Hi, We built a new Exchange Server to replace the old one however the old one was a backend DC, GC, the one to replace is just Exchange and I've created a GC on new server. If I shut down the old server everything breaks. I'm not sure what the new Config server would be etc I need help :(

Thanks. We'll let you know when a new response is added.

Although you created the GC on the new server you must make sure that you transfer the FSMO roles also. check this site: Transferring FSMO Roles.

And here: Moving FSMO roles from one DC to another DC.

this should help. let us know if there are any issues.

In addition you also probably need to configure the client machines to use DNS on the new servers IP address instead of the old servers IP Address (Assuming that the old server was your only DC). You also need to make sure that DNS is setup on the new server before you can do this.

In addition to FSMO roles for a domain controller, you need to consider that you are also retiring the first exchange server in your organization. Here is a link to Microsoft’s KB article on how to do this task that must be done to make everything work properly, this KB article is numbered as KB822931.

    Hi thank you for the responses. The previous mail server was not the only DC, or DNS server. It was also not the FSMO. DNS has been configured on new server and currently all clients use 3 servers in DNS and the old mail server is not listed as 1. Im really at a loss as to why it all breaks. It doesn' break immediatly either after about 7 hours it does

    There are also Domain controller roles that are sometimes configured on them. The domain naming master, PDC emulator, etc. What Mrdenny and buddyfarr have stated are possible issues, but you'll also want to check the KB article I've added on retiring the first exchange server in your organization-- this in particular is likely your problem.

    Greatly appreciated everyone! I did miss the routing group change...other than that though I guess my problem is more along the networking side as I've shut down all exchange services on the old server and closed firewall connections from my FE to that BE. and mail still works!
