EMC error: An error caused a change in the current set of domain controllers.

When opening Exchange Manangemnt Console you get the following error:
An error caused a change in the current set of domain controllers. It was running the command ‘Get-OrganizationConfig’.

In the application log you get the following error entries:
Event ID: 4
Source: MSExchange Configuration Cmdlet – Remote Mamagment
General: Task Get-ExchangeServer writing error when processing record of index 0. Error: Microsoft.Exchange.Data.Directory.SuitabilityDirectoryException: An Active Directory error 0x51 occurred when trying to check the suitability of server ‘dc.mydomain.com’. Error: ‘Active directory response: The LDAP server is unavailable.’ —>

Event ID: 5
Source: MSExchange Configuration Cmdlet – Remote Mamagment
General: Task Get-ExchangeServer throwing terminating exception at stage Microsoft.Exchange.Data.Directory.ADTransientException: An error caused a change in the current set of domain controllers..

This happend to me after a domain controller was removed and replaces with a new one on the same site as the Exchange 2010 server.

To solve this problem close the EMC. Delete the fileĀ  C:\Users\%username%\AppData\Roaming\Microsoft\MMC\Exchange Management Console. Open EMC again and you shold not get the error message again.

    Hey, this sollution seemed intreaging – I have this exact same problem, though no error on MMC startus, only on access latest data in the default site of mms on connected server. Itfetches the data but when it tries to write/save it, an error is thrown and error with id 4 is posted in error log. I tried your sollution and still the same, just to let you know…
