Gee - Thanks for all the great suggestions so far!!
I have turned off power management for the adapter as instructed, but
as i can not re[licate the problem at will, I will just have to wait
and see.

They are listed.

I am running an Asus A8N32-SLI Deluxe motherboard with a AMD Athlon64
2.2Ghz 3500+ chip. The twin onboard (motherboard) ethernet adapters are
Marvel Yukon 88E8053 Gigabit Ethernet Controllers.
Under power management for these adapters I have unchecked the setting
"Allow the computer to turn off this device to save power"

Will try that next time it does it.

It varies, but the average would be twice.

Thats a interesting point - because it has been happening in the
mornings, but also happens overnight (I am not on my computer but my
MSN is logged out suggesting a loss of connectivity)

It has happened when I am using it, and I am pretty sure it has also
happened when i am not.

Good suggestion.

Another good suggestion - will try that too.

Someone else mentioned Malware/Virus? I thought about that too - I have
had my HiJackThis log checked over at CastleCops- and I am clean. Also
running Ewido and Kaspersky - all clean.
