Stream Real player through isa 2006

I have a single nic set up, isa 2006 proxy that i can not stream real player via. I know it is not the firewall because if i avoid the proxy it works fine. A box comes up to use authentication but when i look at the log monitoring it still goes through as anonymous user. I can not allow anonymous out management requirement.

Here i a link for example that has real player streamed content that will not work

Please advise on how you have implemented the rule - what authentication have you placed on it?
In a single nic scenario where you cannot use Securenat approaches or the ISA firewall client, I personally find it is better to split each requirement into its own rule. You do not mention whehter ISA is a member of the domain or not?

The server is a member of the domain hence the authentication requirement. The rule is not just locked down to just rtsp. The authentiaction is to to active directory. i also added basic authentication so you get a prompt but it only works for initial authenication and then goes back as anonymous. I have installed the firewall client for testing and makes no difference.

here is  a link that may prove it is impossible?

ISA2000 was a different beastie in all aspects. I have been using realplayer for about 8 years without issue on all versions of ISA although I do not place authentication restrictions on the use of realPlayer. I just accepted that this was one area that had to be added through a no-authentication rule which gets run before the normal AD-controlled allow rules. I then use the ISA built-in reports to review use through the reported ip addresses rather than the username.

As for the first point, i wasn't sure if you were checking authentication locally, via domain access or through ldap lookups.
