Lync Server startup is pending.

Some configured critical applications have not yet registered. Applications: %1.
Resolution:
For script only applications ensure that the application is available in the path specified in the server applications list (you can retrieve the list using Get-CSServerApplication PowerShell cmdlet), and that no errors are reported by the Lync Server Script-Only Applications  Service. For non-script only critical applications ensure that they are configured to register on server startup.
