Cannot Remote into Windows 8 Workstation on Hyper-V host.

I have a Windows 8 computer, hosted on a Windows 2012 Hyper-V server. I can connect to this workstation using the remote desktop application when I am on the Windows 2012 Hyper-V server which hosts the VM. But if I try to connect to the workstation from another workstation on the LAN, the connection fails. I can ping the Windows 8 VM from the lan and access the shared resources on the VM from the lan, but I just cant remote desktop in from the lan.

Any assistance would be appreciated.

Try connecting to the Workstation by IP address and not by name. There may be a NAT issue in the way.

With VMware, I would use bridged networking which normally gets around this issue.

can you RDP into it from Host Server instead of using Hyper-V.
What kind of virtual switch are you using ?

also, are integration services installed and up to date ?

John,

I should have mentioned that I attempted to use the ip address which failed. I can also ping the VM by using the computer name. So I believe that the name resolution is good.

Thanks

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

The vSwitch you have, is it the same one for host management or separate.

Did you try accessing by \domain\workstation ?  You may need the domain qualifier from outside.

Kash,

I can use the HYPERV manager from the host computer and connect to the Windows 8 VM ok. And if I am on the host computer I can RDP into the Windows 8 VM. Its just when I attempt to RDP into the Windows 8 VM from another workstation on the LAN does it fail. All components are up to date.

Thanks

John,

All the workstations are part of the same domain. Using the domain qualifier also fails.

Thank you

Are you sure Windows 8 is Windows 8 Pro and not Home

Also in Computer, Properties Advanced, Remote tab: Have you set for remote access. This might be an impediment.

In Network and Sharing Center, Advanced Sharing, are File and Print and Network Discovery both ON?  Make sure Homegroup is OFF (use "User names and passwords")
Stephen Weber - MCSE, CCNATechnical System Analyst / Enterprise AdministratorAuthor Commented:
John,

Yes, the Windows 8 is the pro version and part of a domain. Network discovery is on and I tested browsing the network, homegroup is off and file sharing is on. On the remote tab, I have allow remote connections and the box for network level authentication is off.

Thank you.

in the network settings of the VM is it connected to an EXTERNAL switch? Won't work if it is an internal or private switch
Kash2nd Line EngineerCommented:
I think its something to do with firewall.
Please try with firewall off on host and windows one by one.
if it works then you can add an exception to the firewall

@Kash didn't I say that 4 hours before you did?

It was a firewall issue, a different set of policies for the local vm switch. Thank you.
