So here is the dilemma, which i honestly have been on for the past month, and can't seem to track down the issue. It hasn't been just me either, there was a support case from Microsoft created, and they can't seem to figure this out either, so if i get no replies here i understand why. (open to suggestions)
The issue is that the Domain logon server itself is disappearing, which in a high load environment i would understand and think this is likely an issue with over utilization.. The environment here is 34 people, and at any given time there is only 20 - 25 in the office. But, for whatever reason, i am getting clients disconnecting from the domain controller. I had created a Domain policy to try to force the systems to wait for the network, thinking this would at minimal point out if this is a network issue, or a server issue.. But the Policy setting doesn't seem to make a difference.. (Wait for network and require domain controller to log into the PC)
