Exchange Rebuild Questions

I'll try not to get too long winded, but this one is complex.

We have 1 exchange 2010 box that is also a DC  (bad I know but thats how I got it). The AD database is damaged beyond repair per MS (however our primary dc with all the fsmo roles is fine). Only solution is to demote/promote, but I can't since exchange is installed. First thought was to create a new mail server, move everything kill old one. However I ran into issues, since AD was corrupt I couldn't attach to the new server, it gave me an authentication error regarding keybrose and AD issues.  So I'm ditching that idea, as it seems too risky now that moving these while AD is corrupt will probably do more harm than good.

So here is what I'm thinking. I am going to have to bite the downtime bullet, and just start exchange from scratch.  So if anyone can validate my steps please do and let me know.

1. dismount database and be sure they come down clean.
2. copy/backup/copy again the edb files
3. uninstall exchange
4. dcpromo box
5. disjoin from domain
6. use adsi edit to be sure it is all gone.
7. fire up new box
8. give it same name (to ensure less work on certs/dns/firewall etc.)
9. install exchange and rollups
10. create blank user mailboxes so new mail starts flowing right away
11. mount old edb's as recoverDB and start restores

Am I missing anything?

Do you think #8 is ok to do, or should I start with a new name just to be sure it is 100% clean and not using the old stuff. Obviously this requires a good deal of work since I then have to touch each user, but I have a feeling I'll be rebuilding outlook profiles anyway.

Will their group memberships all work? I'd assume so since it is tied to the AD user, but just concerned.

What is the most effective command to accomplish #10. Could I do it via csv, or some other script method?

One quick question. Do you have another Domain Controller? Or is this the only domain controller in the environment?

If a single domain controller. Have you tried starting up a new DC, replicating and moving all roles?

What are the errors you have in Active Directory?

What errors does DCDIAG provide?

What you are proposing seems to involve a lot of risk and I just want to make sure there isn't an easier way.

Yes we have a functioning DC that is defect free, but replication has failed because of the other one being corrupt.


Here is the output from repadmin

What to you mean AD corruption here? As you FSMO DC is fine, then how AD is corrupt on this DC. Also, If there is AD corruption, You can repair it. I don't recommend the steps you are looking to perform. As chances of Exchange failure is higher. In this case, I might just do a DC cleanup from ADSIEDIT. Also Share, how MS find AD is corrupt.

If it helps this is being generated in the event log since the break. I have not tried the steps suggested, will it hurt to do so?

The File Replication Service has detected that the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" is in JRNL_WRAP_ERROR. 
 
 Replica set name is    : "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" 
 Replica root path is   : "c:\windows\sysvol\domain" 
 Replica root volume is : "\\.\C:" 
 A Replica set hits JRNL_WRAP_ERROR when the record that it is trying to read from the NTFS USN journal is not found.  This can occur because of one of the following reasons. 
 
 [1] Volume "\\.\C:" has been formatted. 
 [2] The NTFS USN journal on volume "\\.\C:" has been deleted. 
 [3] The NTFS USN journal on volume "\\.\C:" has been truncated. Chkdsk can truncate the journal if it finds corrupt entries at the end of the journal. 
 [4] File Replication Service was not running on this computer for a long time. 
 [5] File Replication Service could not keep up with the rate of Disk IO activity on "\\.\C:". 
 Setting the "Enable Journal Wrap Automatic Restore" registry parameter to 1 will cause the following recovery steps to be taken to automatically recover from this error state. 
 [1] At the first poll, which will occur in 5 minutes, this computer will be deleted from the replica set. If you do not want to wait 5 minutes, then run "net stop ntfrs" followed by "net start ntfrs" to restart the File Replication Service. 
 [2] At the poll following the deletion this computer will be re-added to the replica set. The re-addition will trigger a full tree sync for the replica set. 
 
WARNING: During the recovery process data in the replica tree may be unavailable. You should reset the registry parameter described above to 0 to prevent automatic recovery from making the data unexpectedly unavailable if this error condition occurs again. 
 
To change this registry parameter, run regedit. 
 
Click on Start, Run and type regedit. 
 
Expand HKEY_LOCAL_MACHINE. 
Click down the key path: 
   "System\CurrentControlSet\Services\NtFrs\Parameters" 
Double click on the value name 
   "Enable Journal Wrap Automatic Restore" 
and update the value. 
 
If the value name is not present you may add it with the New->DWORD Value function under the Edit Menu item. Type the value name exactly as shown above.

Steps are same and I can see your dc is in journal wrap state, you can try these steps, 99% it should fix it.

I tried the steps on the event log for jurnwrap, but that didn't do anything either. Do I have any other options at this point? Only thing I haven't done is the authoritative restore. If I do that, what does this mean.

The FRS service must be disabled on all downstream partners (direct and transitive) for the reinitialized replica sets before you restart the FRS service when the authoritative restore has been configured to occur. How do I know who is a downstream partner (there shouldn't be any as there are only 2).

Also

The computer that is configured for the authoritative restore is configured to be authoritative for all the data that you want to replicate to replica set members. How can I tell if the primary working DC is where it will restore from?

Sounds like a plan, if you have a guide I can follow that would be ideal. If it helps this is the result of an integrity test. I've also tried a defrag, recovery and repair all via this article to no avail http://technet.microsoft.com/en-us/library/hh875546.aspx

Ok, first you can try to run dcpromo /force (http://technet.microsoft.com/en-us/library/cc731871(v=ws.10).aspx) and see if you are able to remove the DC.

Else try steps in below article
http://seneej.com/2013/06/30/clean-failedoffline-domain-controllers-from-active-directory/

Finally bring on more server and make it as additional DC. Don't install DC on Exchange.

And if  you feel you see any risk with above steps, last what is will do, is to setup new Exchange server and move all mailboxes to new Exchange server along with PF etc and then try above steps. Think and decide.

My concern is that I've read in more than one article that you cannot demote a DC while exchange is installed. You have to uninstall it first.

Therein lies the gist of my original post and the catch 22 I'm caught in.  I can't demote without breaking exchange, I can't install a new exchange server and move everything, because I've tried that but couldn't' connect to the server in EMC because of the corrupt AD issues (the old mailserver/dc couldn't auth the new mail server).

I've considered the below article, but it is basically what I'm suggesting and requires the downtime of an exchange restore.

This will be the final option, however it is complex and require downtime. If that is the way you feel comfortable to do it, go ahead and best of luck.
