Recently when I was deploying a new clean Skype for Business Edge Server, I ran into the following error: An error occurred while applying SQL script for the feature RtcDatabaseStore

To fix this download the SQL Server Management Studio from here:

Open up the SQL Server Management Console and connect to the server.

Navigate to Security > Logins

Now delete the following:

  • RTC Components Local Group
  • RTC Local Administrators
  • RTC Local Config Replicator
  • RTC Local Read-only Administrator
  • RTC Server Local Group

Now run Step 2 again:

Now it should work.
