In our Exch2007 environment, we used to have 2 NLB Client/HT servers, but when that started having problems, we broke the LB connection and pointed the IP straight to the working transport server. This was also due to us exploring other LB methods, such as a hardware solution. However,I had to add a 3rd tranport server to the mix for some testing. I didnt give it any recieve connectors and didnt add it as a possible send connector either. I thought this would be enough for Exchange to send messages through the working servers, but apparently not, as this caused a backlog of queued messages on the server, which I didnt notice till later in the day. In a situation like this, when there are multiple tranport servers, how does Exchange decide which one to use? Does it have any sort of load balancing in place already for internal and/or external messages?Edit:Another question...I have 1 resource domain where Exch is installed but one of the child domains is production and the other is for testing. Is there a way for me to run loadgen with traffic separation, so that all loadgen mapi traffic to/from the different mailboxes is routed through just one of the client/transport servers?

btw, is there a way to get queues from multiple servers with one get-queue cmdlet?
