i took three brand new computers out of the box yesteday. All win 7 pro. first thing i did was join them to the domain. no problem. actually left them up and on the domain last night when I went home.
this AM, I had an error that prompted me to remove one from the domain and rejoin it. it would not rejoin. now, I have discovered that non of my win 7 pro boxes can join the server 08 domain even though they joined it yesterday.
I have worked DNS and it was already ok since this server has been up for several months and no issues. it's only this morning that I have this problem. all of my existing XP machines are still fine.
