SLOW performance over network

Strange, strange problem.
=20
Everything was fine yesterday morning, then all of a sudden any query over =
the network takes a REALLY long time to return. If I log in at the server =
console, every query is snappy-fast. There had been no changes to clients =
or server when this happened. All other networking services on the =
machine seem to be fine. Processors are between 0-3% utilization, disk is =
at 8% utilization.
=20
Server runs apache as well. There are many php pages on this web server =
that access the database, and display the results, all snappy-fast as =
usual.
=20
I still use the old MySQL Administrator GUI on my windows box. A simple =
'select * from tablename' that would return only three records takes just =
over a minute to return (although it says '3 records returned in 0.0086 =
seconds' at the bottom). I have many ODBC clients accessing this server =
as well, they all have slowness problems too.
=20
I'm stumped. What could possibly be causing this issue?
=20
Thanks for any ideas!

Wild Guess: Does DNS resolution, especially reverse dns resolution,
still work on the mysql server?

Check your auto negotiate setting on your nic. Run ifconfig and see if there
are a lot of errors.
