When launching Exchange Server 2010 setup you may encounter this error message.
The Exchange Server is in an inconsistent state. Only disaster recovery mode is available. Please use Setup /m:RecoverServer to recover this Exchange server.
This can occur when the Exchange server object already exists within Active Directory, which can occur when a server has been uninstalled and you are attempting to reinstall it.
If you do not wish to use disaster recovery mode to reinstall the server you must first remove the Exchange server object from Active Directory.
Launch ADSIEdit.msc and navigate to CN=Configuration, CN=Services, CN=Microsoft Exchange, CN=<Your Organization Name>, CN=Administrative Groups, CN= <Exchange 2010 Administrative Group>, CN=Servers, CN=<Server Name>, and then delete the server object.
In this example screenshot the server name is EX2.
After deleting the object you may need to wait for the change to replicate throughout Active Directory. Then you can relaunch Exchange setup and proceed with your installation as planned.
About Paul Cunningham
I had to open the advanced settings on the Connect To and change to Global Catalog inorder to see the Object. Now that i have found it, I am unable to delete the object though. I am logged in as Domain Admin account, tried on workstation, and both DC. i see the Delete button (red x) but it wont let me remove anything. click it and it does nothing!
any ideas?
Tim, I’ve never encountered that problem before. I guess make sure you’re running ADSIEdit.msc with elevated privileges.
I don’t usually use the red X either, just the Delete key on my keyboard.
Great work its what I neded.
Thanks Bro Best Regards From México City
Thanks a lot. I had to go to the Advanced Settings and Select a well-known naming context (option Configuration). I also had to specify the Administrator credentials for the DC.
Very big THANKS. It helped me
You’ve saved mse a heap of work – great article.
Thanks again.
All the the best from Belfast…
Hi,
We had a crash on a Exchange server and had to reinstall the server. We had to rename the server before we managed to install it. So now I can see both server in the EMC. It is just to delite that old object with ADSI edit and then it would be delited from EMC too or do I have to do more, like a metadata cleanup?
So a recovery install wouldn’t work?
I wouldn’t just delete it as a first option, if possible do a recovery install and then cleanly uninstall it from the org. That would be my first option.
I don’t see
CN=Configuration, CN=Services
Launch ADSIEdit.msc and navigate to CN=Configuration, CN=Services, CN=Microsoft Exchange, CN=, CN=Administrative Groups, CN= , CN=Servers, CN=, and then delete the server object.
Hi ckara, when you open ADSEdit and connect to AD make sure you choose “Configuration” as the “well known Naming Context” to connect to.
Thank you Paul. This article has a great value. Saludos from Monterrey, Mexico.
Respected Paul i install exchange server 2010 but at final step of installation i got this error at hub transport MS EXCHANGE TRANSPORT FAILED TO REAACH STATUS RUNNING ON THIS SERVER i am working on vmware my ad dhcp dns on same virtual machine plz plz help me
Check for clock skew between the Exchange server and the DC. This is common in virtualized environments.

Did some search on technet and found out solution to previous problem.
looked at registry path HKLM\software\Microsoft\Exchange server \V14
- deleted “Setup” nodes under V14
- Reboot the server
- Run setup.com /m:recoverserver
and the setup started but at the step when it says installing mailbox role it gave me another error given below

Hi,
After a power outage at our datacenter we are experiencing lots of errors:
1. Some users cannot get into outlook. When I try to check their inbox it looks like the object does not exist. Their bounceback also suggests they do not exist. They do still have an exchnage object in AD
2. Some users can receive mail on their phones via push mail and some users cannot
3. Some users have emails missing
4. Various other issues like viewing calendars and owa access and such.
I tried restoring the database to a point before the outage and these issues still occour which would suggest it is not a database issue. I have since restarted all exchange servers and this has not fixed the issue.
Any ideas what this could be?
In ad we have an ou called Microsoft Exchnage hosted Organizations. It was automatically created when we installed exchange with the /hosted switch
Now evertime we create an org it creates an OU under that with the org name. In that OU when you create an new mailbox it creates an object in there for the mailbox. It looks like a user object. This is the object I was reffering to.
When I do the check mailbox in EMC thats what suggested it didnt have only, However when I run get-mailboxdatabasestatistics it shows in there. Also it lets me disable the mailbox. I have since disabled one of the mailboxes and connected it to another object I created by doing a new-mailbox command and then disabling its mailbox and attaching the other one(not sure if that is the right way to do it). Since connecting it to the new mailbox I created I cannot get it to match the name of either the original email address or the second I created in exchange. I’m not sure which address I should have tried.
Any suggestions?
I don’t do any work with hosted installs so I can’t offer you any advice there sorry.
