SYMPTOMS
If you use the Microsoft Exchange Server Setup program to join an existing site, when you type the server name of the site that you want to join, a dialog box displays the service account that the existing server is currently using. Sometimes it displays only the service account name instead of both the domain name and the service account name. Setup then stops, and you receive the following error message:

Microsoft Exchange Server Setup

Processing file \server.ins, at or near line 276

No mapping between account names and security Ids was done.

Microsoft Windows NT

ID no: 0xc0020534

This behavior also occurs when the two servers are in the same domain, and the new Microsoft Windows NT-based server is set up as a backup domain controller (BDC) of this domain. When you use the service account to log on to the new server, the behavior remains unchanged.



CAUSE
This behavior can occur when the Exchange Server account, in any of the Microsoft Exchange-related services, is set to  and not  \.

When Setup seeks a service account to continue the progress, it gets the service account name from the existing server's service logon account, which, in this case, is set to  only. The domain name cannot be retrieved. This prevents Setup from finding a proper domain controller to verify the security identifier (SID).



RESOLUTION
To resolve this issue, follow these steps:
 * 1) In Control Panel, double-click the Services icon.
 * 2) Click each Exchange Server-related service, and then change the account so that it is formatted as  \.

After you have ensured that the service account names in all Exchange Server-related services are formatted correctly, restart Setup. The new server can now successfully join the existing site.
