Demoting old DC

 I have a  Secondary/Backup DC   (, Primary Died, computer crashed, it wont
 be turned on again) which  I promoted  to primary (didnt sieze schema 
master
 role)
 and then merged users and computer to a new dc with a different domain 
name,
 used ADMT and now all computers are on the new domain .
 I wont to get rid of the old DC by demoting it or  can i just remove the
 trust between the new and old domain and formatt the old DC?

 If not do i have to seize all of the FSMO roles before demoting it ?
 Any other tips what has to be done?

Hello polilop,

If you have all migrated to the new domain what you need to remove the trust. 
Now you can demote the source domain DCs.

As you have already created a new domain, you should have on that one all 
FSMOs available. The source domain FSMOs wan't be migrated to the new one. 
You can check with "netdom query fsmo" in a command prompt on the new domain, 
to be sure they are on the new DCs.

Best regards

DC Usage Advice
My applications painting is getting more complex and I've been thinking about drawing first to a memory DC before BitBlt'ing the bitmap to the screen in order to prevent flicker. However, speed is also very important for me and my testing showed that writing first to a memory DC was slower by over 400%.

But I'm worried about, not only the amount of memory my applica...
