LWE10124 : Howto monitor the time difference and synchronisation on all domain controllers at once

Symptom:

You need to control the time synchronisation

Cause:

This can be usefull if you find kerberos errors in your event log

Solution:

The time syncronisation is done by the PDC Emulator. This server should have a good time source for synchronising the clock. With the command

w32tm /monitor

SRV1.lubby.org [10.1.20.10]:
    ICMP: 0ms delay.
    NTP: +0.0000650s offset from SRV1.lubby.org
        RefID: SRV2.lubby.org [10.1.20.11]
SRV1.lubby.org *** PDC *** [10.1.20.11]:
    ICMP: 0ms delay.
    NTP: +0.0000000s offset from SRV2.lubby.org
        RefID: 'LOCL' [76.79.67.76]
SRV3.lubby.org [10.10.0.5]:
    ICMP: 20ms delay.
    NTP: -0.0139294s offset from SRV2.lubby.org
        RefID: SRV2.lubby.org[10.1.20.11]

you can check the time differences on the domain controllers. In the output you will find *** PDC *** which is the PDC emulator. This system has no timing difference because it is the time source.
