How to Slipstream Service Pack 1 for TMG

June 29, 2010

Now that SP1 for Forefront Threat Management Gateway (TMG) 2010 is available, several people have asked if it is possible to slipstream this service pack into the installation bits. The answer is yes! For someone like me this is a tremendous time saver, as I typically install and configure TMG several times a week. Having SP1 integrated with the installation media ensures that I always have the latest version of TMG installed right from the start, eliminating the extra step of having to install the update each time I build a new system.

To slipstream TMG SP1, begin by copying the contents of the installation media to a folder on your hard drive. Next, open a command prompt and navigate to the \FPC folder, then execute the following command:

msiexec /a ms_fpc_server.msi /p <path_to_tmg_sp1>

For example…

msiexec /a ms_fpc_server.msi /p e:\tmg_sp1\tmg-kb981324-amd64-enu.msp

Complete the integration by following the prompts provided by the Microsoft Forefront TMG Service Pack 1 Installation Wizard (accept the defaults). Once complete you can burn the files to DVD or use your favorite utility to create an ISO image file.

    SP1 supports install TMG 2010 on domain controller, but i’ve done this splitstream procedure and got an error that says: This Forefront TMG setup scenario cannot be installed on a domain controller. Do you know how can i install TMG 2010 on a domain controller?

    Are you attempting to install TMG on a Read-Only Domain Controller (RODC)? The TMG SP1 documentation is pretty clear that only RODCs are supported.

    When installing TMG on a RODC, be sure that you are installing TMG with SP1 slipstreamed. You cannot install TMG on a RODC and then install SP1 after the fact. More information about slipstreaming SP1 with TMG can be found here: https://tmgblog.richardhicks.com/2010/06/29/how-to-slipstream-service-pack-1-for-tmg/.

    I’m sure I’m using a sp1 slipstreamed install, and that I’m running an RODC. However I’m getting the aforementioned error as well.. Has someone found a solution?

    Me too. I’ve slipstreamed SP1 but I still get this error on my RODC. Has anyone found a solution yet?
