I have a script I wrote to do EXACTLY what you want!!! it WILL remove a computer from a domain EVEN if there is NO domain controller available, and then you have the option to join the pc to a new domain, then it will reboot, and you are done! Let me dig it up and I will post it Monday if you reply that you still are in need of this.. I used this to change all the computers we wanted to in our district to a different domain, AFTER we had already disposed of the old domain controller.. It works great!
