Exception: Unavailable Critical Extension. Server extended error: 8366. Server extended message: 000020AE: SvcErr: DSID-03210384, problem 5010 (UNAVAIL_EXTENSION), data 8610 . Adprep failed to verify whether schema master has completed a replication cycle after last reboot. [Status/Consequence] The schema is not upgraded. [User Action] Check the log file ADPrep.log in the C:\Windows\debug\adprep\logs\20160222090334-test directory for possible cause of failure.
