Event Errors When Trying to Process Inbound AS2 Message RRS feed

  • General discussion

  • I am currently receiving the following errors in event log when trying to process inbound AS2 transmissions for a new BizTalk Server 2009 installation:

    The BizTalk HTTP receive adapter failed to initialize itself. Possible reasons:

    1) Receive location URL is not created/configured correctly.

    2) Receive location is not enabled.

    3) HTTP receive adapter is not running under a user that has access to management and message databases.

    4) Isolated host instance is not created for HTTP Receive adapter.


    The Messaging Engine failed to register the adapter for "HTTP" for the receive location "/hitachi/btshttpreceive.dll". Please verify that the receive location exists, and that the isolated adapter runs under an account that has access to the BizTalk databases.


    I believe I have correctly set-up everything and have reviewed many website posts regarding these errors to no avail.

    Any thoughts?

    Many thanks,

  • Hi,

    Confirm that the Identiy associated with your AppPool in IIS is in the BizTalk Administrators group.

  • What happens when you browse to: "/hitachi/btshttpreceive.dll"?  It should try to open the DLL unless you've turned off GET in IIS.  Most likely this is a permissions issue.  Did you create a BizTalk receive location with the uri: /hitachi/btshttpreceive.dll?  Did you also set up the handler for *.dll?


    If I recall that user also needs log on as service rights. 


    Kind Regards.
