Installing Vista Firewall without full reinstall

[ssubo]

I have installed Vista Home Premium without the firewall (using vlite) and now I can't share my folders because it says that a required service is missing. Is there any way to install Vista firewall without performing a full install or to install the required services for file and folder sharing?

Thanks a lot,

Ssubo
