I am seeing a strange problem where my Silverlight application is failing to load due to an "Load operation failed for query.." and the reason is "Denied Access at System.ServiceModel.DomainServices.Server.DomainService.ValidateMethodPermissions"
If I browse to exactly the same page using IE 9 the request goes through and the silverlight application loads! This is happening on more than one server and their IIS and SQL Server have been configured the same as all other systems we set up.
With custom errors turned off I see the following stacktrace in Fiddler -
Denied Access@Detail@DomainServiceFaultDomainServices i)http://www.w3.org/2001/XMLSchema-instance@ ErrorCode��@ErrorMessage�
Denied Access@IsDomainException�@
StackTrace�r at System.ServiceModel.DomainServices.Server.DomainService.ValidateMethodPermissions(DomainOperationEntry domainOperationEntry, Object entity)

at System.ServiceModel.DomainServices.Hosting.QueryOperationBehavior1.QueryOperationInvoker.InvokeCore(Object instance, Object[] inputs, Object[]& outputs)
The site is in my trusted sites.
When I attach to the silverlight application and debug the authentication process it seems to go through fine and the user is validated. But then when it actually tries to run the queries against the service subsequent to this they fail with access denied!
I'm lost as to why this would be any different in IE 10, any ideas would be appreciated! Thanks.
