That's an awesome explanation, but I think there is still the bit about how
to tell what sysvol the client ended up using. Funny thing is, outside of a
trace, I don't see that as information that's accessible. At least not
easily.  

I'm still curious however.

Subject: RE: [ActiveDir] SYSVOL Question

Domain controllers generate SYSVOL and NETLOGON referrals each time a client
requests a referral. By default, the list of domain controllers listed in a
SYSVOL or NETLOGON referral are sorted as follows:

All domain controllers in the client's site are grouped in random order at
the top of the list. 
Domain controllers outside of the client's site are listed in random order. 
It is possible to configure DFS to sort the domain controllers outside of
the client's site in order of lowest cost. You can enable this feature by
adding the SiteCostedReferrals registry entry on each domain controller and
then restarting the DFS service on each domain controller. The DFS service
then obtains site cost information for all domain controllers and stores
this information in its site cost cache.

SiteCostedReferrals
Registry path
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dfs\Parameters\

Version   Domain controllers running Windows Server 2003.

When set to 0 (the default), SYSVOL and NETLOGON referrals contain domain
controllers in the client's site listed first in random order, followed by a
random list of domain controllers. When set to 1, SYSVOL and NETLOGON
referrals sort domain controllers in order of lowest cost. Domain
controllers in the client's site are at the top of the referral list,
followed by domain controllers sorted by lowest cost.

Subject: [ActiveDir] SYSVOL Question

I have a question...

When a user is authenticating to AD, what mechanism directs him to a
particular instance of SYSVOL?  And is there some way to actually see which
DC the client will be preferring?

I ask this because Microsoft has recently told me that in certain
circumstances, clients will always choose a different DC for SYSVOL than the
one they choose for authentication.  But I don't know how to actually see
that list so I'll know which ones are being preferred.

Thanks in advance,

Scott
