I have a PC which is essential to the business as it runs our ironically named label system 'NiceLabel'. However since a colleague was too impatient to restart the machine when joining the PC to the domain it has decided that it doesn't want to join the domain… ever again!
I've renamed the PC and made it a member of a workgroup, when I try to join it to the domain it returns an error "The specified server cannot perform the requested operation" but it works for other PCs except this one.
Any ideas?

Check to see if that PC is already registered in AD. If the computer exists there, and the PC itself doesn't think it's on the domain you can't re-add it.
Just delete it from AD and then re-add it from the PC itself.
