Changing Windows 2008 R2 Server Hostname
We are running Windows Server 2008 R2 Enterprise and have joined the server as a member server to the domain. We would like to remove the server from the domain and rename it. Then re-join the server back to same domain. Can we do this without having to rebuild the server from scratch?Can we use the same computer object in AD, or should we delete it and have it re-created during rejoin? There has always been disagreement in our shop about need to rebuild from scratch. Some say only when server is DC. Others say always rebuild it. Thanks in advance!Bill

1. Can we do this without having to rebuild the server from scratch? No need to rebuild the server, just remove it from the domain, reboot and join it back to the domain. 2. Can we use the same computer object in AD, or should we delete it and have it re-created during rejoin? No need to delete computer account, active directory will reset the account when you rejoin the computer o domain. This is standard AD activity hence no need to be paranoid. :) Sachin Gadhave (MCP, MCTS)

Hi All, Also if you have Dyanmic DNS or AD based DNS in your environment then, no need to register in your DNS entry also. Again for verification purpose, kindly get into the nslookup cmd, try to ping for the server IP; verify whch host FQDN it get resolves.
