I have an issue where Exchange 2003 is showing 2 queues for each routing group connector on 2 of my servers. All of the other servers seem to show only one. When I renamed a routing group connector, I got two queues with the same (new) name again. I deleted and recreated the routing group connectors between the two cities and got 2 queues showing again. I used an SMTP utility (sorry forgot which at the moment) which also showed duplicate queues. I don't have any symptom directly related to having duplicate queue names, but i do have one of the servers which will occasionally stop sending SMTP till restarted. While researching it, I noticed the duplicate queue names and thought I'd ask if anyone else has seen that.
