I've been playing with this forever, it seems, constantly changing things - I think this is how it's setup currently:
The only Site and Content rule enabled allows everything for the Internet group.
2 protocol rules enabled:
Internet Access allows FTP download, Gopher, HTTP, HTTPS
RealPlayer allows PNA (self made) port 1090 TCP Outbound, PNM Client, PNM Server, RTSP Server
HTTP Redirector is set to redirect to local Web Proxy, but I've had it set to send to requested Web Server in the past and same issues have occured.
Using RealOne client with a user in the Internet group - have tried both configurations - 1) no proxies configured in preferences and 2) proxies configured for all 3 protocols (using netbios name and IP address)
All of the content displays correctly, except when I click on a media link . Then I get errors about Connection to proxy server, Connection to server, or General Error has occured, depending on what I have configured in the preferences for proxy settings.
My ISA logs show mostly authenticated entries that succeed using the Default Allow Rule and my Internet Access Rule. The Real Player protocol rule is never touched.
Where it fails is when there are anonymous entries. They get HTTP Error Code 407 - proxy authentication required.

Anyone know why there are these anonymous entries stuck in sporadically with my authenticated ones?
