Hi

I am shortly going to remove the first domain controller in the domain (we just have a single domain setup)

I have transfered all of the FSMO roles and made the replacement DC a GC and installed DNS, the next thing i need to do is change the NTP time server on the new DC i run the command below
net time /setsntp:ntp2a.mcc.ac.uk
i have stopped and restarted the w32time service

if i type net time from the command line of the new DC it still shows as reciving time frm my old DC

Is there somthing i have forgotten.

Thanks

Nick

You need to set up the new DC as a time server for the domain.  Here's a link to an article on how to do this:

You only need to transfer the PDC emulator role (and configure the time server like you already did), nothing more.
Every DC in an AD domain will autmotically sync with the PDC emulator, and every member will sync with the DC authenticating it.
You can *NOT* use "net time" to determine the time server a machine uses. "net time" knows *nothing* about AD time hierarchy, it just queries the browser list for a DC.
"net time" can be used to configure the time server on the PDC emulator, but that's about all it's good for in an AD domain.

I have to disagree with oBdA - the net time command can be used to set and query the sntp settings of the local time server.  However, even if you've transferred the PDC Emulator role, as it appears you probably already have, you can run into problems if the new PDC Emulator is not set up properly as an authoritative time server for the domain.  If you follow the steps in the article I cited, you will ensure that everything is set up properly and that all other clients and servers in the domain will see this server as the authoritative time server for the internal network.

Use NTDSUTIL to transfer the PDC emulator role. http://support.microsoft.com/kb/255504

IMPORTANT: Transfer, don't seize
