Well found a thread on intel saying not to use their drivers but the ones directly from the manufacturer (Stone Computers) because there maybe compatibility issues
hum.. the problem only seems to be affecting the intel systems and only since last monday, I ve even installed the latest intel driver update
about 60 machines
Well use this script on your dcs:
net stop w32time
w32tm /config /manualpeerlist:"0.uk.pool.ntp.org 1.uk.pool.ntp.org 2.uk.pool.ntp.org 3.uk.pool.ntp.org" /syncfromflags:manual /reliable:yes /update
w32tm /config /reliable:yes
net start w32time
Also in dc group policy set servers to ntp
in other pc/ servers group policy put ntsds
