I have a WCF service on machine domain1\server1 that is accessible from a client on the machine domain2\clientA but not from machine domain2\clientB. From B I receive the error "the caller was not authenticated by the service (mscorlib, System.ServiceModel)".
The user account domain2\username is the same and this account has the same rights on the clients A and B; A and B are comparable machines.
The installation of the client software on A is via click-once deployment on Sharepoint succeeded on both clients A and B.
Has anybody an opinion on the cause of the difference?
What kind of configuration on domain1\server1 could be involved?
