Hi,
This comes up now and again, just posting for my benefit and others.
When I have a small domain I like to configure the time-service to point to my ISPs DNS Server.
This means that my time source is external.
You have introduced your first 2008 R2 Domain Controller into your 2003 AD.
When you move the PDC role to your 2008 DC you are going to have to re-configure your time source.
Likely EventID12 with a source of Time-Service in your Domain Controller System Event Viewer Log.
To set this, open command prompt as administrator and type
w32tm /config /manualpeerlist:server,0x8, /syncfromflags:manual /update
Change the word server to your ISP DNS server address.
For example, if you were using Googles Public DNS Server you would type
w32tm /config /manualpeerlist:8.8.8.8,0x8, /syncfromflags:manual /update
Then Stop the Time Service
net stop w32time
Then Start the Time Service
net start w32time
To verify type
W32TM /resync
and then query the status
W32TM /query /status
This taken from

Nathan wrote a great article on this back in 2006 - it seems to have been taken offline, looks like it is much easier in 2008 |R2.

Just to clarify: not all DNS servers offer NTP. I didn't know that google did, but my ISP doesn't do it this way. |

I prefer using this list for time servers:

Yes, I don't know if Googles do either. I don't think ISPs want you to do this but the way I figure, if you are a small shop then it's one less thing to worry about.

On the SME front, there is a really nice post and all-round blog by Pierre Lemiuex

| I usually use pool.ntp.org (and then choose one of the pools local to where the servers are) |

Here's what I use, for those who want to use known time providers in the US. Run the following commands from an elevated command-prompt:
1. w32tm /config /syncfromflags:manual /manualpeerlist:"time-a.nist.gov nist1-chi.ustiming.org time-a.timefreq.bldrdoc.gov" /reliable:yes /update
2. w32tm /resync
3. w32tm /query /source (This should show the first external time source "time-a.nist.gov")

| I have a current Windows Server 2008 DC that syncs time with a local university's Naval time server (with permission). I have to retire this DC this summer and will be replacing it with a Windows Server 2008 R2 DC. What steps do I need to take to ensure this switchover is smooth and error-free? |

Once you introduce the new 2008 R2 DC, run my command as per the first post in this thread and substitute for your IP of the server you are using for controlling time.
Regards
EDIT: - Sorry - not sure if you mean time service or introduction of the new DC?
