Our monitoring sofware is telling us "the Domain controller diagnostic Advertising test failed with error "DC holding GC role does not advertise as GC". A global catalog must replicate inbound copies of all objects from all domain partitions in the forest before the global catalog can advertise the global catalog role."
It would seem to me that an SBS server cannot replicate to anything if it is the only server in the forest, but I cannot seem to find much about that after extensive Internet searching and a review of EE. I have verified in NTDS settings that the checkbox for GC is checked.
I would some expert verification on whether the SBS 2003 server should be advertising as a GC, and if so, how to correct this.
