If the Use current name and password check box is not selected, credentials must be provided when the Microsoft Exchange MTA attempts to connect to the remote server. To accomplish this, the local MTA will use the account information in the RAS Override property page of the Dynamic RAS Connector. The information supplied in the property page should be an authorized account in the remote system that can both log on to the remote system and access the Microsoft Exchange Server directory database with full permissions.
You can create Windows NT accounts to be used in the RAS Override property page of the Dynamic RAS Connector. To configure an account, use the Windows NT User Manager for Domains.
Complete the following steps to create Windows NT accounts.
In the three-server example described earlier, the following accounts could be created:
Note Although you can choose any name for the account name and password, as mentioned earlier, the names must be identical for each domain.
After you create the Windows NT accounts, you must grant these accounts dial-in access.
Complete the following steps to grant dial-in access to Windows NT accounts.
After you grant the accounts dial-in access, you need to grant these accounts permission to access Microsoft Exchange Server.
Complete the following steps to provide Windows NT accounts Microsoft Exchange Server permissions.
