The Messaging Engine failed to register the adapter for "WCF-BasicHttp" for the receive location "/OrderProcessingDescription/OrderProcessService.svc". Please verify that the receive location exists, and that the isolated adapter runs under an account that has access to the BizTalk databases.
The service account in Application pool identity is also a member of Biztalk isolated host users. I am still not able to get rid of this issue.
I am working on BizTalk Server 2010 and OS is Windows Server 2008
