Work out your name resolution problem.. Since you say your running in workgroup mode, doubt your running local dns. Guessing your router is your dhcp server? Some routers take their dhcp clients and make them resolvable via dns - many do not?
So that would be one option, or you could run your own - you do have a 2k8 server sitting there at your disposal that you could turn on both dns and dhcp that support dynamic dns registration via dhcp, etc.
Or you could even run wins server on your 2k8 box if you want netbios name resolution. Or yes last resort in netbios name resolution is broadcast, are you boxes all on the same network segment - or do you have your VMs different network than your host? How many network cards do you have your hyper-v box and how are they setup to your physical network.
For all I know your trying to run 2 different network spaces over the same physical wire? Which is why your broadcasting for names is not working? Or you have your node type setup for p-node which only asks wins and never broadcasts and your not running wins, etc.
Going to need a bit more info on how your setup if you want real help in troubleshooting your name resolution problem.
You could always resort to using host or lmhost file on your boxes to resolve your host and netbios host names.
Lets forget the RD web thing for a bit, from a command line on try and ping your different clients host names, and from a couple different boxes try doing this for your different names. If they come back with IP when you ping them

Now the first time was via dns and it was very fast in resolution - then I turned off my local dns, and flushed the local cache and then pinged int by name again - and it took a few seconds to resolve, since it was via broadcast but then you can see it does not return the FQDN of the host, only the netbios/host name.
Have to look into this RD web thing - maybe for it to work it has to use dns, which would make sense vs it doing broadcasts. Which you have 2k8 server there it would take a few minutes to setup dns you don't have to run AD to use dns, but you do have to use dns if you want to run AD
