If it's just a few websites, make them point to 127.0.0.1 in DNS.

Add a entry on hosts file as follows:

dns.name              any IP

For example:
www.yahoo.com             74.125.230.84

This line redirects www.yahoo.com to this ip (google).

Hi Drashiel,
u r right, can be done above, problem is there are some clients which are not joined to domain..how about for them ? But they still use server DNS. The above option applied to member of domain only.
Any suggestion for setting ? Or simple open source tool to run in server ?

You have a firewall of some sort in place?
You might be able to do some blocking from there.

bominthu, block messenger software has no big impact, because are a lot of webpages that has web messenger. Squid or Forefront could block using categories to filter this traffic.
