Hi all, I have been tasked with finding Net Filtering Software for a small network (8 machines + SBServer 2003) its a training suite so a lot of kids use it and we want the ability to block/unblock websites on individual client machines on the fly. The reason for this is when the kids have done their work we can then unblock Facebook/Bebo as a reward. I would prefer this to be done from one management console rather than having to go to each machine and block/unblock content. Are there any products out there that can do this?
