VMM - VM status of Unsupported VM Configuration (Error 644)

I had provisioned a Standard W2K8R2 VM with the System Center Virtual Machine Manager (SCVMM) 2012.  Once installation is done, I attached the DPM ISO (with Share image file instead of copying it – tick in the box) to install through the VMM.  Everything went successfully, till I wanna detach the ISO.  I tried to detach the ISO but in vain through the VMM.

Error Message (Error 644) :

The specified host drive \\domain.local\Library\ISOs\SCDPM2012.iso does not exist on the host machine.

After some "bing”, it seems that it’s a common problem.  Steps carried our is as below :

• Launch the Hyper-V Manager in that particular server that is hosting the VM. 
• Detach the ISO or DVD, in the Settings for that particular VM and click Apply and then OK.
• Then go back to the VMM, refresh it and the error “Unsupported VM Configuration” is no longer there.

Hope the above steps helps.
