Are you sure that the Microsoft Exchange System Attendant Service is running.

I had the same issue in an exchange lab. After starting this service, as actually also the error message implies, everything worked fine.

The Microsoft Exchange System Attendant service is primarily a collection of subcomponents that work together to proxy Active Directory requests and to regulate internal Exchange Server functions. It is critical to Exchange Server’s performance, since many Exchange-related services will not function without it.

In Exchange 2003, for example, you cannot mount the databases unless the Exchange System Attendant service is running. The Exchange information store is also dependent on the Exchange System Attendant service. Even in previous versions of Exchange Server, various Exchange-related services fail to start unless the Exchange System Attendant is running.

The appearance of an Event 1005 in the application log is usually accompanied by the problem of the System Attendant not starting.

a.. DNS Issues. For example, DNS may not be configured correctly on the Exchange Server. This is particularly possible if there is more than one Network Card on the server.
b.. System Attendant Service configured to start with some other account and not the Local System Account.
c.. Exchange Domain Servers Global Security Group may be missing, may have been moved to another container or may have permissions on it modified.
d.. File and Print Sharing may be disabled. NetBIOS over TCP/IP may be disabled.
e.. NetBIOS TCP/IP Helper Service may be disabled.

User Action
a.. Check DNS Settings on the Server and ensure that they are correct.
b.. Ensure that the System Attendant Service is starting with the Local System Accountant.
c.. Ensure that the Exchange Domain Servers Global Security Group is present in the USERS Container.
d.. Ensure that File and Print Sharing and NetBIOS over TCP/IP are not disabled.
e.. Ensure that the TCP/IP Helper Service is not disabled.

Issues that might cause this problem:

a.. Domain Name System issues. For example, DNS may not be configured correctly on the Exchange server. This is particularly possible if there is more than one Network Card on the server.
b.. System Attendant Service configured to start with some other account and not the Local System Account.
c.. Exchange Domain Servers Global Security Group may be missing, may have been moved to another container, or may have permissions on it modified.
d.. File and Print Sharing may be disabled. NetBIOS over TCP/IP may be disabled.
e.. NetBIOS TCP/IP Helper Service may be disabled.

User Action
