Exchange 2010: Hub Transport Role Installation Fails

It has been reported by many people that Hub Transport Role installation fails while starting MSexchangeTransport service and below error reported in setup window when you try to install Exchange 2010 Beta.


The execution of: “$error.Clear(); if ($RoleStartTransportService) { start-SetupService -ServiceName MSExchangeTransport }”, generated the following error: “Service ‘MSExchangeTransport’ failed to reach  status ‘Running’ on this server.”


This usually happens when you disable IPv6 in Local Area Connection for some reason on Windows 2008 server.


  • Enable IPv6 in Local Area Connection.
  • To completely disable IPv6 on a Windows Server 2008-based computer, follow these steps and add a registry key:
  1. Open Registry Editor.
  2. Locate the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters
  3. In the details pane, click New, and then click DWORD (32-bit) Value.
  4. Type DisabledComponents, and then press ENTER.
  5. Double-click DisabledComponents, and then type 0xffffffff in Hexadecimal or 4294967295 in Decimal.

You can also use “Microsoft Fix It” available in KB952842 to disable IPv6.

Note: If setup still gives error, remove IPv6 entry from “hosts” file available at %systemroot%\system32\drivers\etc

    • Absolutely Vijay, that is what I am explaining here…

      This usually happens when you disable IPv6 in Local Area Connection for some reason on Windows 2008 server, which is not correct method.

      If you want to disable IPv6 then disable it through registry or keep it enable in Local Area Connection…

  5. Fresh install of 2008 R2 Core for my DC. Fresh 2008 R2 Full for my Exchange box. IPv6 is not disabled and is still bound via checkbox. Also hostfile in R2 has the ::1 line commented out already. – I get the abovementioned error

  6. Ran the install again and noticed the topology service wasnt running. i manually started it while the installer was wasting away and then all the sudden the install completed. I think this is what I had to do on the beta too…
