I have System Center Virtual Machine Manager 2008 R2 installed, and have a Hyper-V R2 host and a Virtual Server 2005 host. I'm trying to migrate my machines from the VS2005 host to the Hyper-V host, and keep getting the following error...

VMM is unable to complete the requested file transfer. The connection to the HTTP server myserver.mydomain.local could not be established. (Unknown error (0x80072efd))

Recommended Action Ensure that the HTTP service and/or the agent on the machine myserver.mydomain.local are installed and running and that a firewall is not blocking HTTPS traffic.

(Note - migrations between Hyper-V hosts managed by the VMM server work fine - my problem is just going from VS2005->Hyper-V hosts)

I have no firewalls turned on on either of the servers, and no firewalls in the middle. I've looked all over for answers to this problem, and am getting nowhere. All the articles I find when searching are talking about either V2V or P2V - and i'm just trying to do a straight migrate VM.

I've tried rebooting the boxes, changing the BITS SSL port number, restarting services, triple-checking firewalls, etc.

Does anyone have any good suggestions as to how I can resolve this problem?
