My domain level is windows server 2003 full edition, I have 2 DC, one with fsmo is a windows server 2003 the other is a windows server 2008. The windows server 2008 has been upgraded from windows server 2003 a few month ago and has been working fine..
Recently isa server 2006 was restarted and didnt work when trying to authenticate
on a domain controller.
We get a message in eventviewer saying that following this logon failure,
local policy could not be applied and the computer name was undefined.
I discovered that isa was trying to authenticate on the W2k8 DC and that
this last one was refusing access to it ?
