Rebuild Windows COM+

If you are getting corrupt COM+ subscriptions, this is shown by being unable to do anything then follow these steps to resolve your issues

1. Rename the %WinDir%System32Clbcatq.dll file to %WinDir%System32~Clbcatq.dll. Make sure that you include the tilde (~) at the start of the file name.

NOTE : If you get "File in Use" complete this operation from DOS

2. Restart the computer.

3. Start Registry Editor (Regedt32.exe).

4. Locate and delete the following key in the registry:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftCOM3

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.

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+.

NOTE: If you get a error about cannot talk to COM+ / Distribution Server then...

9a. Goto Commnd Prompt

9b Enter %windir%system32

9c msdtc -uninstall

9d msdtc -install

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%system32inetsrvwamreg.dll, CreateIISPackage

If Windows File Protection blocks the renaming and deletion, restart the computer in Safe mode, and follow these steps again.
