I have created a template on this system recently...but i just deployed a VM from a template and fully updated it with windows updates as of last week. And now when i try and create a new VM template from this VM and it fails with error 680....not sure what is causing the issue. i have disabled the Firewall on the Vm and still fails..
i am using VMM 2012 SP1 with UR4 and the VM is a 2008 R2 sp1 with all updates as of last week.
