RUS "error" ???

[novachild]

Fairly in the dark here. Need some assistance.

I'm in Exchange System Manager :: RUS. Two instances appear, one for the local domain and another for "enterprise configuration." Both are pointed to the same DC, but when I click "Browse" on the first instance (NOT the Enterprise Configuration), I receive this error:

Only one instance of the Recipient Update Service can update a domain controller and all domain controllers on 'bfluti.local' are already beign updated.

I've gone through this article:

I don't appear to have a disjoint namespace.

So is this a normal 'error?'

This may or may not have anything to do with a subsequent post on this forum. Thought I'd better play it safe and consider it a separate incident.
