I just noticed yesterday that my Windows XP Firewall is no longer enabled. It always has been so I don't know when, or how, it got disabled. When I go to Network Connections -- Properties -- Advanced, the Internet Connection Firewall is unchecked; when I try to check it, I get an error message as soon as I click OK:
"An error occurred while Internet Connection Sharing was being enabled. The dependancy service or group failed to start."
I tried using the Wizard, which set it to be enabled, but then it's not.
Does anyone know why this is happening and how to fix it?
