Hi TonyStone1234,
I would recommend you use Content Advisor to block specific websites
http://windows.microsoft.com/en-US/windows-vista/Using-Content-Advisor-to-help-block-inappropriate-web-content.
Here are the detailed steps:
1: Click the Start button, type INETCPL.CPL in the search box and press Enter.
2. Click the Content tab, click Enable..., click the
General tab, and then click Create password to create a password.
3. Then, click the Approved Sites tab, type the URL of the websites one by one and click
Never.
4. Click OK.
After that, those websites cannot be accessed until the Supervisor Password is entered.
Hope it helps.
Styx
