This is often the case if you use a public url for your Sharepoint of TFS server. To resolve this you need to add a registry key…

  1. Open regedit
  2. Open the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
  3. Create a new DWORD under Lsa named DisableLoopbackCheck
  4. Set its value to 1
  5. Restart the server for good measure

Its a FREE stand-alone Hyper-V server for Windows. Think of it as as Windows Server 2008 R2 with only the Hyper-V role installed. I’m a huge believe in virtualized server; whether they are on your own physical servers or up in the cloud somewhere. The ability to save states, create templates and change out your server(s) configuration on the fly is great. This product allows you to do all of that but with very low resource overhead. I already run Hyper-V on my servers so this will be an easy switch. Any new server I configure, this will be the base “OS”.
