Actually it was planned for this server to be a member of DAG and should be with the same naming scheme as of the other DAG servers.

Just user add/remove program to remove the Exchange server. Once all roles are removed. It is now a member server in a domain, now rename your server. Restart your server. Verify if it is registered properly in DNS. Run nslookup and ping command to confirm.<br />
<br />
Now, install Exchange server on this server again with Rollup. Make sure you are using same service pack and roll up installed on other server. No higher version.<br />
<br />
Let me know, if any doubt.

What next?<br />
<br />
Either you recover this server again, with recover switch and then remove it again. Which is the recommended way. I hope this is not your first Exchange server, else steps will be bit complicated to remove it.<br />
<br />
If not a first Exchange server, we can clean this up via adsiedit also.

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
