Well that is exactly the problem. The OPTIONS request doesn't fail 
according to this snippit of the RTSP dialog. However it also doesn't 
return  a list of supported OPTIONS at all. Live555 library thus returns 
NULL although the Windows RTSP server says: "RTSP/1.0 200 OK"

-- snippit --

Sending request: OPTIONS rtsp:// RTSP/1.0
CSeq: 1
User-Agent: VLC media player (LIVE555 Streaming Media v2008.10.07)

Received OPTIONS response: RTSP/1.0 200 OK
Supported: com.microsoft.wm.srvppair, com.microsoft.wm.sswitch, 
com.microsoft.wm.eosmsg, com.microsoft.wm.fastcache, 
com.microsoft.wm.packetpairssrc, com.microsoft.wm.startupprofile
Date: Tue, 03 Feb 2009 17:14:06 GMT
CSeq: 1
Server: WMServer/

AFAIK live555 libraries doesn't have a way (or API call) to get the 
necessary information to resolve this.
