Now that Service Pack 2 (SP2) for Microsoft Forefront TMG 2010 is available I’ve had numerous people ask me about the process of slipstreaming the service pack with the Forefront TMG 2010 installation media. Having Forefront TMG 2010 with SP2 slipstreamed is a great time saver if you install TMG frequently like I do, but it is also essential if you wish to install Forefront TMG 2010 on a read-only domain controller (RODC). Last year when service pack 1 for Forefront TMG 2010 was released I wrote this post on how to slipstream the service pack. The process is nearly identical with Forefront TMG 2010 SP2 with the exception that there are a few more steps required because of TMG SP2’s dependencies on SP1 and software update 1 for TMG SP1.

To slipstream SP2 with the Forefront TMG 2010 installation media, begin by copying the contents of your Forefront TMG 2010 DVD or extracting the ISO to a temporary folder. Next, download Forefront TMG 2010 SP1, Forefront TMG 2010 SP1 software update 1, and Forefront TMG 2010 SP2. Software update 1 for Forefront TMG 2010 SP1 and SP2 for Forefront TMG 2010 are both .exe files that can’t be used for slipstreaming. To support slipstreaming we’ll need to extract the .msp files from them by opening an elevated command prompt and issuing the following commands:

For software update 1 for Forefront TMG 2010 SP1

TMG-KB2288910-amd64-ENU.exe /t d:\temp\SP1U1

For Forefront TMG 2010 SP2

TMG-KB2555840-amd64-ENU.exe /t d:\temp\SP2

Now begin the slipstreaming process by navigating to the \FPC folder of the TMG installation source and then issuing the following commands:

First, slipstream SP1 for Forefront TMG 2010

msiexec /a MS_FPC_Server.msi /p d:\temp\sp1\TMG-KB981324-AMD64-ENU.msp

Next, slipstream software update 1 for Forefront TMG 2010 SP1

msiexec /a MS_FPC_Server.msi /p d:\temp\sp1u1\TMG-KB2288910-amd64-ENU.msp

Finally, slipstream Forefront TMG 2010 SP2

msiexec /a MS_FPC_Server.msi /p d:\temp\sp2\TMG-KB2555840-amd64-ENU.msp

Once complete, use your favorite tool to burn a DVD or create an ISO file.

Important Note: If you install the Forefront TMG 2010 firewall client from the new SP2 slipstreamed installation source, you will still need to install the October 2011 Forefront TMG 2010 firewall client hotfix rollup as outlined in my previous blog post.
