Intel Pro/1000 GT – Periodically stops passing traffic - Why?

I have a BioStar MCP6P M2+ Motherboard (AMD) and an Intel Pro/1000 GT Gigabit PCI Ethernet adaptor.  Periodically the NIC stops trafficking packets.

The interval between failures appears random, could happen twice or more in a day and then not for a couple of days but whatever the trigger the result is the same:  The Intel Pro/1000 GT network adaptor stops passing traffic.

The Intel Pro/1000 GT network adaptor shows as being connected but using ping results in 100% loss.  Disabling and Re-Enabling the interface corrects the problem for a while.

This problem has been going on for a couple of weeks now.  I have tried removing the device and re-installing drivers (Device Manager Hardware) all to no avail.  I have also enabled/disabled the on-board 100mb NIC but it appears to play no significant role in the problem.
