Windows 2008 and 2003 AD problem

Hello,

My environment:

- 1 Windows Server 2008 SP2 DC, DNS, DHCP, holding  4 MSFO roles (all but infrastructure)
- 1 Windows Server 2003 SP2 DC DEFINITIVELY OFFLINE (holding only infrastructure role FSMO)

Problems:
I cannot transfer the Infrastructure FSMO role to the 2008 server (since the 2003 DC server is definitely offline)
1 want to do a clean delete of the 2003 DC from AD. It still appears in “sites and services” in AD DSA, in “domains and approbations”, ect….since it has never been demoted with DCPROMO

Of course I have AD replication errors in the event log, trying to replicate AD with the 2003 offline DC, I have also NTFRS errors, trying replications with the 2003 Offline DC, ect….

Questions:
- If I delete the 2003 Server from “sites and services” (in the 2008 DC) will it be enough to solve the FSMO missing role? If not how can I transfert this role to the 2008 DC ?
- Deleting the 2003 Server from “sites and services” will be enough to clean all AD from the 2003 DC?
- Any suggested procedure ?

Thank you

Use NTDSUTIL to delete the failed DC from AD - a full guide can be followed here:

Once it is gone - remove it from AD Sites and Services and then run DCDIAG and see how it is.

When you remove the failed DC via NTDSUTIL - it should seize the roles for you automatically.

If that doesn't work (which would be odd), then you can seize them yourself:

No, You need to seize the infrastructure role.

If not how can I transfert this role to the 2008 DC ?  
No, you can not as its offline, you need to seize it.

Deleting the 2003 Server from “sites and services” will not be enough, You will need to perform complete metadata cleanup steps along with deleting failed DC from AD sites, AD Users and computers and its DNS records.

@ alanhardisty: Yes, I know the EE rules, not any difference in my comments, I had no any intention to post duplicate comments my mistake but I was preparing for comments and at the same time you posted your comments.

So if I understood well
1) NTDSUTIL and it will delete the failed DC and should also seize the infrastructure role
2) If the infrastructure role has not been automatically seized, I do it manually
3) I delete the failed DC from AD sites

Right ?
Do I have to reboot the DC in all this procedure ?

Thanks

I know the feeling only too well :)  Please be careful in future though.  EE is fast-paced, especially so in the Exchange Zone and if you get distracted between opening the Question and posting - you may find a similar situation happening.
