There are TWO network adapters your VM can have.  Network Adpater and Legacy Network Adapter.

Windows should have the drivers for "Legacy Network Adapter" but "Legacy Network Adapter is provided by the Integration services.  They should be included in 2008 R2 but they will be NEWER with 2012, so you should install/reinstall them.
