Checking the VMWare settings (Edit > Virtual Network Editor...) I found that VMNet0 was indeed missing. Adding it proved a problem since it would not allow me to set it as Bridged (error that there were no non-bridged adapters available); in short, it was there, just not visible.
Did a bit of research and found some others had similar problems with Windows 8 to 8.1 - some recommended messing with the network adapter protocols (of which I do not recommend) but the best suggestion that worked overall was to simply re-load the installation media (or use the .exe if that's what you have) and run the VMWare Install Repair (you do not have to uninstall/reinstall). After the repair is complete, do a reboot of the server.
When the server has started up completely, open the VMWare console and check the network (Edit > Virtual Network Editor...) and VMNet0 (set as auto-bridged) should be displayed. Power up the VM and the network should appear as normal.
