Flash IEClickToPlay ConfigMgr Compliance Setting (manipulate mms.cfg)

Recently we updated Flash to version 30.0.0.113 on Windows 7 systems and discovered that they are not able to view Skype Broadcast events in Internet Explorer as discussed in greater detail here on the Adobe Forum. We use them quite heavily at my firm and basically, the video never starts. You see the spinning wheel at startup of the Skype Broadcast. It only impacted IE whereas Chrome and FireFox worked fine. We obviously do not want to revert to an older version so chose to correct the issue.

Compliance setting to the rescue, however, I won't cover how to create one from scratch. We are using one to set this line below in mms.cfg so that Skype Broadcast will work in IE on Windows 7.

 EnableInsecureByteArrayShareableDomain=*.broadcast.skype.com  

The mms.cfg file is located in %WINDIR%\System32\Macromed\Flash or %WINDIR%\SysWOW64\Macromed\Flash depending on the arch. We have a Powershell Discovery Script that looks for this line in mms.cfg and reports back and then a Remediation Script that sets it if needed.

For the Configuration Item we set the Supported Platforms to Workstation OS' of Windows 7 and higher as it may impact Windows 10.

The Compliance Rules are pretty straightforward. We have two rules, one for System32 and the other for SysWOW64 locations. This screenshot is for System32 and it looks for the script to return 'OK' and if not to run the remediation script.

The remediation script will keep any existing lines and just modify the one in question as well as encode in ANSI so Flash processes it correctly.

The Compliance Baseline is deployed to our 'All Workstations' Collection to evaluate every 14 days. This will eventually get incorporated into our main Adobe Flash Compliance setting as it manipulates autoupdate etc. We actually just took our Flash autoupdate PS1 code and changed the top lines so its easy to manage multiple settings in mms.cfg via one Compliance Setting.

  $SettingsToRemove = @(   
  )   
  $SettingsToAdd = @(  
  "AutoUpdateDisable=1"  
  "SilentAutoUpdateEnable=0"   
  "EnableIEClickToPlay=1"   
  )   

On the client side, the baseline's compliance report is pretty straightforward.
