Does anybody know what this error is?

[DanielDillard]

Screenshot is attached.  It popped up this morning when I navigated to our sharepoint development site.  The map had the Bing Aerial as base map and a feature service layer.  An extension was added with the ESRI Editor Widget enabled. 

I removed the Editor, the extension file, and the feature service layer and the error still appeared on refresh.  I removed the map web part and added it back and the error was gone.  It did not re-appear after adding the extension and the feature service back.

Hi Daniel,

I have seen this error mostly when service becomes unavailable. Reasons could be:
1. Cross domain file does not exist in the root of ArcGIS Server making service inaccessible.
2. Network issue ex: ArcGIS Server is not accessible.
etc.

Next time you get this error message please try to analyze the request and response using the Fiddler (http://www.fiddler2.com/fiddler2/) This will help to narrow down the issue.

I hope this helps.

Hello,

Can you tell me the exact location (relative to the install directory) where the root of ArcGIS Server is located, (ArcGIS Server for Java, using the built-in Tomcat servlet/server.)  I've tried placing the clientaccesspolicy.xml and crossdomain.xml files in several locations and was still unable to access the service from a different domain.

Thanks,
Chris

I have seen something similar but it is when I am getting a 401. Is the resource requiring the user to login?  What are you seeing with Fiddler? Are you using IE? FireFox?  Depending on the browser you will see varied results.
