How can I rename Windows Server 2008 Server Core
Once again, with no GUI your Windows Server 2008 Server Core can easily be renamed using Windows Management Instrumentation Command-line (WMIC), and here is how,
wmic computersystem where name=”%computername%” rename name=”new-name”
As result, you will get ‘Method execution successful’ message. However if your machine is domain-joined, you can use NETDOM to accomplish the same task. Here is the query.
Netdom renamecomputer %computername% /NewName:new-name /UserD:domain-username /PasswordD:*
