Thank you very much for that insight Stephen. I'll take a closer look at
this system. I was able to finally get it running at normal speeds
yesterday after uninstalling that MS835732 patch (MS04-011 bulletin), but
maybe there's still something on this system as you suggest.

I also had another Win2000 machine yesterday exhibit extreme sluggishness
and after uninstalling the above patch restored it to normal operation
too. Now I'm wondering what patch to apply to close the hole without
screwing up the performance of these systems. Anyone find alternative ways
to patch the exploit supposedly fixed by MS835732?
