The Dcdiag.exe tool may misinterpret the site and server Options attribute settings (902843)

SYMPTOMS

In Microsoft Windows Server 2003 and in Microsoft Windows 2000 Server, the Dcdiag.exe tool may misinterpret the following site and server Options attribute settings:

Site

Intrasite replication may be incorrectly detected as disabled.
Intersite replication may be incorrectly detected as disabled.

Server

Servers may be incorrectly identified as global catalog servers.
Servers may be omitted from replication topology checks.

For example, if the Microsoft Windows NT Directory Service (NTDS) site settings Options attribute is set to 16, the Dcdiag.exe tool returns an incorrect analysis that is similar to the following:

[Topology Integrity Check,<domain controller name>] Intra-site topology generation is disabled in this site.
