deactivate nas
verified the nas probe version 4.73 is in the archive
created a backup copy of the nas probe folder
delete nas and alarm_enrichment in IM
delete the Nimsoft\probes\service\nas folder
empty the alarm_enrichment queue in the hub configuration gui

deactive nas probe again and move back the nas.cfg from the backup folder.
