You cannot open the Exchange Management Console in Exchange Server 2007

You cannot open the Exchange Management Console (EMC) in Microsoft Exchange Server 2007. Additionally, you receive the following error message:

Active Directory server dcservername is not available Error message: A local error occurred


This problem may occur if the Windows profile of your user account is corrupted.

This problem may also occur if Exchange Powershell cannot connect to a server that has stored credentials. Exchange Powershell must connect to the server to retrieve forest information that is incorrect or that does not have correct permissions.


To resolve this problem, use another domain user account to try to open the Exchange Management Console. This account must have administrative credentials for the Exchange server. If the Exchange Management Console can be opened successfully, follow these steps to rebuild the questionable Windows user profile:

1. Use a new account to log on to the computer on which the corrupted profile resides.
2. In My Computer, locate the “Documents and Settings\user profile” folder.

Note user profile is the name of the corrupted user profile.

3. Back up all the content in this folder to a safe location.
4. Delete this folder.
5. Log off the computer.
6. Log back on to the computer by using the account that had the corrupted profile. The Windows profile for the user account is re-created.

If this problem occurs when you are logged on as an administrator, follow these steps:

1. Click Start, click Run, type control keymgr.dll, and the click OK.
2. Click Back up, and then follow the instructions to save the current entries.
3. Delete any entry that matches the names of the Exchange servers and domain controllers in your organization. Typically, you want to clear all entries.
4. Try to open the Exchange Management Console.
