I'm trying to view my MGOS WMS service in ArcMap9.2 or uDig 1.18. Both
receive and process the capabilities info but neither draw the layer. I'm
able to manually request a map based on your helpful test tool which
generates
http://neomatix.linksysnet.com:8008/mapguide/mapagent/mapagent.fcgi?request=GetMap&service=WMS&layers=Tiger/Layers/places2&srs=EPSG:4326&bbox=-87.74,43.68,-87.69,43.815&width=500&height=500&format=image/png
but ArcMap just draws a blank and uDIG says RenderingConnection refused:
connect
Any hints on what else to look for?
