Let's start off by saying that I have never done this but I wanted to publish (if thats the right word) the Firewall client to all the client computers. I configured Automatic Discovery without any problems. Tested it and it's working perfectly. I found microsoft KB 838122 and did exactly as it says to deploy it via group policy. Problem is, as soon as I enforced that GPO and a user restarted her machine it kept asking her for her windows credentials. All of the clients are local admins and this shouldn't be a problem but I couldn't imagine why this would happen? Am I missing something here? I made a dedicated GPO which doesn't contain any other settings so I doubt that it could be the GPO. Btw, my client is running SBS premium.
