I have a windows xp machine that I can't seem to enable windows xp firewall. This machine is not part of a domain and does not use AD.
The problem started when I installed a trail version of zone alarm and after the trail date was up I had to uninstall it. Now I can't enable the windows xp firewall. There must be some registry edits that the program does to disable the firewall. Does anyone know what registry keys are use to enable or disable the xp firewall?

Start?Run?type in ?services.msc? (without quotes)-- double click Internet Firewall/Internet Connection Sharing?if the service is stopped, click Start?then click Apply (if it is started, click Stop?Apply; then Start and Apply).

Although, if you just download Zonealarm (the free version) you will be far ahead of the protection that the MS firewall provides.

Type services.msc from the run dialog box, this will open a windows with a list of services available on your PC. In this list there will be a service called Windows Firewall/Internet Connection Sharing. The service has probably been disabled. Right click the service and select properties. Under the General tab of the window that appears there will be a field called start Startup Type. Select Automatic from the drop down list then click on the apply button. Now the start button under the service status field should no longer be greyed out, click the start button and this should enable windows xp firewall.

Can you explain your problem little more to help you better.

Meantime firewall service registry locations are

1. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\DomainProfile.

2. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center

You may want to tweak is the Windows Firewall component. If you have not included the firewall control panel (Start > Run > firewall.cpl > OK) , you can tweak these settings through the registry (Start > Run > regedit > OK).

Warning: Serious problems might occur if you modify the registry incorrectly by using Registry Editor (regedit or regedt32).

These settings all reside under the registry keys-

"HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\ Services\ SharedAccess\ Parameters\ FirewallPolicy\ DomainProfile"

"HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\ Services\ SharedAccess\ Parameters\ FirewallPolicy\ StandardProfile"

Here you can change the ports that are open or the applications that are added to the exception list, as well as the icmp settings. You can enable and disable the firewall through registry keys too.

Hi,

You could try the following command in XP.

netsh firewall set opmode mode=ENABLE profile=DOMAIN

Hope this helps.
