SCVMM 2016,Error (2912) An internal error has occurred trying to contact an agent when creating new VM

To solve this problem you could change the BITS port SCVMM is using during transfers:

1. On your VMM Server open the Registry

2. Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft System Center Virtual Machine Manager Server\Settings

3. Locate BITSTcpPort which should have a value of decimal 443. Change this to some port unused in your environment. (e.g. 8800)

4. Restart Virtual Machine Manager Service so that the change takes effect.
