i moved our exchange 2007 scr DR server from outer office back to our HQ. i need to change the ip address to work on our network scheme here in our HQ. is it as simple as following this article here, even though i dont have a clustered environment? http://technet.microsoft.com/en-us/library/aa997813%28EXCHG.65%29.aspx stop exchange services change ip address/subnet/gateway/dns/etc register new ip address with dns start exchange services if not, what is there documentation that i can refer to assist me? we have one exch 07 server in production in our HQ running: Edge Transport Hub Transport Client Access Mailbox we have SCR setup with this other server that was in our remote office for DR purposes only that we have moved back to our HQ temporarily until we finalize a co-location and move it to there.

Yeah pretty much, IP changes for an Exchange server are not as difficult or as scary as people think it is. Just follow that article, and update DNS thats basically it.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
