receiving: HTTP/1.1 304 Not Modified error trying to receive a stream

Having trouble accessing a streaming video file over a wan connection. This was working fine, but something seems to be giving me trouble. A packet trace shows me sending a request to the server:
GET /filename.asx HTTP/1.1

but then I receive an error in the reply
HTTP/1.1 304 Not Modified

and a request for
GET /filename.nsc HTTP/1.1

but then I receive an error in the reply
HTTP/1.1 304 Not Modified

Any idea what might be going on here. The workstations trying to connect are Win98 and XP
and the server streaming the info is Win2k sp2.
All machines local to the server's subnet can connect with out trouble. Their log shows:
GET /filename.asx HTTP/1.1
HTTP/1.1 200 OK

GET /filename.nsc HTTP/1.1
HTTP/1.1 200 OK

Any HTTP compression happening? Anyway:

304          Not Modified       The requested resource has not been
                                modified since the date specified in the
                                If-Modified_Since header.

304 - Not Modified. The client requests a document that is already in its cache and the document has not been modified since it was cached. The client uses the cached copy of the document, instead of downloading it from the server.

Hope this points you to your problem, after the link worked the first time, it cahed the file locally on the client, now it won't access it. Not sure on how to turn that cache feature off...

Any idea how to turn off or change http compression?

The cached file cannot be the problem, as it fails on workstations that have run Win Media player for the first time. I have this problem with everyworkstation the other side of my WAN, whereas it used to work.
