New install on an old Dell GX270
I added a a nic card to the integrated nic on the motherboard.
It's a Pentium4 3.2ghz workstation for testing.
I'm running in Bridge mode.

Looks good but right after bringing it online, users who are accessing database outside of our LAN over the WAN to another department lose connection and have to sign in again on the remote DB and non committed data is of course lost.
Some users are also losing connection to our Exchange Server and can't send email until it mysteriously reconnects. Exchange is hosted in another Domain with the proper trusts in place.
I ruled out trouble on the DB and Exchange side by unplugging the UT box. All problems vanished until I reconnected it and brought it up again.
All other network access works fine as well and internet access. It's just these two connections to other networks for our DB and Email.
I have Web Filter and App Control apps running with default settings. All other apps are off.
Any ideas why I would see intermittent drop offs of connections?
