4GB RAM

What follows is a loose log of what I've been experiencing and what I've
done. What I find interesting is that it's ALWAYS Xhours to the minute
when the exchange service starts generating errors.

I did try the /3gb switch even though it's not Adv. Server, but it did
not help nor worsen the situation. I have long since shut it off.

Before /3gb
