How can I unjoin a computer ?
you can simply remove the computer object in the UMC computer module.
Thank you Tim !
I have done that, but after i reinstall the server when i try to join the slave again i get error that the mac address already exists...How can i clean the remaning information of old server?
I don't know but you are right, they stay some trace of old slave computer.Actually I have some issues to install application after delete the slave and rejoin the slave.it's will be good to have a kind of clean up script.
