The path to the 'mapserv' application should be in fact a URL, which can
be accessed from any computer suitable for viewing the map. The path to
your map file is a file path within the server.
i.e.
layer = new
OpenLayers.Layer.MapServer("MyMap","http://myserver/cgi-bin/mapserv";, {map:
"c:\maps\mymap.map"} );
