Hi,
We have written a SharePoint 2010 Service Application that is internally called by a custom SP WCF web service. The web service itself is accessed by a console application outside of SP. SharePoint is configured to use Windows authentication. The client is passing the credentials correctly. This solution is working for most SP installations.
In some situations we get the following SecurityException: Security error. The Zone of the assembly that failed was: MyComputer. The exception is thrown in the DemandAccess method of the Microsoft.SharePoint.Administration.SPIisWebServiceApplication class.
Does anybody know what this error mean?

Thank you in advance for your help.
