To fix these problems:

3. Expand Component Services.
4. Expand Computers.
5. Right-click My Computer and press Properties.
6. Select the Default Security or Default COM Security tab.
7. In the Default Access Permissions area, press Edit Default.
8. If either System or Interactive is NOT listed with Allow Access, press Add to add them:
Select the local computer name in the List Names From drop-down box.
Select Allow Access in the Type of Access drop-down box.
Select the missing account and press Add.
Press OK, OK, Apply, and OK.
9. Log off and log on.
NOTE: If the list of Access permissions is empty, both System and Interactive have implicit permissions. When you add an account, implicit rights no longer apply, as they did in Windows NT 4.0.
NOTE: If you installed the Office 2000 SR-1 Update and you experience similar problems, download and apply the o9regfix.exe fix.
