Anyone else having problems joining domain in OS X 10.10.2?

I am (have confirmed I have rights since I can remove and join a Windows 7 box) having problems joining a Yosemite OS X 10.10.2 to the domain--I receive a "authentication server encountered an error while attempting the requested operation (5202)" no matter if I use the GUI to join the "Network Account Server" or use DSCONFIGAD command-line command at Terminal.

I was able to join two Mac Minis on 10.10.x a few months ago but I am having problems with a new-out-of-the-box Mini right now. Even tried erasing and reinstalling from a OS X 10.10.2 thumb drive.
