IIS 4.0 & ASX Playlists

Hey all. I've been messing around with ASX playlists, and have come across something that's not really important, but interesting to me nonetheless.

I have created an ASX file that works just fine, with nothing fancy in it, just ASX, Entry, Title and ref tags. When I open this file on my computer, using WMP 9, (as in open c:\pl.asx) it displays all the individual tracks that make up the playlist file, which is good.

However, if I put this file on a server running IIS 4.0, it does not display the individual tracks, and you have to skip through them in sequence to get where you want. Everything else about it works fine, minus the track listing.

My question is if anyone knows how to make the file when it's on the server display the individual tracks. Is this something it's supposed to do, is it a server config issue, an ASX issue, or a Media Player issue? Any ideas?
