[K12OSN] Users randomly logged out?

[David Hopkins]

 This is on 2 different servers with different hardware.  And three
different types of clients. None of the clients have gigE connections.
I haven't had a chance ot get over to the school yet to try different
accounts.

I am using Amer.com switches primarily though I have some older
Netgear switches as well.  The school had a power hit the other day
(lightning storm) but all the switches are on UPS and never went down.
 Clients were on both types of switches.  Simply connecting 2 of the
thin clients to a different server stopped the issue. Those clients
were originally on the same server which is handling 40+ other systems
without issues so it could be an issue with the dhcp database being
corrupted somehow.

I'll go in to the school this weekend and experiment with different
hardware and accounts from the various locations that these clients
are located.

Thanks for the suggestions ... it gives me something to test.

Sincerely,
Dave Hopkins
