Dead DC vs FSMO

Had a Hard drive fail on one of my DCs. In order to keep the network going I
had to shift DHCP and seize the PDC & RID roles to another machine.
Now the dead one has been rebuilt/restored (it was doing Terminal Licensing
and Certificate Services as well) and is ready to come back on line.
BUT, I am concerned that it will want to resume it's FSMO duties which the
Current AD has shifted else where. Also will I have a problem with DHCP?
Can some one maybe offer some guidance please?
How do I remove the roles on the restored machine so as to be inline with my
"current" AD structure? Or will it figure it out all by itself? ;-o
Thanks for your time...

The Ops Master role issue will resolve itself. The first time the restored
machine replicates with its neighbor it will learn that it no longer holds
those roles.

The DHCP issue is probably more of a worry. Particularly if your new DHCP
server is handing out the same IPs as the old server. You should boot it on
an isolated network first and disable the DHCP service, then connect it to
your production net and reboot and *verify* that AD replication has occurred
correctly.
 
Thanks Doug, I have booted the machine up with no Network connection to make
sure it was running OK.
But was not sure about letting it "talk" to the other DCs yet. I will
disable the DHCP for now, But I will want to put it back in service after I
dump the replacement.
I was more concerned about the Roles issue. Thanks again for the input.
