Time Sync - 15 minutes offset

[Guest FB]

I have 180 PCs and i run a Script with NET TIME to check the time sync and

for my surprise there is 15 minutes difference (see distribution table below)

 

The Script runs in 3 minutes and i´m puzzled because AD is working fine but

there is a Default Domain Policy for block Logins when clocks are not

synchronized (5 minutes?!)

 

 

I´ve followed the article and my PC have a 3 minutes difference between my

PC clock and Atomic CLock

Hello FB,

 

The atomic clock is a internet time server or a hardware modul in your server?

If it is an internet time server use this way:

 

PDCEmulator:

 

w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes /update

 

With "peers" you can set the time source, either DNS name (time.windows.com)

or an ip address from a reliable time source.

 

Here you can find some of them:

http://www.pool.ntp.org/

 

 

Client configuration:

To configure a client computer for automatic domain time synchronization

 

w32tm /config /syncfromflags:domhier /update

 

After that run:

 

net stop w32time

 

net start w32time

 

Best regards

The Atomic Clock is provided by a .GOV.BR institution (tips on NTP.BR)

 

I´ll try your suggestion, but why the MS KB Article is not a good procedure?

Hello FB,

 

It is more complicated from my point of view to change all the registry keys.

It is not a bad solution, just another one.
