Re: Multicasting and the Multicast Announcement Wizard

I'm sure this has been covered elsewhere, but I'll go ahead and ask anyways... Is there anyway to decrypt an NSC file, and the manually encrypt one?

Well guys so far you've been very helpful in getting my servers set up and I really appreciate it, thanks. Now on to my question:

As a quick refresher, what I'm doing with my Windows Media Servers (WMS) is encoding a live speech, sending that encode to a central server that then Unicasts the stream to multiple WMS in different locations. Those WMS then multicast the live speech to the people in that location. What I've noticed is that Multicasting is pretty fickle about the format it streams in. If I run the Multicast Announcement Wizard and then make a small change to the way the stream is encoded then the Multicast servers won't stream anymore and I have to run the Multicast Announcement Wizard once again on each server. The problem I run into is that its our PR department that is going to be filming and encoding the live speeches and if they "accidentally" make a change to the encoder settings I don't want the stream to blow up. Is there any way to make it so Multicasting is more tolerant of stream changes?

Oh, in the Multicast Announcement Wizard I call the remote Unicast stream by: rtsp://servername/stream.

If I'm unclear what I'm asking please let me know and I'll try and clarify.

My conclusion: nsc files suck! I had lots of problems with them doing something similar. I don't know why Microsoft didn't just embed the nsc file information within the stream itself eliminating the need for them. I think they envisioned these files as some sort of access control which might also explain why portions of it are encrypted.

But to answer your question, I found no way to make the nsc files more "robust" so that they didn't break whenever you just looked at a setting the wrong way.
