Hi Jamie, Marco from BBC in london. I have read your message (http://lists.cistron.nl/pipermail/freeradius-users/2005-November/048576 .html related to the error when the radius is trying to authenticate in AD and I am getting exactly the same message. "No logon workstation trust account (0xc0000199)". The article is dated Nov 2005 so I hope you have the solution by now! ;-) How did you fix the problem? I cant find any resolution on the net.
