I have a question. We have recently centralized our Exchange environment. I have 3 servers running server 2008 Standard. The Exchange 2007 environment is runniing off 3 servers. 1 Mailbox, 1HubTransport, 1ClientAccess. I am setting up rules on my packet shapers for outbound from corporate (the office with the exchange server) to the branch offices. I'm noticing that the exchange servers generate SMTP and DCOM traffic across the WAN. Does anyone know why Exchange needs two protocols? I'm confused as to the purpose of the DCOM traffic across the WAN.
For example - without the filters on the packet shapers, Exchange and DCOM will run at the maximum of the pipe - in this case a T1. So DCOM and Exchange (SMTP) will basically kill a remote office's WAN unless the filters are applied. That's fine - just what does the DCOM do - what is its purpose?
Also, is there 'best-practice' documentation for a centralized exchange environment with a corporation having several branch offices and the exchange all at the corporate office?
