  1. I applied above all the procedure in 2003 but my domain users still views all the websites which i don’t want. Please help me how can i allow only trusted websites which i added as per your instructions.

  2. How about if I’m not using IE browser because as of this time many preferred for Chrome or Firefox. I will be glad to know the answer.

    • Hi Grace,

      Sorry for the very long delayed replying to your concern. If there are a variety of Browsers used in your network I’d suggest using a Proxy server or Open DNS. If you have a hardware firewall like Sonicwall using the content filtering and/or Adding Rules to block certain sites, it will also suffice.

      Hope this helps.

      • please i need that fix very soon as i dont have any firewalls -only the domin and need to block some sites – hope to have answer from you with more explanation

      • You will need to reach out to your Network Admin, there might be some restrictions in your network that only he/she can change. There are other ways to have illegal sites blocked and again, only your Admin can deal with it.

  4. Hi…do you know any proxy server good for 100 users only. I want to use it in my domain just to deny/allow specific sites. I am a beginner in domain environment.

    • Hello, first off thank you for visiting my site. In regards to your concern, if you have a router and have access to its settings, it’s easier to block sites. Have you tried my tutorial on how to do this in GPO?

      • Dears,

        It works perfect! Your a life time saver. But I’m curious, what kind of router can block sites?It is a cisco router?
