More about Determining TMG Version Numbers
A common method for determining the version number for an instance of Forefront Threat Management Gateway (TMG) 2010 is to open the TMG management console and from the drop down menu select Help and About Forefront Threat Management Gateway…
Recently I discovered that this method may not be the most reliable way to determine the TMG version number. After installing Update 2 for TMG SP 1 (version number 7.0.9027.410) I noticed that the TMG management console was still reporting the build number from the previous update (7.0.9027.400 as shown above). However, using the script I demonstrated in a previous blog post the build number is reported correctly as 7.0.9027.410.
To verify the version number once more, I highlighted the System node in the navigation tree and clicked the Servers tab. Here the version number is again displayed correctly as 7.0.9027.410.
The moral of the story here is not to rely only on the Help | About Forefront Threat Management Gateway… drop down menu in the TMG management console to determine the version number. To accurately determine the TMG version, check the version number in the Servers tab of the System node in the TMG management console or use the COM script.
