Q. How do I make the Directory Services Restore Mode (DSRM) administrator password work on my Windows 2008 domain controllers (DCs) if the Active Directory Directory Service (AD DS) is stopped and no other DCs are available?

0 (default): You can only use the DSRM administrator account if the DC is started in DSRM.

1: You can use the DSRM administrator account to log on if the local AD DS service is stopped.

2: You can always use the DSRM administrator account (This setting isn't recommended, because password policies don't apply to the DSRM administrator account).

Q. If I add a new writable Windows Server 2008 domain controller (DC) to a hub location, do I need to do anything to redistribute replication connections to my Read Only Domain Controllers (RODCs) in spoke/hub locations?

Q. I have a very slow link between a location and a hub. Can I increase compression on the replication traffic?

Q. Where should the primary DNS for a Read Only Domain Controller (RODC) that's a DNS server point?

If I have Exchange 2007 in only one location, do I need a hub transport server?
