I'm having an issue on my server running Windows Server 2003. I'm unclear what is wrong, but one theory is that when usage is high, that the memory gets maxed out. I'm wanting to monitor this, to see if it's really happening. Are there any utilities that I can install that would monitor the available memory, and when it drops below a certain threshold writes that information to a log file? I don't know if something like this exists, but thought I would ask.
