Can't access my map service

DanielSchatt — Wed, 13 Apr 2011 12:38:14 GMT

hi, I'm trying to access a map service on our web server (which is a remote machine) and when I run my app from VS, I get a popup (Visual Studio Just-In-Time Debugger) that says there is an unhandled exception with the message:

"System.Security.SecurityException: A security exception occurred while trying to connect to the REST endpoint. Make sure you have a cross"

For some reason the rest of the sentence isn't visible but I assume it's talking about a crossdomain.xml file or a clientaccesspolicy.xml file. I do have both of those files in the root web directory of the web server (C:/inetpub/wwwroot). Does anyone know what the problem is? Thanks!

Do you have secured service from this remote server? If so, you need to use proxy page (Reference http://help.arcgis.com/en/webapi/silverlight/help/index.html#/Secure_services/016600000022000000/).What version of VS are you using? Change Framework from 4.0 to 3.5.

Good luck!

Suggestions:

Use Fiddler to see what is actually going on

Use FireFox and turn the Console on

Thank you for the tips! The problem appears to have resolved itself. I think the remote machine had to be rebooted and when I restarted a VS 2010 session without changing anything, it all worked and I didn't get the error anymore. I really don't know why..very mysterious, thanks again..
