Halo PC and internet connection

[Red_5]

I'm running on a limited account on Vista, and Halo PC will not connect to the internet! I have allowed it through every firewall in existence and then some, and it still won't connect.

The funny thing is that Jedi Outcast and Jedi Academy, both labeled as "blocked " in the firewall config, connect just fine and dandy.

Descent 3 also does not connect. I have also noticed that Descent 3 and Halo use registry-based configuration storage, and both connect fine when I run as an administrator, which I can't do very often at all.

Can I give these programs administrative rights without a password or some other fix?

Thanks!
