog Error 8008005 – Server Execution failed”.

This article by Microsoft describes the process to follow when rebuilding the COM+ Catalog. I’ve duplicated the steps here for ease of reference:

1. Rename the %WinDir%\System32\Clbcatq.dll file to %WinDir%\System32\~Clbcatq.dll. Make sure that you include the tilde (~) at the start of the file name.
2. Restart the computer.
3. Start Registry Editor (Regedt32.exe).
4. Locate and delete the following key in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\COM3
5. At a command prompt, type cd %windir%, and then press ENTER.
6. At a command prompt, type rmdir /s Registration, and then press ENTER. This is the location folder of the registration database. Note: If you have MS04-012 installed, you must now re-install MS04-012.

7. Click the Start button, point to Settings, and then click Control Panel.
8. Double-click Add/Remove Programs, and then click Add/Remove Windows Components.
9. Click Next to go through the reinstallation process, to reinstall COM+.
10. If IIS is installed on the computer, IIS creates several COM+ applications. These applications will now be missing. To re-create these applications, run the following command at a command prompt: rundll32 %windir%\system32\inetsrv\wamreg.dll, CreateIISPackage
