I have two Domain Controllers. We will call them DC01 and DC02.

I want to take DC01 down to replace a drive. We support numerous web apps and some of the web servers/sql servers are authenticating off of DC01 (provided by SET LOGON) and I want no interuptions (more specifically our GS customers want no interuptions).

What do I need to do to force the web/sql servers to authenticate off of DC02?
 
ad will allocate them a random available server from the site the machines are in, if dc01 goes offline at some point the members will realise and request a new dc, ad will then issue dc02 as the authentication server to use.

Just make sure the 2nd DC is a Global Catalog server and authitication should be fine unless the app has had a LDAP server spificied in the configuration.
 
Appreciate it guys.

I knew that it would fail over once offline, but I know there is a short period before it requests the new DC.

We have very strict customers.

Anyways, I just informed them that I was doing this and they will experience minimal downtime.

you should really get some raid5 on your dc... so if a drive fails you just throw in another
 
I sent out an interuption notice and replaced it within a single reboot.

Our DCs use raid 1. They do not need raid 5.

RAID 5 is actually slower that mirror for reads and he shouldn't have had to take down the server to replace the drive. Any server class machine would be hot-swap.

WE do raid 1 with an online hot spare. that way if a drive fails it auto rebuilds the array without down time. also you can lose 2 drives and function with raid 1 + online spare vs only 1 drive with raid 5.
