Some things to check:
Are you using DHCP? If so did you release the adress before shutting down the VM? (ipconfig /release)
Is there enough DHCP-adresses in the scope?
Is there enough ports in the virtual switch?
Does DNS work and do they use the same DNS? (This one is the most common one)
Does the account configured in the Quickprep-settings have enough rights to create and add machines to the domain?
