FIX: Non-Admin Windows 2000 Users Cannot Create Global Objects by Using Terminal Services

When you try to create global objects by using Windows 2000 Terminal Services server with Windows user credentials that are different from administrator credentials or LocalSystem credentials, the operation may fail. For example, when you try to insert a ClipArt picture in a Microsoft Word document, the operation may fail, and you receive the following error message:
However, you can use existing global objects by using Terminal Services.

This problem occurs because of the security changes that are introduced in Windows 2000 Service Pack 4 (SP4).

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

A security fix is introduced in Windows 2000 SP4 so that only administrators and LocalSystem users can create global objects by using Terminal Services. Because of the security fix, the Interface Remoting component of OLEDB is affected. Interface remoting uses global objects for cross-session communication between clients and servers. Office ClipArt uses the Interface Remoting component. Therefore, ClipArt is also affected by the security fix.

The security fix to Terminal Services may cause other unexpected behavior, or may generate unexpected error messages from applications that use the Interface Remoting component in Terminal Services sessions.
