  • Nothing happens when you right-click a hyperlink on a Web page, and then click Open in a new window.
  • You select a hyperlink in Microsoft Outlook or Microsoft Outlook Express and it does nothing.
  • In a drag-and-drop operation, when you attempt to drop an item to the Start menu or any folder on the system, the mouse cursor changes to a circle with a slash through it and it does not enable you to drop anything.
  • In Microsoft Internet Explorer, on the
    Edit menu, when you click Find (on This Page), it may not work or it may only work once.
  • If you point to Search, and then click
    For Files or Folders, it does not work.

    Problem occurred using Office Assistant, Do you want to reinstall it?

    Cannot create another system semaphore.
  • You cannot print from in Internet Explorer.
  • You cannot print HTML messages in Outlook.

Note that this functionality appears to fail in Windows Explorer and Microsoft Internet Explorer.


This behavior may occur because the Default Access permissions have been changed in the Dcomcnfg.exe tool.


To resolve this behavior, perform the following steps:
  1. Click Start, click Run, type dcomcnfg, and then click
  2. Click the Default Security tab.
  3. In the Default Access Permissions box, click Edit Default.
  4. Verify that both System and Interactive are listed with Allow Access. If either are missing, add them by clicking
  5. In the List Names From box, make sure that the local computer name is listed.
  6. Set Type of Access to Allow Access.
  7. Click the account that is missing, and then click
  8. Repeat Step 7 if both accounts are missing.
  9. Click OK, click OK, and then click OK again.
To update your settings, you must log off, and then log on to the computer.

More Information

If the list of Access permissions is empty, the system and interactive accounts have implicit access rights. If a user or group is added to this list, the implicit rights no longer apply and only the users explicitly listed can have rights. This is a change in behavior from Microsoft Windows NT 4.0. In Windows NT 4.0, the system and interactive accounts maintained their access rights even though they were not explicitly listed.For additional information about related topics, click the following article number to view the article in the Microsoft Knowledge Base:
