Adjust IIS Global Settings

You need to follow these steps only, when you're using Windows Server 2008 R2 or couldn't find the previous option "Start Mode" = "AlwaysRunning" in the Application Pool Advanced Settings.


In IIS Manager select the server  Global Settings  Configuration Editor


 Section  system.applicationHost/ApplicationPools – (Collection) Click on “…”


For MeetingManger and InvitationsManager Application Pool change the following property to:

  • StartMode = AlwaysRunning


After changing both Application Pools  save the setting on the right hand side  Actions  Apply.
