WMS not rendering in ArcMap

Discussion created by jfb_esri on Sep 12, 2013
Running ArcGIS Server .NET 10.0 sp 3 build Windows Server 2008 R2.  Customer indicates they can connect and add our WMS enabled ArcGIS server service with no errors, but no data is displayed in ArcMap.  A get capabilities returns valid xml.  The mxd the service is using contains UNC paths with the hostname.domain.xx.xxx The service's properties are also using hostname.domain.xx.xxx Some users can view the WMS.  So not sure if it's a site firewall issue or a configuration on our end.

Accessing the hostname/ArcGIS/rest'>http://hostname/ArcGIS/rest returns Error Invalid Code 404 - not sure if that is the cause or a differet issue.

I'm reluctant to run an ArcGIS Post Web install as this is on a production server.  I cannot provide a link to the WMS in this forum.

Thanks in advance for any help.
