After using Dcomcnfg.exe to set the Default Impersonation Level setting to Anonymous, entries that were previously defined under Network and Dial-up Connections are no longer visible.
Furthermore, if you double-click desktop shortcuts that point to previously-defined Network and Dial-up Connection objects, you receive an error message that states "Local Area Connection cannot be found."
Windows Explorer uses the Default Impersonation Level setting to access Network and Dial-Up Connection objects. Anonymous access does not provide sufficient access for Windows Explorer to display details of these objects.

To work around the problem, use Dcomcnfg.exe to reset the Default Impersonation Level setting:
Click Start, click Run, type dcomcnfg, and then click OK.
On the Default Properties tab, click any setting other than Anonymous in the Default Impersonation Level box. The default setting is Identify.
After you make this change, all previously-defined Network and Dial-up Connection objects become accessible again.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
The Dcomcnfg.exe online, context-sensitive Help for the Default Impersonation Level setting is incorrect. It states that a setting of Delegate is not supported in Windows 2000, and implies that Anonymous is supported.
However, the article that is located at http://msdn.microsoft.com/library/psdk/com/cme_e2z_2jco.htm states the true position, which is that a setting of Delegate is supported in Windows 2000, and that Anonymous is not.
