I am having a similar issue (I think)
If I disable HTTP and RTSP on the server, and only have MMS enabled, then I
try to "test" a file in my publishing point (we are only doing On Demand), it
fails.
This is even on the local server.
I try all the IP addresses (2 NIC's and 127.0.0.1) and the computer UNC name
- all fails.
The Windows firewall is disabled, we have a nice Cisco PIX - and 1755 is
open for both UDP and TCP, no ports are being blocked outbound.
HTTP and RTSP work like a champ.
*stumped*
