An error caused a change in the current set of domain controllers……

If you are in the middle of migration and after decommissioning couple domain controllers and start having similar problems listed in this blog keep reading it. Some of the finding listed here may save you a support call to PS (-:

You have successfully decommission some of the domain controllers yet exchange is still complaining about it.

possible cause:

• Check DNS to make sure name servers tab , the old DC is not listed there , if there is delete the record.
• Check DNS to make sure there is no A record pointing to decommissioned DC if there is , delete the record.
• Make sure TCP/IP properties on the exchange server configured correctly and pointing to valid DC/DNS/GC server.
• If you are receiving fallowing or similar errors upon opening EMC

• An error caused a change in the current set of domain controllers it was running the command “Get-FederationTrust”
• HTTP server status WinRM….

• The profile you logged into Exchange server might be causing these issues, log out , log back into DC with another admin credentials and delete the profile giving you above errors. ( roaming profile). Let’s say you have account called Exadmin and this account has been used to log into exchange server. You need to delete the roaming profile for “Exadmin” and on first logon Windows will create new roaming profile
• On the Exchange server open EMC click on “Collect organizational Health data”

Go to event logs and under application logs make sure there are no more errors

Error: Mailbox database contains one or more mailboxes arbitration mailboxes…….

If you have completed Exchange 2010 installation and opened EMC right after it, you should be facing with default databases with some random number as shown below…

Now if you are like me this will not make you happy and you will want to rename this DB something will make more sense to you, such as DB1, however you will realize you cannot change the name of the DB and this will drive you nuts each time you open EMC (-:, so let’s nuke it and create another one.

• Now just fallow simple steps , Open EMS ( Shell)

Figured out the name of the databases, you need to create least one more since you will move users from this DB into another one and delete is once there is no mailbox in the first database.

Get-Mailbox -Database

Get-Mailbox -Database db1 -Arbitration | ft -wrap -auto

New-MoveRequest -Identity "DiscoverySearchMailbox {D919BA05-46A6-415f-80AD-7E09334BB852}" -TargetDatabase DB2

***Pay attention little carrots and semi columns are going to make difference , so you have to use exactly same name on the New-MoveRequest CMDLET***

• You can use notepad to prepare the CMDLET

Get-Mailbox -Database db1 | ft -wrap –auto

Get-MoveRequest

• Arbitration mailboxes are used for managing approval workflow….
