Removing the first exchange server from the administrative group

Posted on 2007-07-21

I have recently moved our Exchange Server 2003 to a new server.  I am wanting to remove it off of the orignal server.  I have done this once before (we keep adding servers as we add new applications...Exchange typically gets the new server we have), but I am having trouble this time.  Everything on the new server installed just fine.  I think followed the M$ instructions

"How to remove the first Exchanger Server 2003 computer from the administrative group"

I have made all of my replications, and then gave everything 24 hours to populate.  I also moved all the mailboxes to the new server as well.  When I take the old exchange server offline, I can send and receive internal emails and can send external emails.  I cannot however receive email from the outside until I bring the old Exchange server back online.  

I am not exactly sure what to do.  Can someone please help?

    open command prompt
    nslookup <enter>
    set type=mx <enter>
    yourdomainname <enter>

    this should show what is points too... if you tell me your domain name I can lookup what it points to as well

    by:r270ba is the domain name

    Here is my nslookup

    C:\Documents and Settings\rwilson>nslookup
    *** Can't find server name for address Non-existent domain
    *** Default servers are not available
    Default Server:  UnKnown

    > set type=mx
    Server:  UnKnown
            primary name server =
            responsible mail addr = hostmaster
            serial  = 4804
            refresh = 900 (15 mins)
            retry   = 600 (10 mins)
            expire  = 86400 (1 day)
            default TTL = 3600 (1 hour)

    Ok maybe that was a stupid question.  My MX record is pointing to my mail servers external address.  I just forgot to reroute the information at the firewall.  I still had it sending the ports to the old exchange server.  I have changed that to the right ports now, but I am still getting no incoming email....
