Hi , When I try to run my browser based form and invoke web service to get the manager email ID . I get this error. The form works fine in the filler mode? An error occurred while trying to connect to a Web service. An entry has been added to the Windows event log of the server. Log ID:5566 Correlation ID:676e9a9d-03e4-7015-0e55-70b0110dc97e I tried using SSO and user explicit credential in the UDCX file locally located. But nothing seem to be working. Any suggestion I should do? Shruti

 I'm wondering based on the Log ID if loopback check needs to be disabled on the server (there are other workarounds too - disabling this is not the recommended approach, just the easy one).
