2000 pro slow returning from locked state

[Rob G]

Hello again:

A client of mine has a fully (critical updates) patched
2000 SP4 workstation that has started taking 1-2 min to
return to the desktop from a locked state. In all other
respects the computer is fine. It boots & shuts down
quickly, logs out & in quickly. It runs well, apps load
normally, it is stable & virus free, & is showing nothing
out of the ordinary in the event logs. I'm stumped at
this point. Any ideas will be greatly appreciated.

Thanks,
Rob

Rob,

This is just a guess, but...

....the memory manager is a demand-page system. Pages can be swapped between
RAM and the pagefile. My guess is that while the computer is locked, some
process is actively running and the memory manager is swapping your user's
apps from RAM to the pagefile for the benefit of this app (or service, or
whatever). Eventually, most of your user's apps and settings and environment
are swapped out to the pagefile because they haven't been used for a while.

When the user unlocks the machine, all these pages need to be swapped back
in. That's an expensive operation.

I don't know how to determine if this is true... perhaps set up a remote
perfmon and log memory counters. But honestly I don't know enough about
perfmon to say which counters would be the most useful to you.
