i have a FAS 3140 with 2 controllers in active/active configuration.
Until today i had a Windows 2003 R2 DC where the 2 controllers log on.
This DC runs DNS service too
I have added some week ago a new DC W2008 R2, with DNS installed.
I have changed a week ago DNS on NetAPP to point to the new one.
Until now all seems OK.
Now in "NetApp OnCommand System manager" i see under "CIFS" then "Domain" that the old domain controller has status "connected" as \\%oldDC%.
I can see both the DC (2003 and 2008) as "Favored".
My question is: what happens if i turn off the old 2003 DC, as both controllers seem to be connected with it ?
Any impact i am not aware of?
Thaks in advance.

it's a basic ActiveDirectory thing: you don't just turn off the old DC, you have to demote it.
then it will remove it's records from AD/DNS. the filers will see this change in DNS and will only connect to the new DC, as no other DCs exist anymore.
