WCF-BasicHttp: Strange Behaviour

Hello,

I had a project up and running where BTS sent an XML to a WS via WCF. The whole thing ran on a VM. The server with the VM crashed and it was set up from a saved image on a new server again. I had to un- and reinstall BTS due to severe problems concerning the SQL DBs. Now that it’s running again I imported the project mentioned above. All settings are the same, yet when I try to send an XML I get the following NAck:

System.ServiceModel.Security.MessageSecurityException: The HTTP
request is unauthorized with client authentication scheme ‘Ntlm’. The
authentication header received from the server was ‘Negotiate,Kerberos,NTLM’.
—> System.Net.WebException: The remote server returned an error: (401)

I tried to create the physical port from scratch and even recreated the WCF-Binding in the orchestration, but to no avail.

I’ve seen the error before, but that was with SOAP stuff. I couldn’t really solve it. Has anyone a clue what’s happening now ?
