Windows Time Service

Hi all

I cannot sync with an external time source so I have
changed my DC PDC emulator to not sync with an
external time source in the registry. After doing this my
clients still point to my other dc in the domain, any
ideas why? I have resarted the service. If I run a net
time command on my pdc emulator it also points to my
other dc? any ideas???

Many thanks in advance

Simon
