I just wanted to put this out there as it took days and days for this to get...um....discovered? I won't say resolved because we still cannot access our ArcGIS Server 10.1 services until the new SP rolls out. I'm hoping that this saves someone some time should they search for it. I"m baffled that there aren't more people with the same issue. Here is the response from ESRI.
This was found to be a bug with the web adaptor and the way ArcGIS Explorer initiates the request to add a server. ArcGIS Explorer sends the request using a slash, '/', after tokens in the URL. This is a known bug with the web adaptor, [#NIM082930 ArcGIS Web Adaptor (IIS) needs to handle redirect when tokens are accessed. ].
The request should still work with the slash regardless, and that is why the bug was logged. The web adaptor is fixed in version 10.1 service pack 1 allowing the request to be made with or without the slash so ArcGIS Explorer can add the server connection.
Thank you for contacting Esri support. This incident will now be closed.
Two steps forward, one step back....glad we were too busy to on-board a bunch of our staff with AGX before we found this error; so much for advocating for AGX as a business solution.
