Windows Server 2008

Time Server

Setting the primary domain controller to use an internet timeserver:

echo Setting timeserver
REM w32tm /config /manualpeerlist:ptbtime1.ptb.de /syncfromflags:manual /reliable:yes /update

w32tm /config /manualpeerlist:"ptbtime1.ptb.de ptbtime2.ptb.de ptbtime3.ptb.de de.pool.ntb.org" /syncfromflags:manual /reliable:yes
w32tm /config /update

net stop w32time
REM w32tm /unregister
REM w32tm /register
net start w32time

echo Send time to clients
w32tm /resync

w32tm /monitor

net time

If you have an environment with more than one machine, you can set a local server (e.g. the primary domain controller) as ntp server:

w32tm /config /manualpeerlist:"192.168.x.x ptbtime1.ptb.de ptbtime2.ptb.de ptbtime3.ptb.de de.pool.ntb.org" /syncfromflags:manual /reliable:yes
