Renaming A Computer Over The Network

 

Run Netdom

So, let's say you have a computer named wrongname on domain "mydomain" and want it to be renamed to computer1 with admin account "administrator", then reboot after 60 seconds (with warning to user). You would use the following command in a cmd window:
netdom renamecomputer wrongname /newname:computer1
/userD:mydomain\administrator /passwordd:*
/usero:administrator /passwordo:* /reboot:60
That's all one line, in case you're wondering.
