In Windows XP and Windows 2000, you may have a problem opening the Computer icon in Component Services (Dcomcnfg). When trying to open it, instead nothing happens and it automatically closes the entire window and disappears.

Try the following things to solve this issue.

1. Click Start > Run and type regsvr32 ole32.dll and click OK.

Try it now. If it doesn’t work, go to step 2.

2. Click Start > Run and type regedit and click OK.

3. Navigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\COM3

4. Delete the COM3 folder. Close the registry editor.

5. Open Start > Settings > Control Panel.

6. Open Add/Remove Programs.

7. Click Add/Remove Windows Components.

8. Click Next through the wizard. No need to check anything first. You may be prompted for a Windows Installation CD.

9. Restart the computer and try Component Services again.

If that doesn’t work, you may want to explore certain programs that may have corrupted this option. Some have reported that uninstalling McAfee or Nero products have fixed the issue.
