The specific operating system would sure help as well as the version of Internet Explorer, but assuming you're problem is the "Content Advisor Password", then....

The following steps will remove any password set in the Internet Explorer Content Advisor and allow you to reset the program to its original state.
1) Click on Start and choose Run.
2) Type in RegEdit and select OK.
3) Now click on the little plus sign to the left of H_KEY_LOCAL_MACHINE.
4) Continue to drill down, always clicking on the plus sign at the left of the named key, through Software, Microsoft, Windows, Current Version and Policies.
5) Now click on the Ratings folder.
6) In the right pane of the RegEdit window, you'll see an icon called Key. RIGHT click on it and choose Delete.
7) Next, choose Registry and then Exit to exit RegEdit. You've just deleted your original Content Advisor password.
Cool Restart the computer and run Internet Explorer again.
9) Click on ?Tools? in the upper left, choose ?Internet Options?
10) Click on the Content tab and click on Disable. When asked for a password, don't enter anything; just click on OK. This will disable Content Advisor because there's no longer a password.


Hope this helps.
