Cannot connect to wireless home network

Hi, I cannot seem to connect to my wireless network at home with my Vista Business Edition.
I have another Vista computer which I normally use that can connect and I am using the exact same settings as it.

I have noticed in the log files that I am getting the following notifications:

Communication denied by rule:
Blocked SSDP (UPNP) requests from svchost.

Not sure if this is what is blocking me from accessing the wireless network. CAn anyone help?

Thanks

Change the settings to allow sharing instead of strict protection, the setting is found on the Rules and Zones page under the personal firewall settings.
Be careful though, if your Business Edition is a work provided laptop altering settings might get you in trouble with your IT dept.
