Group_Cache_Refresh_cannot_obtain_a_connection_schedule_to_it_s_preferred_site_5_Rule (Rule)

Knowledge Base article:

Summary

No GC Logon uses the information in the replication schedule to determine when it should attempt to refresh the cache. Currently, there is no replication schedule defined for the preferred site; therefore, the cache routines cannot schedule an update.

Sample Event:

Preferred site: %1

Resolutions

Use Active Directory Sites and Services to check the site connectivity settings.
