Windows Live OneCare: Firewall will not turn on

[guest]

I'm using One Care Live Beta 2.0 on XP Pro SP2 and I had to uninstall OC because I kept getting a warning saying that my firewall was not turned on. Here is what I tried to do:

•Turn it on - it gave me an error saying it couldn't turn it on and to try again later or restart.
•Stop and start the service. It would turn on for about a minute and then turn off again.
•Reboot. It would turn on for about a minute and then turn off again.
•Uninstall and reinstall. It would turn on for about a minute and then turn off again.
Like I said I finally uninstalled because it was not working properly. Anyone have any ideas?

In 1.x of OneCare, this would usually be indicative of a broken MSXML 4.0 installation, required for the firewall to function properly.



Searching Live Help for firewall in 2.0 returns this:

Some firewalls also prevent unauthorized programs on your computer from making connections outside.) service doesn't start correctly, you may be prompted to enable the firewall or you may find that you can't access or modify any firewall settings. You may also receive a message that states that the firewall service couldn't start.
