Internet Explorer Blocked by ZoneAlarm
My primary browser is Mozilla Firefox. Although I access the Web everyday, I hadn't used Internet Explorer (IE) for at least a week.
Everything except Internet Explorer can access the Internet without a problem.
- Mozilla Firefox
- Mozilla Thunderbird
When I try to access any Web site with IE, I can see that the domain name usually resolves to an IP address in the status bar on the bottom, but IE never displays the Web page, and usually times out.
- OS: Windows XP Professional SP2
- Internet Explorer 7 (v7.0.5730.11)
- ZoneAlarm v7.0.337.000
The last updates to IE, as listed in Windows Update, are:
Cumulative Security Update for Internet Explorer 7 for Windows XP (KB944533)
Friday, February 15, 2008
Cumulative Security Update for Internet Explorer 7 for Windows XP (KB942615)
Wednesday, December 12, 2007
- Rebooting the computer did not correct the problem
- Logging in under a different user/profile did not resolve the issue
- IE works after shutting down ZoneAlarm
- Mozilla Firefox has no problem accessing Web pages, so this issue was definitely isolated to Internet Explorer
- Resetting Internet Explorer settings did hot correct the problem: Tools > Internet Options > Advanced tab > Reset button.
- Deleting Internet Explorer from ZoneAlarm's Program Control and letting ZoneAlarm use Auto settings did not correct the problem. (Access: Trusted: Allow and Internet: Allow / Server: Trusted: Ask or Block and Internet: Ask)
- Upgrading ZoneAlarm from v7.0.337.000 to v7.0.462.000 did not correct the problem
- Possible incorrect configuration of IE's access rights in ZoneAlarm after an update to IE. Check windows update history to see when IE was last updated. Does IE's update coincide with the access issue?
- Possible corruption in ZoneAlarm's configuration database.
Fix / Resolution
The following worked:
Reboot Windows into Normal Mode
After rebooting into normal mode, set the new network found as Trusted.
- Reboot Windows into Safe Mode
- Login as a member of the Administrators group
- Delete the following ZoneAlarm files from C:\WINDOWS\Internet Logs\
