Any issues if i remove a DC from the lan?

hi all

we have 2 server 2008 domain controllers - DC_A and DC_B

i urgently need DC_B some where else - i plan on doing a bare metal restore to it from another production server! extreme i know but seriously i have no choice..

what i want to know is, am i blindly ignoring something if i remove this server from the lan?

(DC_A has all 5 fsmo roles assigned to it)

and do i need to tell dc_A that dc_b no longer exists when i do remove?

As long as you have verified all FSMO roles reside on DC_A and all clients are looking to DC_A for DNS you should be okay. Are both DC_A and DC_B GC's? Make sure you have a GC or else you will have some fun logon issues. Aside from this the process is simple.

Run DCPROMO on DC_B and remove AD Components, reboot once complete.

Disjoin DC_B from AD once AD has been removed.

Verify domain functionality... make sure users can resolve server names, logon, access shares etc.
As long as you run dcpromo to remove the DC from your domain first you shouldn't have any problems.
Make sure that if you are also using DC_B for client DNS that you update DHCP settings for you clients so they aren't attempting to do DNS lookups on DC_B.  Otherwise should be totally fine.

i created DC_A , as the first dc on the lan - then i created dc_b and joined the domain - but i never transfered any fsmo roles to DC_B - so that should be fine?

yea both are Gc's

Why do you need to do a restore, at your new location just stand up the new box and run dcpromo to promote and let AD replicate.
Also after demotion you have to manually delete the DC_B server object from sites and services. (won't happen automatically)

mike--its not a dc i am restoring to it but an sql production server
No matter what do you want to do with DC_B later.
If you do not plan to use it as domain controller in the future - you must remove  Active Directory from it first. After that, you will have a member server called DC_B in your domain. What do you want to do with it - is up to you, it has nothing more to do with AD.
