I'm slowly learning the ins and outs of GeoServer, GeoExplorer, and other aspects of serving maps on a website. I assumed with this set up that I (or anyone else) would be able to access my GeoServer layers in ArcMap through WMS.
I installed the OpenGeoSuite Community Edition in the default directory. I have published layers with the proper settings and check boxes enabled. I can load the layers in a GeoExplorer map embedded in a web page (see: http://bit.ly/ecpGE2).
I have tried to load these layers into ArcMap using the following request (and many variations of it): http://donmeltz.dyndns.org/geoserver/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities& but I cannot get this to work.
A couple of hours of searching has not turned up a solution to my problem yet. I'm hoping someone on here can point me in the right direction, and provide me with some ideas of what to look at next.
