1. servers do have their own crdential, but it's not something you will have to worry about as an end user. When you access another server in the domain, you are using "your" credential instead of machine's credential
2. in the event that a machine's credential is being used, host's credential can't never be used by the VPC it hosts. Host and VPC are two totally seperate identities. From outside world, there is not differece between VPC and HOST.
3. If your vpc is not part of the domain yet, you need to join it into domain in order to use your credential to access domain resources as you would with HOST. Depending on your domain config, you might not have permission to join a machine into domain, however.
