You have a Windows Server 2012 R2 with the Remote Desktop Licensing role installed.

You restart your Windows Server 2012 R2 or restart the Remote Desktop Licensing Service.

In this scenario, the Remote Desktop Service may fail to start and event ID 623 similar to the below may be logged:

Source:        ESENT
Event ID:      623

Description:
svchost (PID) The version store for this instance (0) has reached its maximum size of 2Mb. It is likely that a long-running transaction is preventing cleanup of the version store and causing it to build up in size. Updates will be rejected until the long-running transaction has been completely committed or rolled back.

Cause

This issue may occur if there is a large internal table in the Remote Desktop Licensing Service (RDLS) database.
