After you add Host and Host-Instances to BizTalk, they are not useful and cannot be associated with Send/Receive ports until you relate the Host to the Adapter. This can be done in BizTalk Admin Console, but below is a program that allows you to do it with the BizTalk Powershell Extensions.

See related script to use Powershell to add new BizTalk Hosts and Host Instances.
