As you can see there are a lot of fixes in this rollup, I particularly worked in many issues involving 2501650 and 2502686 while the hotfixes were not even ready. Due the nature of those issues I strong recommend you to download this update and plan the installation on your Forefront TMG. To install this update, you must have TMG 2010 SP1 and Update 1 already installed.

  1. There is no such thing as Software Update 2 anymore. The name changed for Software Update 1 Rollup 1, 2 and now 3.

  2. Hello TMG User,

    No you don't. The only pre-req is to have Forefront TMG 2010 SP1 Update 1.

  3. KB says:

    If we have software update 2 installed, we can install this as well (it isn't explicitly stated above)?

  4. TMG User says:

    Do we have to install Rollup 1 and 2 before installing this rollup ?
