I'm pretty new to administrating. I have a server which serves as our domain controller and mail-server (exchange 2007 version 08.01.0240.006). The OS is windows 2003 standard. The server usage is pretty high with all that stuff. That is why i need to move exchange 2007 to a brand new hardware which is running under windows 2008 R2 standard.
I'm really concerned about networking issues (MX-, PTR- records, etc.). The current server has two network connections: 1st for the internal (LAN) connection, 2nd -- for the external. Also, note that internet-connection is routed via another server which has ISA 2006 installed. Internet-server is the main gateway in our LAN for all user computers, and the mail-server has its own main gateway which is identical to internet-server's main gateway.
Could you please guide me through this task?
Many thanks and please let me know if you have any questions!
