just want to know if it is possible to set a non domain controller server to be an authoritive time server in a domain?

Here is what I have been asked to do:

set our 1st SUS server which connects directly to the internet to be the authoritive time server by setting it to synchronise with an external time source. Then point the Operations Master PDC Emulator to get its time from the SUS server.

Having read up on this I don't think this is possible because all the Microsoft articles I have read on it say that only a domain controller can be an authoritive time source on a domain.

They also say the Operations Master can only synchronise 1 of 2 ways, directly to an external time source or to an internal hardware clock. That would suggest you can't point it to another server on your domain and get the time from that?

However I don't know if thats Microsoft saying that because its their best practice so don't mention it can be done on a non domain controller or if in fact it physically can't be done.


I ran on the SUS server "net time setsntp server address" and then did "net time /querysntp" and it was pointing to what I had set it to. However I haven't yet tried setting the Operations Master PDC Emulator to point to that server. Anyone ever tried this?

Why am I doing this? Because we are decommisioning our Rugby clock server and we don't want any of our domain controllers having any connection to the internet.

TIA for any help

Thanks Kieran. We have a radio clock but we are getting rid of it and want to replace it with the NTP service. We don't allow DC's a connection to the internet, NTP is allowed through the firewall but only to the SUS server. Oh well back into work in the morning so will just point the DC at the SUS server if I can, turn off the server with the rugby clock, change the time on the DC and see if it corrects itself by sync'ing with the SUS server's NTP service.

Cheers. Got those printed off yesterday but didn't get round to trying them so will give that a go this morning
