When people connect to my organization's AGOL hosted services via a GIS Server connection in ArcMap (e.g. http://services1.arcgis.com/[Group ID #]/ArcGIS/rest/services , the 'Item Description' returns the error message 'The item's XML contains errors.'
BUT, the metadata/item details display fine when viewed via AGOL, ArcMap's Add Data AGOL search, and through the 'My Hosted Services' connection.
thanks in advance,
ps: Several of ESRI's services seem to have this same 'Item Description' problem (but some of theirs work) when accessed via a server connection in ArcMap:
