environment: W2K FL, Mix of W2K and W2K3 DC's, One Forest, One Domain, 60
DC's, all DC's bar one
are relatively well connected (smallest link is 256k). One DC is
poorly connected on a very highly utilised 1MB
line :-(
Does anyone know
if there is a way to specify which DC a site uses when the DC assigned to that
site is offline? To be specific, I want to manage a situation where a site
is assigned a DC (or a bunch of them) and then those DC's fail. The
clients then will look up alternate DC's, but I want different subnets to lookup
different "secondary" DC's. So Site a has DCServerA, site B has DCServerB,
site C has DCServerC, Site D has DCServerD and site E has DCServer
E. When DCServer A fails, I want those clients to use DCServerE.
When one of DCServerB, DCServerC or DCServerD fail, I want them to use one of
DCServerB, DCServerC or DCServerD.
Sort of confusing
question to ask......anyone have any ideas? I know that DC dns records can be
weighted, but that is accross the board and would effect all sites right
?

Darren, looking into it now. I have been off ill for a bit and apologize
for "posting and running" so to speak. I will post my resolution up as
soon as I have it.

| You might consider placing a second DC in the site with
poor connectivity.
If all DCs are unavailable in a site, the clients will be
redirected to one of the DC that have registered domain specific SRV records. By
default, this means any any DC in the domain, in any site.
A common change made is to stop spoke site DCs from
registering these records and only allow the hub site DCs to do so. When all
spoke site DCs fail (in one site) clients are referred to a hub site DC and
never to a spoke site DC.
The KB offers further info, but I thought the above
"summary" was worthwhile :)
