Can't install Active Directory Management Gateway Service on Windows Server 2003 DC because hotfix 969166 is missing

I need to install the Active Directory Management Gateway Service on two Windows Server 2003 domain controllers, in order to be able to use the Active Directory PowerShell module on other computers in the environment; this is required as a workaround to not having more recent DCs in the domain, which is a condition that can't be solved at the moment.

However, the aforementioned package requires hotfix KB969166, which seems to not be available anywhere, not even upon request (as it is instead the case for the other required hotfix, KB969429).

The download page states that "this hotfix will be eventually merged into the .NET Framework 4.0", but this doesn't appear to be a solution, because the 4.0 framework is actually installed on those domain controllers (as well as all available .NET updates), but I still get an error when installing ADMGS because that hotfix is missing.

I know we are out of support here; unfortunately, adding another DC to the environment is not an option. This notwithstanding, however, that package should still be usable, and the hotfixes it requires to be installed should be available.

How can I solve this?

Solution 1:

If you really want it:

http://hotfixv4.microsoft.com/.NET%20Framework%203.5%20-%20Windows%202000,%20Windows%20Server%202003,%20Windows%20XP,%20Windows%20Vista,%20Windows%20Server%202008%20(MSI)/sp1/DevDiv758402/30729.4174/free/392858_intl_x64_zip.exe

I wouldn't be surprised if you have problems with the installation or have to stand on one leg while reciting some medieval chant to get everything working.
