To All experts in here,

I'm just wondering is it possible to configure my current PDCe to synch. with outside time source ?

I've been looking into http://support.microsoft.com/kb/816042/ as it is a registry hack it needs a server restart.

would that be possible to do it in other way ?
and also does that sync. can make all of the Desktop and other servers synched altogether ?

Please shed some light on this matter.

thanks.

You don't have to restart the server. You could use the following (command prompt) commands after you did the registry settings:

net stop w32time
net start

To sync the desktops with the PDC you could use the following two options (i would reccomend the fist one):

1.) Set the OPTION 042 in you DHCP server to point to your timeserver.
2.) Put the following line in the loginscript of all users: net time \\[computername] /set

I personally reccomend the user of the microsoft article you found. Otherwise you could use 3th party tools to synchronisze your server.
For example: http://www.timetools.co.uk/time-servers/ntp-client.htm

All members (running W2k or later) of an AD domain will sync their time by default. DCs will sync with the PDC emulator, members will sync with the authenticating DC. 
There is usually nothing to configure manually except letting the PDC emulator sync with an external time source, which are some simple commands in a command window:
net time /setsntp:1.2.3.4
net stop w32time & net start w32time

Replace 1.2.3.4 with the ntp server of your choice (from the list below, from your ISP, from wherever), and make sure UDP port 123 outbound is allowed. That's all.

Look over this link which has a registry key that you can import that will configure everything for you automatically.
