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.
Jeff
Thanks – unlike all the blather across the internet, this actually worked. A pity MS can’t be as helpful as this.
Thank you John for letting others know that it worked for you. That makes the effort of putting this site together encouraging.
Jeff
Thanks for an easy fix. I was able to follow your directions and got my firewall back in a matter of minutes. Thanks again!
Thank you Lynnette for coming back to leave a comment. It will re-assure others that the fix works.
Jeff

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?
Jeff
Great info… it was the one (after severall others) that finally did it for me.

Do you think this fix will work on windows 7 as well?
Hi Suraj,

Jeff
Quality instructions Jeff worked a charm.
Hi Mike,
Thanks for your feedback. Appreciate it.
Jeff
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.

Could you please do a video of these steps ?
I’m following your steps but for some reason it still doesn’t work ???? I’ve done but the command sc delete SharedAccess is not working …
Hi Kan,
The steps is quite straight forward. As you can see from the comments, it has worked on quite a few Windows XP installations. I will however try and do a video, if can find the time, given that Windows XP will soon be retired by Microsoft.
Regards
Jeff
I have tried this i don’t know how many different ways. i am sure the problem isn’t your method, but rather a very cranky computer. i input the first prompt, and it tells me that installation failed. do i have any other options?
Hi Cali,
Have you tried re-applying your current level of service pack? or apply a service pack 3 if your current level is lower.
That may resolve your error.
Regards
Innocent

Thank you very much for your clear and IT WORKED instructions to restore Windows XP Firewall service!
Thanks RFH for the feedback.
Jeff
Thank you thank you thank you.
I have 2 computers in the same network, one with w7 and the other xp.
After downloading the trillionth last updates for xp until it run off of steam it seems that the updates had killed the firewall closing with it a bunch of ports that i needed for the comp to comp exchange. Closing Zonealarm was not helping.
So now firewall restored, problem solved.
((((((((((((hugs)))))))))))))))))))
Thanks Emi for the feedback. Great to know the solution worked for Firewall re-installation on Windows worked for you.
