In order to build a test platform to migrate an Exchange Organisation from 5.5 and 2K to 2K3, I installed a test platform.
Firts, I installed a W2K (SP4) server as the server of the root domain test.com.
Then, I installed a child domain (W2K3) a.test.com.
Before installing the child domain, I launched the forestprep and domainprep of W2K3 CD on the controler of the root domain.
Wen I restart the W2K server, following messages are logged in the System EV:
Type : Error
Source : W32time
Event : 62
This machine is a PDC of the domain at the root of the forest. Configure to sync from externam time source using the net command 'net time ...'
This message is logged several times (2 per hour).
There are also 2 warnings : 5781 and 54.
On the child domain (W2K3) I can find following warnings just after having rebooted : 40960 and 40961. According to the article 823712 of Microsoft KB, it is not necessary a problem).
The W2K server is the time server for the W2K3 server (KB 216734 and 257187)
I wan't to be sure that there isn't any issue on this side before doing Exchange tests.
