I created a new VMware server from a template, the template was on the domain and had been used for a prior server. That prior server is a current production server. When the new server came up and was renamed Active Directory lost the previous computername. Is there a way to restore the computername of a production server to Active Directory as assigning a new IP is not viable at this time?

To make sure I understand correctly:  You brought a new virtual server online that was a clone (created with P2V tool or some similar) of what's now a production server then renamed it?  As long as the production server is not a Domain Controller, Exchange Server, or some other type of ACtive Directory integrated server the fix is fairly simple as follows:

1.  Make sure your virtual server no longer has the name or IP address your production server needs
2.  Log on to your production server with the local Administrator account (or some other local account that's a member of the Administrators group)
3.  Go to System Properties:  Start > Settings > Control Panel > System
4.  Go to the Computer Name tab and hit the Change button
5.  Change Member Of to Workgroup, enter "Workgroup", then hit OK
6.  Reboot the computer when prompted
7.  Log back on as Administrator and go back to System Properties > Computer Name > Change
8.  Change Member Of to Domain, enter your domain name, then hit OK
9.  When promted enter credentials of domain account with right to add computer to domain (member of domain admins group)
10. Hit OK on welcome to domain message then reboot when promted
You should be set now.

Thank you much, that was my initial plan but I was concerned that DNS would fight with me unless I changed the ip, however this worked fine. Again thanks!
