I'm running a TFS (2013) Server inside a Windows Server 2008 R2 Hyper-V VM (hosted on Windows 8). Everything seems to be running correctly within the server; however, when I try to connect to the Web URI of the TFS Server, I can't seem to see the server.

The VM is using a static IP and is able to see the network. I can access the VM from the network (i.e. if I type \servername\ into explorer it shows the VM exists)

What can I try / do to diagnose or fix this issue? Is there something specific that I need to do to TFS to cause it to be exposed to the network via a VM?

There server is accessible from within the VM.

Is the URL accessible on the VM itself? – TheCleaner Feb 12 '14 at 14:05
Yes, it is - question updated – pm_2 Feb 12 '14 at 14:23
Are you nesting VMs? – DanBig Feb 14 '14 at 14:20
What error do you receive? – MichelZ Feb 14 '14 at 14:29
No - not nesting VMs – pm_2 Feb 17 '14 at 12:47

Make sure you have disabled the Firewall. Also, disable Loopbackcheck on the TFS Server:

  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
  3. Right-click Lsa, point to New, and then click DWORD Value.
  4. Type DisableLoopbackCheck, and then press ENTER.
  5. Right-click DisableLoopbackCheck, and then click Modify.
  6. In the Value data box, type 1, and then click OK.
  7. Exit Registry Editor.
  8. Restart the computer.

and Disable StrictNameChecking:

  1. Click Start, click Run, type regedit, and then click OK.
  2. Locate and click the following key in the registry: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
  3. On the Edit menu, click Add Value, and then add the following registry DWORD value: DisableStrictNameChecking
  4. Right-click DisableStrictNameChecking, and then click Modify.
  5. In the Value data box, type 1, and then click OK.
  6. Exit Registry Editor.
  7. Restart the computer.

+1 for disabling the firewall. I had a similar issue with my TFS2012 server I had setup as a VMware server. Shutting off the firewall fixed it. Another thing to check, can you access the Web-side of TFS through your browser? – Lee Harrison Feb 14 '14 at 14:38
Yep - it was the firewall! Many thanks for your help! – pm_2 Feb 17 '14 at 14:04
