SCVMM 2008 Self Service
Recently I was asked what the flow of communication looks like when using the self-service portal to connect to a VM. Is the console traffic proxied through the SCVMM server or does the web-client connect directly to the respective Hyper-V server hosting the VM?
The answer is it depends!
If remote connections are enabled on the Hyper-V host, and allowed for the user role, and the CredSSP Security Support Provider is enabled, a connection is made to the Hyper-V host using port 2179 (or the port you specified when the host was added as a managed host). Otherwise, if all three conditions are not met, the Self-Service Portal will attempt a direct RDP connection to the specific virtual machine using port 3389. To allow the Self-Service Portal remote connection to port 3389, remote connections must be enabled and Integration Services must be installed on the target virtual machine.
