I agree 100% with Ekhaatvensters.XP SP2 is full of bugs and its bloatware. Install Vista.
My printer had a similar problem during the install, the detection always seems to have problems. I think a reset or cable switch also did the trick as with Killa.
Xp with SP2 has been a nightmare since release.
So many people 'upgrade' to SP2 then anything to do with network detection sucks also their PC slows down by as much as 30% and later they go out and buy faster PC's and put Xp SP2 straight back on again !
Either use Vista although that sucks too, or Install Xp SP1 and go get the SP3 Beta and install that as it a 100% better.
SP1 only has one problem in that it struggles to see some USB sticks and of course if you are an IE7 fan you're in trouble but that sucks also, hence IE8.
