Change computer name:
netdom renamecomputer %computername% /newname:Server2012Core /userd:Administrator /passwordd /reboot:0
Join a domain:
netdom join %computername% /domain:nokitel.im /userd:Administrator /passwordd: /reboot:5
Create a new user account:
net user Operator /add *
You will then be prompted to type a password in, otherwise you can just not insert the * and no password will be set, forcing the user to create one on first logon.
Add user to group:
net localgroup Administrators /add Operator
You can of course specify your own group. To view all of the details of the recently created user, use the following command:
net user Operator
