The network administrator of a two man IT department managed a Windows 2003 domain with Exchange 2003. Their Active Directory DNS name was setup incorrectly a year ago; it did not have a .com extension at the end of its FQDN domain name. This invalid naming convention prevented them from migrating to Exchange 2010, which relies heavily on a proper DNS configuration. He didn’t want to proceed if it was possible to properly test. Flexible copied and restored bare metal images of their production servers to our virtual environment in our HOT Lab. In our lab, we experimented on these restored servers by performing the Active Directory DNS rename process. During the testing process, we troubleshot all effects the domain rename had on Active Directory, Exchange, and the member servers. We determined that the domain rename worked in our HOT Lab and we were able to successfully proceed with this procedure on their production servers.
