This may or may not help, but I thought I'd mention it:

There is a simple way to augment autosite coverage. You could set
regkeys to specifically assign certain DCs to cover the 'DC less' site.

The keys are type REG_MULTI_SZ and should go under
HKLM\System\CurrentControlSet\Services\Netlogon\Parameters.

SiteCoverage: This is a multivalued property that lists the sites the DC
will register for.  This is IN ADDITION to the site the DC is actually
in and the list of sites determined by autosite Coverage.

GCSiteCoverage: This is a multivalued property that lists the sites the
DC will register for in the role of a GC. This is IN ADDITION to the
site the DC is actually in.

Again, not sure if this helps or not, but thought you might be
curious...

Subject: [ActiveDir] AD Sites with no DC

I have a question regarding AD Sites and the best approach for physical
locations connected to the network, but which do not have their own DC.

Active Directory Sites can be created for locations that do not have
(and never will have) a DC.  An automatic process causes each DC to
advertise itself (through SRV records) in any Site that does not have a
DC and for which its Site has the lowest cost connections.  Through this
process, a client will automatically find the most appropriate DC.

The alternative to defining sites for each physical location would be to
configure the Sites covering the physical locations that have DCs to
include the subnets of the other physical locations that do not.  

Although it might involve more initial work, I prefer the first option
as it is more in-line with the concept of a Site being a collection of
subnets that have high-speed connections.  The second option potentially
includes subnets in Sites that are not well connected.

Any thoughts on which way to go?  Pros and cons?

Have a good weekend.

Tony
