Dcdiag.exe Issues Incorrect "Topology Disconnected" Error MessagesPSS ID Number: 320063

When you run the Domain Controller Diagnostics tool (Dcdiag.exe) to test your topology, the tool may report that some servers cannot get changes.

For example, running the dcdiag /test:topology command erroneously reports indirect or transitive replication partners that are not authoritative for a container as disconnected if the testing server is also not authoritative for that container. Therefore, if a server is a global catalog server (it is not authoritative), replication partners that are also global catalog servers are listed as disconnected in the primary test listing.

Additionally, any domain controller that is an authoritative master (that has a writable copy) of a particular container, or is a non-transitive (direct replication) partner of the testing server passes the topology test and is not listed in the list of disconnected servers.

The error messages are similar to:
Doing primary tests
Testing server: THIS\THISSERVER
Starting test: Topology
Downstream topology is disconnected for DC=THIS,DC=DOMAIN,DC=COM.
These servers can't get changes from home server THISSERVER:
......................... THISSERVER failed test Topology
Under the conditions that are listed in this article, the Directory Services API DsReplicaSyncAll function generates the DS_REPSYNCALL_SERVER_UNREACHABLE error. This occurs if the DS_REPSYNCALL_PUSH_CHANGES_OUTWARD bit is set in the ulFlags parameter during a call to DsReplicaSyncAll.
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing.

Is it possible that you just installed the Support Tools from the installation CD, and there was already a Service Pack on your machine?
Go to the MS Service Pack page matching your SP level, download the support tools from there, reinstall the Support Tools.
Some of the Support Tools get updated with the Service Packs, so installing an old version on a service packed machine can have those effects.
