Back-End to Front-End Queue
Please help! I have just taken on some Exchange responsibilities and am struggling with anExchange issue I've inhereted... I have two back-end Exchange 2003 clusters thatforward their email to a front-end server. One of the back-end clusters never has any messages sat in the BE-to-FE queue, whilst the second cluster regularly queues email messages. Even when it is apparently idle messages on the BE-FE queue can sit there for hours. Oddly, it is the busier of the two exchange servers that works properly. Any help would be greatly appreciated.

Hi, Which one did you assign the bridgehead ? This is the one who sends mail to the outside world. Can you confirm you have and active-active cluster ? Regards, Johan blog: www.johanveldhuis.nl

Sorry guys.. this is a bit embarrassing. Despite our network engineers telling us that everything was clear on the switch, it turned out that the port had been set to 100Mb half duplex instead of 100Mb Full duplex. This was causing lots of transmission delays and therefore messages to build up on the backend-frontend queue. Sometimes it's the easiest things that get over looked. Thanks for the replies and sorry to have troubled you.
