How to change default P2V port
VMM2008 will block P2V on source machines with an SSL cert registered on 443. To change the default port used by VMM, please follow these precise steps.
1. Go to Regedit->HKLM\Software\Microsoft\Microsoft System Center Virtual Machine Manager Server\Settings
2. Create a new DWORD reg entry named “P2VBITSTcpPort” and give it a decimal value of say 3043 or any other port that is not being used on the host machine.
3. Go to system services (services.msc) and restart Virtual Machine Manager service.
