Username/Password required on Windows XP

Hmmm…Haven’t got a ‘Net & Sharing’ in my Control Panel. You sure you talking about Windows XP Home and not Professional ?? Only way I’ve ever gotten ‘Sharing’ to work is via Twonky & TVersity. The former is to be paid-for (albeiet very cheap) and works fine for everything. The latter is free but I have trouble playing .mkv videos with it.
