Windows server 2003 - Network Time issue

I am building this Windows Server 2003 environment which is just upgraded from Windows NT4 Server. I want to have PDC which actually is the upgraded server from NT4 and a BDC which is a fresh install of Windows Server 2003. After installing BDC and everything, I checked using dcdiag.

XXXXXXXXXXXXX is not advertising as a time server

The above is displayed in BDC's dcdiag result. So, I try to fix the issue by googling and get this solution finally.

net stop w32time
w32tm /config /manualpeerlist:peers /syncfromflags:DOMHIER /update
net start w32time
w32tm /resync
