I have my virtual copy of my AD structure just about all ready to go.
The DCs are on an isolated vSwitch on VMware ESX 4.1. The last step is
to set up time sync, I think.

According to
<http://www.sole.dk/post/how-to-configure-your-virtual-domain-controllers-and-avoid-simple-mistakes-with-resulting-big-problems/?p=387>,
it looks like I want to set the DC as "reliable", to act as it's own
time source (getting it from VMware Tools, which gets it from the ESX
server, which gets it via NTP from my production PDC DC). But that
article says "Configure virtual Domain Controllers, not to sync with the
time service by using the NoSync parameter and let the service know that
the server has an authorative time".

I am unclear on this "no sync" parameter.

MS says (<http://support.microsoft.com/kb/816042>), "Configuring the
Windows Time service to use an internal hardware clock
", to do:

To configure the PDC master without using an external time source,
change the announce flag on the PDC master. The PDC master is the server
that holds the forest root PDC master role for the domain. This
configuration forces the PDC master to announce itself as a reliable
time source and uses the built-in complementary metal oxide
semiconductor (CMOS) clock.

To configure the PDC master by using an internal hardware clock, follow
these steps:

Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags
In the right pane, right-click AnnounceFlags, and then click Modify.
In Edit DWORD Value, type A in the Value data box, and then click OK.
Quit Registry Editor.

At the command prompt, type the following command to restart the Windows
Time service, and then press ENTER:
net stop w32time && net start w32time

That's relatively clear. But where is the "no sync" that the first web
page spoke of?

So what changes (if any) should I make to the time service of this lab
AD, considering that it can't reach the outside world for an NTP source?
