you can use any firewall for this purpose like ISA server. Or if you want to just block sites on a single system then you can do this as shown in the link
to manually add applcations like GTALk you have to give there application address like following
Block these IP's for GTalk

Block these IP's for MSN Messanger: - -
and the IPs

what you have to do is just put these ips and web addresses into host file as shown the link above.
For further you can use following as well

hope this will help you
I'd recommend Windows Steady State like mop_se said.

Another two options would be something like OpenDNS ( or if you want it to be server controlled, Untangle Web Server (

Depending on your network, if you have Exchange? you can configure RPC over HTTP using SSL and then you can control access to the internet using a proxy server. You can configure the proxy via your Router/Firewall.
