hii, what cloud be the correct and microsoft recommended scenario to installing the exchange 2007 with domain controller. Shahulhameed

Not sure what you are asking, but it is not recommended to install Exchange on a DC.

hi andy, see i have DC1 and additional DC2, here can i install the exchange 2007 in dc2Shahulhameed

You can, but its not recommended. http://theessentialexchange.com/blogs/michael/archive/2008/03/29/exchange-server-2007-and-domain-controllers-a-summary.aspx

That's a bad scenario, especially if you will deploy a public facing CAS server

hi, agree with others, installation of exchange server 2007 on domain controllers is not recommended. but in the production there are too many exchange servers are running on the domain controllers. installation requirements for exchange server 2007 ; http://technet.microsoft.com/en-us/library/aa996719%28EXCHG.80%29.aspx regards, Mumin CICEK | www.cozumpark.com
