Windows Meeting Space

Apologies if this is the wrong group, feel free to suggest a more suitable
one but none of the groups seem to deal with meeting space.

I am trying to configure meeting space on Vista business on a 2003 domain so
that non-admins can run it. I have configured the firewall settings by group
policy and they show up in the firewall as enabled. I have also set the WMI
namespace security to allow authenticated user. With a non-admin account I
still get asked if I want to configure meeting space. The issues seems to be
with the local firewall rules that are available for meeting space, if I
enable them everything works but you need an admin account to enable the
firewall rules.

When I created the firewall settings gpo I only changed the ip address
settings to match our network rather than use the default settings. I
haven't tried SP1 yet.

Can anyone point me in the right direction?

Thanks
Andrew
