I forgot the ask, why do you want to go this route rather than just downloading the apps on to the other machine ?

I have lost some of the key codes to use them.

In that case why not get some replacements

AVG is good and free AV
A couple of good removal tools are Spybot and Adaware

ALso an on line virus and spyware scanner is Trend Housecall

Hope all this lot helps;)

Thanks for the info! I will go the TrendHousecall route for now.

Oh, I would still like to just KNOW how to slave one PC's hard drive to another! I just want to know.

How can I slave one PC to another to do a ad/spy/virus scan with MY computer?

Since they are networked, you can map the drive of the machine you want to scan on the other PC then just scan the drive letter. Lookup Map Network drive in XP Help for details on how.
