I have a few Macs that I want to join up to a Windows domain, when I join the test machine to the domain it works fine but when I reboot the computer it looses it's connection and I have to delete it and re-create it.
My Mac is called "macbook1" the domain is "lancaster.local" the Mac is running Mac OS X 10.6.1
I have performed the process described in http://support.apple.com/kb/HT3789?viewlocale=en_US and the problem still persists
