Cannot access Intranet sites - blocked

I have the latest version 424 installed. I reset to all defaults, and am in automatic mode. I have a nework at 172.23.x.x and mask of 255.255.248.0.
It is in the trusted zones.

I seem ok accessing internet sites, using outlook, etc.... however, it will not resolve / connect to intranet servers.....all in the 172.23.x.x range.

The log is / was active, and it shows connections as blocked.

Can someone please help with this? Its making the firewall unusable.
