Excahnge 2010 Server Failure and removal

Had a 2008 R2 server that was running Exchange 2010 and was a DC and GC server.  The raid array failed and was unrecoverable.  I migrated the customer off to a hosted exchange system and recovered all of the mail.  Now trying to cleanup the AD.  I have reinstalled Server 2008 and need to make this server a DC and remove the dead server from the AD for both the DC info and the Exchange info.  Think this might be a call to MS tech support...

If you had or have a failed DC in your environment, make sure that the FSMO roles are currently not on this failed DC. If they are "seize" the roles to another operating DC in first. What you will need to do is use the NTDSUtil tool and perform a metadata cleanup for the AD objects.

Metadata cleanup - http://technet.microsoft.com/en-us/library/cc816907(v=ws.10).aspx

You are also going to checked AD Sites and Services and remove any entries from there, that are left over from the failed DC. You can simply delete these objects if the DC has been removed from your environment.

You will also want to check the DNS _msdcs folder to ensure that all of your services records are pointing to the correct DC's in question. If you still see records pointing to the failed DC remove them.

As for the Exchange portion, it is important that you get your AD up to a clean operating state first. Once that is done, try to uninstall Exchange from "Programs and Features" from the Exchange Server in question. Simply remove Exchange, it will prompt for any pre-reqs before uninstalling. If you have issues uninstalling Exchange run the Setup.exe from the server and this should help with proceeding.

If this fails you might be left to remove Exchange using ADSIedit.

in a nutshell...

1) seize any fsmo roles if that server had any (hope you have other domain controllers available)

http://support.microsoft.com/kb/255504

2) use the above link to cleanup metadata
3) manually remove the exchange server using adsiedit

don't bother trying to uninstall exchange manually as suggested since you already stated the server is unrecoverable

Tried that first and get active directory object "server_name" cannot be deleted Access is denied.  I tried the command line tool and get a dsbind error...  I made sure that I am logically connected the the good DC.

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Make sure that you have the correct permissions to do this. "access is denied" clearly means you do not have the correct permissions. Make sure that you have Enterprise Admin and Domain admin rights as you will be seizing the Forest and Domain roles.

The account does have the correct permissions. I even logged onto a separate account that has the same permissions and received the same error.

What commands are you trying to run? Seize role command using ntdsutil? Also try running the command in an elevated command prompt.

I don't need to seize the roles..  They are still on the original server which is SBS2003.  The server that crashed was a server 2008 r2 with migrated Exchange 2010.  The sbs-server is still being utilized so I have not moved the fsmo roles off yet.  Just trying to delete the server 2008 DC out of AD.  I thought that maybe the system required a 2008 server in the AD due to elevation of the AD.  I wasn't sure if it was a good idea to DCPromo the new server while the old was no longer online...

If you are simply trying to remove a failed DC from your domain and you do not have access to this machine because it has phsyically failed or not turning on you need to use ADSIEdit and NtdsUtil to remove the objects from AD and cleanup the metadata.

This was stated in my first post. Also make sure that your account is part of the schema admins as well as parts of ADSIedit require this level of security.
