Is there a way that I can block specific site URLs with a pass word?

Answer 1

Unfortunately, no. If you are using Internet Explorer, you can use the Content Advisor option. However, it does not block specific websites, just websites with certain objectionable content (e.g. pornography, gambling...etc.) You can block specific websites by editing the hosts file. It is not easy do but I can walk you through the steps if you are interested. Just send me an e-mail.

Answer 2

Yes there is a program called netdogadmin that you can find at download.com.

Or

You can use the IE features. Go to tools - Internet options - Security and click on the blocked sites button.
