Jeff,

Want to let you know that your ‘How to Remove and Reinstall Windows XP Firewall’ procedure worked perfectly. It was explicit enough to accomplish the task. Many other websites I tried weren’t detailed enough for me to successfully remove and reinstall my Windows Firewall in Windows XP Pro.

I still have an issue you might be able to help me with.
My Window Security Center displays correctly on for a short period of time after it is started manually using the WSC properties dialog. It’s status is normally Stopped when it should be Started. If I start it, it runs for a little while and then stops. Something is causing it to stop. I first suspected that Windows Firewall was corrupt. Since the ‘un/reinstall’ process didn’t resolve my problem, I need to find what it is that’s closing the ‘Security Essentials’ panel of the Security Center. The Security Essentials panel shows the On/Off status of the Firewall, Automatic Updates, and Virus Protection. I uninstalled third party anti-malware (protection) software and the problem persists. I can’t remember when I was last able to control Windows Firewall and have it respond correctly to settings made in the ‘Manage Security Settings For:’ panel of the Security Center. Settings control for Internet Options and Automatic Updates function normally.

I’ve been fighting this problem for a long time and thought maybe you might have a solution or could make some suggestions since your ‘FixItDesk’ tech tip was able to help me rule out that Windows Firewall is not the root cause of my problem.

Thanks for any help you may be able to provide.

Hi Bernard,

I would suggest re-installing the version of Windows Service Pack on your system.

I have successfully deleted windows firewall but after I enter the command to reinstall it I receive this message: ERROR IN SETUPAPI.missing entry installhinfsection . What does this mean? My. Bigger problem is DNS server issue which I suspect is due to windows firewall being deleted when I downloaded 3 rd party security

Hi Stacy,

The error could be caused by a number of things – a corrupt Windows/Registry file, or malware/virus infection. Have you tried repairing Windows installation, that is if you have your installation CD?

Many Thanks Jeff

We were not able to ping computers on the network despite the fact that users were logging on and working normally.

Our remote capability was hampered and any support had to be provided by visiting the user personally.

We did notice that Windows Firewall service was automatic but not started, and when we tried starting it – it threw an error

After following the process mentioned by you we could get this thing going.
