When you upgrade your computer to Microsoft Windows 2000, you may find problems when starting the Component Services snap-in from Administrative tools, or you may notice problems when trying to run ASP pages.
When you open the Component Services Microsoft Management Console (MMC) in Windows 2000 and click to expand the Component Services and Computers nodes, you may receive the following error message:
This problem usually happens if there was a problem during COM+ setup.
This behavior is by design.
At the beginning of setup, Windows 2000 generates a file named ~clbcatq.dll. The existence of this file signals that COM+ setup has not been successfully completed. When COM+ setup completes successfully, it deletes the ~clbcatq.dll file.
Check whether the ~clbcatq.dll file is present in your %windir%\system32 folder. If so, then it's likely that something failed during COM+ setup. If the ~clbcatq.dll file is present, this could be because either:
- The Windows 2000 optional component setup experienced some problem and halted prematurely, before allowing COM+ to finish its setup. -or-
- COM+ setup experienced some problem.
Windows 2000 uses ~clbcatq.dll to determine whether or not to allow access to the COM+ catalog. If this DLL is present, then you can't use the Component Services snap-in to administer the COM+ catalog, and ASP pages and ISAPI DLLs will not run.
Problem Diagnosis and Troubleshooting
COM+ setup logs errors to a file named Comsetup.log. Search Comsetup.log for errors.
If you find COM+ errors, follow these initial troubleshooting steps:
- Delete the ~clbcatq.dll file.
- Move the contents of %systemroot%\registration somewhere else
- Export the HKLM\Software\Microsoft\COM3 for posterity, then delete it.
- Re-run COM+ setup. To do this, follow these steps:
- In Control Panel, click Add/Remove Programs.
- Click Add/Remove Windows Components.
- Click Next several times, and then click Finish.
If this method does not correct the COM+ setup error (for example, COM+ setup fails again), collect all the error messages found in Setuperr.log, Comsetup.log,
NOTE: Make sure that the identity setting of the IIS Out-of-Process Pooled Applications in component services is set to IWAM_(Computer name) after COM+ setup has finished successfully.
