Ace,
Thanks for your help.
I powered on the first DC which holds the PDC role first and the second DC
is off.
will the first DC look for the DNS server (another DC) in another site
(alive and across the WAN link)? The first DC hung on a while at "preparing
the network
connections'
Just wonder if I reboot one of DCs in production site, I do not have these
issues. it only happens when I shut down all DCs and power them on one after
another one.
Is it supposed to be? Should I turn off the WAN link between these two
sites and it will not query DNS server at the remote site?
Thank you!

In addition, DCs took a while at Preparing network connections when
powering
on.

Hi all,
Due to power outage, we have to shut down our production site
servers. When we power on our two domain controllers at production
site. It took a while to come up. Also, it took a while to log on.
When I check which server to log on, the logged on server is the
additional
domain controller at disaster recovery site (which is across the WAN
link.)
Currently, the two domain controller's DNS configuration is that primary
DNS is itself and second DNS is another domain controller at production
site.
What's the right procedures to power domain contollers up? How to
prevent
them authenticated to the disaster recovery site DC in case of powering
on?
(windows 2003 and SP2 environment)
Thank you!
Authenticating to a DC outside of a client's subnet all depends on your
Sites configuration. A DC coming up will query DNS, even if it is itself,
and a GC will be returned for the initial phase of the logon based on Site.
If all DCs are in the same Site, then Round Robin kicks in (DNS feature that
randomly picks one in the list of records).
There is no specific 'order' to power them up, however, I've always powered
up the Forest root DC first that holds the PDC Emulator. Your results will
vary. :-)
But it all depends on how you have your AD sites setup.
