[OpenLayers-Dev] ArcGIS + OpenLayers connection problem

Hi Charles,
I don't know if I've understood right but I'll try.

'basic' is the name of the "basic layer" as they've called at Metacarta 
in their WMS server.
I'm sure your WMS has a different set of names available for you.
to discover the list of names you can use a WMS client (udig, qgis, ecc) 
or just use your browser to access GetCapabilities of your server.
to do this use this URL:

http://server/arcgis/WMS?service=WMS&request=GetCapabilities

you should receive a XML file with a bunch of information and the list of server layers. User the value you find inside <Name> tag.

hope this helps
Ciao
