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

This article has been archived. It is offered "as is" and will no longer be updated.
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:

  • Intrasite replication may be incorrectly detected as disabled.
  • Intersite replication may be incorrectly detected as disabled.
  • 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.
This problem occurs because the Dcdiag.exe tool incorrectly translates the Options attribute for the site NTDS site settings and for the server NTDS site settings. These two attributes are both single-digit integers. When you set the Options attribute to 16, you obtain the same result as when you set the attribute to 1.
