I apologize if this has been covered already. I'm working on a computer with WinXP Pro SP3 that cannot access "Internet Options" in IE7. It gives a message that the "operation has been cancelled due to restrictions in place" or something to that effect. Also, I can click on links on web pages, but I cannot type anything into a web page and then hit enter and have it do what it is supposed to do. For example, I can type a search string into Google and click 'Search' or just hit enter, and the computer just sits there and does nothing, but if I click on the Images or Maps link it will take me there. I just can't type anything into a form or a search box. I have been through the registry and cannot find anything that would cause this. There are no Group Policy settings in effect on this computer. There are no "NoBrowserOption" registry keys. I even imported a fresh, default copy of the Group Policies from another computer with a fresh install of XP Pro SP3, but nothing worked. I decided to uninstall IE7 and go back to IE6. When I did that I could access Internet Options but IE6 would not connect to the internet. Firefox, however, has no issues. I ran sfc /scannow but this did not fix anything. I'm wondering if I should just delete all the Service Packs and updates and reinstall them or if I should do a repair installation. Any thoughts would be most appreciated. Thanks in advance.
EDIT: I forgot to mention that I have run Malwarebytes and Combofix and neither one of these found anything. Spybot is not installed on this computer, nor is there any other program that could "lock" certain parts of IE down. Lastly, this still happens even with the firewall shut off. Hope this helps.
