Just enabled Sky Broadband Shield on my connection due to my kids. Works fine but I don't want it to effect me when I'm logged onto the PC. I can just change the DNS servers to circumvent it but my kids often use the PC logged in as a different user to play minecraft while watching minecraft videos. There is no way i'll remember to manually change them so is there a clever way to change based on what user is active? I'm guessing fast user switching muddies the waters a little here.
