Cause
It is possible for worker node system clocks to get out of sync with the Cluster Master if all systems are not getting their system clock times from an authoritative network time source.
Resolution
On all members of the cluster, including the Cluster Master, confirm the W32Time registry key is not set to "NoSync".
1. Use the Registry Editor and browse to HKLM\SYSTEM\CurrentControlSet\Services\W32time\Parameters.
2. Confirm the Type is not set to "NoSync"; it should either be set to "NTP" (a manually configured time source, set using the w32tm Windows command), or "Nt5DS" (synchronize with domain hierarchy).
Note: A server restart will be required in the event that this is changed.

Issue/Introduction
In a Distributed Architecture implementation, worker nodes repeatedly become disabled or otherwise inaccessible to case users with SystemClockValidator errors being logged in the server log file. Timezones are correctly set on all members of the cluster.
