An update to Lync 2013 Active Directory Policy Tool

Based on some feedback, we updated this script (Originally posted here) to version 2.4.2.

This version added some fail-safe warnings and some errors were resolved.
The biggest change however is the ability to default groups to the Global policy or Dial Plan.

Lync Server Installation Error: Prerequisite installation failed: Wmf2008R2

Trying to Install Lync 2010 on Server 2008 R2 SP1, the installation failed with the following error while adding the first Lync Server Components:

Update: I Initially published this post in March, when I first encountered this issue.
My workaround was to rename the files names as you can see below if you read further.

The official workaround for this issue has been released in Microsoft KB2522454. To sum it up, you should run the following command before installing Lync and reboot:

%systemroot%\system32\dism.exe /online /add-package /packagepath:%windir%\servicing\Packages\Microsoft-Windows-Media-Format-Package~31bf3856ad364e35~amd64~~6.1.7601.17514.mum /ignorecheck

It appears as if that file:
Cannot be found.
I looked for that file. It’s no where to be found. But it looks like it has a different version:

I copied the file name mentioned in the error message, changed both file names (both .cat and .mum, didn’t know if they need each other during installation) and tried installing again.

That Solved the problem:

I changed back the file names to their original names and restated the server – everything works fine.
Perhaps a Lync Server 2010 RU1 soon?
