Windows 8 Connecting To Whs 2011 Homegroup

Has anyone tried this yet? I am running the Windows 8 RTM on a desktop and when I first set it up it connected to the homegroup and would see my WHS 2011 machine but hasn't been able to see it since I first installed Windows 8. It shows the server under home group in Explorer but when I click on it, it says The PC is currently unavailable. I can see it fine from Windows 7 machines, just not this 8 machine. I'm not sure how to troubleshoot a homegroup, any thoughts?

Thanks
