Odd domain controller errors in Exchange 2010 EMC after some DC moves.

After demoting some domain controllers, Exchange was functional and healthy, but we were seeing the occasional error when loading recipient lists, or drilling into a specific mailbox's settings such as the one below:


I would try a second time and get to the data, but the issue was annoying. Then I found this here:

The fix for me was not the highlighted one in that thread, but Adam Miceli's comment:

"Delete this file: c:\users\<specific user>\appdata\roaming\microsoft\mmc\Exchange Management Console"

This COMPLETELY worked and we no longer receive the above errors.
