The ISearchTech.ysb file is evidently a leftover
registry entry from AOL Toolbar for IE. The
toolbar itself has been uninstalled, but the
registry entry is still there. I was unable to
remove it, but the system is no longer throwing
errors and memory usage seems normal.

We may still need to ghost this machine or maybe
install more memory in the future to avoid these
types of problems. The librarians seem to like to
run a great many programs at once as well as
remote desktop connection to their regular office
machines.

Heading over. Evidently making sure that system
files are shown then rebooting into safemode and
scanning with spybot is supposed to remove this.
I'm going to try that again and see if I can get
anywhere with it.

Task reassigned to Michael Orr.

She is working at the Reference desk currently 
and can be reached at 88881. After clicking 
through error dialog boxes, she can still acess 
some applications, like IE, but none of her 
network drives are mapped. She is also not able 
to remotely connect to her office PC from this 
computer: "Unable to connect, low virtual 
memory." But when she remotely connects from a 
different computer, all is well.
