I am trying to synchronize my deltaV sytem which contains about 15 SX controllers,10 operator systems,IAMS server,two Enginering workstations,one Historian.I did all the settings in Symmetricon S250 as per KBA NA-0600-0065.Now all my controllers and 6 operator stations are showing NTP server address as 10.4.128.1 (primary NTP server), but Proplus and two workstations showing NTP server None, and NTP protocol status BAD.So please suggest some workaround..
thanks in advance..
