That is NOT the preferred way to remove a DC -- only how you must
do it if you have a failure of a DC when you have no choice. (i.e.,
"metadata cleanup".)

In generaly you should remove DCs by running DCPromo while they are
still working and online.

Make sure you have GCs and transfer the 5 FSMO roles (3 roles for a
child or domain which is not the root forest domain.)

Make sure you have DNS available. And WINS Server if you have
more than one subnet.

In a single domain forest EVERY DC should be a GC. Usually for
small domains every DC can best run DNS Server also (and maybe
WINS server if you have more than one subnet.)

Running DCPROMO on your machine will demote it gracefully and also transfer
the OM roles. You also have to think about DNS and WINS, etc. though. Have
a look at these:
