Possible to restrict internet to only 2 websites?

Hello, is it possible to restrict internet usage to only 2 websites? Is there any software I could buy, or specific settings I could change on the computers to do this?  I literally only want my employees to access 2 websites, and nothing else. We have 15 computers on a Win2003 domain. Thanks!

You could remove root hints on the DNS server then manually populate settign for the two "OK" sites. With no DNS, clients will be unable to locate other sites.

I forgot to mention, there are no DNS settings on the server, everything is handled thru the router
usually in router have ip address default gateway.
remove the default gateway and add manually network route of 2 website
Remove the routers Default Route? hmmmm thats probably not the best idea now is it....

As for restricting access theres many ways to do this via host files via the browser or free software link below shows a few methods, but also try searching for URL blocking/filtering software something like K9 might do it.

Put those 2 sites in trusted zone in either IE or router and block all else
Suggestions in no particular order:
1) Use an old PC, add an extra NIC and install SQUID proxy on it (FREEWARE!).
    Now you can not only lock down access, but also report on it.
2) Roll out a GPO to lock IE to be able to access only those websites.
    You may also have to use a custom template for FF if you're using it.
3) Not recommended, but you can add the most common zones (.com, ,net, .org, .biz, etc etc) to your
    DNS server. That makes your server authoritative for those zones & will not query outside itself.
    Then put in entries for your two websites.
4) Depending on your router, you may have block / allow lists. Block all except for the two sites.
5) Employ 15 large trolls with studded clubs to stand and watch each user.
