I'm not sure if I can provide much useful information. This domain is in a
remote location from me and I have not been able to replicate this panic
action with any of my machines connecting to the domain. What I do know is
that this panic happens shortly after the system boots. The computers are
powered on at 6:45a.m. and logs show that the panic happens always around
6:48a.m. At this time there are many (~60+ machines) sending requests to
the samba server. It looks to me like the panic is occurring during log on.
There are about 35 machines that automatically log on with a mandatory user
profile with the documents folder redirected, this is the account that gave
the panic but the panic only happens once or twice in a day when it occurs.
