Hub Transport server Priority - 17.Oct.2011 5:19:27 AM

Newbie to the forum.
I have a question about Hub transport Servers in exchange 2007sp2. I have just started at a new company. They have an exchange 2007 org with the following servers. 2 x CAS/HUB in NLB, 4 x DB servers in 2 x cluster mode. 1 x server with all roles installed which they call the test server. I had a problem with installing a new version of AV on the �test� server as it had an option enabled to detect mass mailing worms and blocked the test server from sending mail and caused a queue of 17,000 emails. I appreciate that a test server should be in a sandbox but in this current situation is there a way to stop the DB servers using the test server Hub Transport, or stop this Hub Transport instance from picking up internal mail, as I know internal mail flow doesn�t use connectors?
Many thanks
Gavin

When monitoring servers running Microsoft Exchange Server 2007 with the Hub Transport server role installed, you should know which performance aspects are most important. Hub Transport server operations are primarily CPU and storage (disk) intensive. The CPU is used by the Hub Transport server, edgetransport.exe process, and the antivirus processes. The Hub Transport server needs CPU cycles to process messages and perform operations such as content conversion and message bifurcation. Antivirus processes that scan each message can, at times, consume more CPU and memory than any other process. The performance of disk resources is also important as the Hub Transport server role processes copy mail out from memory into the queue database.
