Just reinstalled Windows XP with SP3 slipstreamed via nLite. I use a router so normally have the firewall disabled. Needed to connect directly to the net for another reason and tried to enable the Windows Firewall. Went to control panel, clicked on firewall, was greeted with the normal message telling me it was not on and to change settings i would need to enable it. I told windows to make it so, and received an error saying it couldnt be done.
So, i went into services (services.msc), scrolled down to Windows Firewall/Internet Connection Sharing (ICS), right clicked it and chose start… received an “Error 5 Access is denied”… wtf?!?
Next i was off to google, came across a LENGTHY thread… http://forums.techguy.org/4034641-post37.html … that is the portion of the thread that finally solved it for me.
Basically i was somehow missing some registry keys…
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile]
“EnableFirewall”=dword:00000001
“DoNotAllowExceptions”=dword:00000000
“DisableNotifications”=dword:00000000
After entering those, i rebooted and all was well.
