Solved: NetOp School NLSP.dll prevents streaming of Real Media via RTSP on student computers
- On a NetOp School system, Realplayer 14, when trying to load e.g. rtsp://dlib4.uncc.edu:554/e_reserves/CD4French1-7.rm (from Firefox, or disk, authenticated), crashes nlsp.dll (version 6, part of of NetOp School from Danware). This is the NetOp Browser Policy IP Filter.
- The MS-windows appcompat contains this:
