After having both the PC's back home, reinstalling software, getting them to network, all is just about ready to go once more. And you wouldn't believe the amount of trojan crap on the PC that wouldn't work properly 
The worst one was fresh-weather, a thing that makes all your Google searches go off to some rather "unusual" sites, lets say. And, despite using just about every available spamware, it wouldn't go away, having buried itself deep in the registry. A complete reformat and install put paid to that though, and with lots of other things not working properly, it was the cleaniest option. 2 clean, shining, working PC's sit in the office now, all networked, and printing to the fantastic Brother MFC-440CN colour printer/fax/scanner Ian got for a song (top buy there bro 
)
A few little things left to install, but I'm going to do that tomorrow morning. It's time for beer
