I'm sure we could just guess all day about this, but perhaps you can enlighten us a bit more about how things are setup, what you have done to diagnose the issue, when did this start, did you make changes to something and then have this start? If you provide clear information, perhaps the experts can help.

Connections to the AD and exchange are very unstable, we have the latest AV updates (trend), switches are ok, etc... Any clues?
