CRM 2011 - “HTTP 500 - Internal Server Error” using SOAP Endpoint in Silverlight Webresources#
Requesting data over organization endpoint results in the following error.
HTTP 500 - Internal Server Error
The problem may be a missing provider-setting in the IIS configuration.
Solution:
Open IIS Manager
Select “Microsoft Dynamics CRM” Site
Doubleclick “Authentication”
Right click “Windows Authentication”
Select “Providers”
Add “Negotiate”
IIS-Reset
There should be two “Provider” entries.
Negotiate
NTLM
Cheers,
