I've been trying to fix this for a few weeks now but we occasionally get no logon servers on some of our computers.
Not always the same computers and a rest normally fixes it.
It started after our PDC crashed beyond repair and i had to build a new one and reclaim all roles etc on the secondary DC.
I have reimaged the computers in question in the hope that it was something stored locally on the machines but this hasn't fixed the issue.
I'm hoping someone here can point me in the right direction for tracking this issue down as it's starting to grate.
Any help would be greatly appreciated!
