repadmin /replsum - Experienced the following operational errors trying to retrieve replication information

Hi, I'm trying to promote a Windows Server 2003 on a domain with all Windows Server 2000 Domain Controllers (The Windows Server 2003 machine is intended to run Exchange 2003).  I'm following the Microsoft Article Q325379.  I used repadmin to determine the OS ServicePack and Version of the domain controllers, and all three Server 2000 DCs were identical (Service Pack 4, Version = 5.0 - 2195).  When I run repadmin /replsum to check replicatation, I get the following:

Experienced the following operational errors trying to retrieve replication information:
8453 - (Lists all three domain controllers with the 8453)

I appreciate any help I can get.

Thank you,
