An Error Message Is Displayed During the Installation of Exchange Service Pack 4 (285297)


The information in this article applies to:

  • Microsoft BackOffice Small Business Server 4.0
  • Microsoft BackOffice Small Business Server 4.5
This article was previously published under Q285297

SYMPTOMS

When you attempt to install Microsoft Exchange 5.5 Service Pack 4 (SP4) on Microsoft Small Business Server, you may receive the following error message:
Processing file D:\Eng\Server\Setup\I386\Server.ins, at or near line 781. No mapping between account names and security IDs was done. Microsoft Windows NT ID no: 0xc0020534

CAUSE

This behavior can occur because the security identifier (SID) of the Exchange Security account is examined while the Service Pack is being installed and changes to the registry are being made. If the SID cannot be obtained or the Service account is located on another domain separate from the users accounts, the installation of the Service Pack is unsuccessful.

Small Business Server is designed to be a single-domain or single-site installation. If the Exchange Services Startup account has been corrupted, the Security Service account seems to be in a different domain.

RESOLUTION

To resolve this behavior, you must perform the following steps:
  1. Start Exchange Administrator.
  2. Select the configuration container.
  3. Display its properties by pressing ALT+ENTER or on the File menu, click Properties.
  4. Click the Service Account Password tab.
  5. Observe the account name. It should be in the format of domain\Administrator. If it has an incorrect domain name or it is ".\Administrator", you must reset the Service account.
  6. In Control Panel, double-click Service.
  7. Select the Exchange services one at a time.
  8. Click the Startup button.
  9. In the Logon as section ensure that the account name is domain\Administrator. If it is not, click the Browse button (the button with two dots next to the account name) and click the Administrator user (not the Administrators group).
  10. Repeat steps 8 and 9 for each Exchange service.
  11. Use the Small Business Server Console to reset the Administrators password.
  12. In Services, stop the Exchange System Attendant. This should stop all dependent Exchange services as well.
  13. Restart in this order: the Exchange System Attendant, Exchange Directory, Exchange Information Store, Exchange Mail Transfer Agent, and any remaining Exchange services that have already started.
  14. Verify in the Exchange Administrator that the Service account name is now in the correct domain\Administrator format.
  15. Install Exchange 5.5 Service Pack 4.

MORE INFORMATION

Typically, the Exchange services on a Small Business Server-based server start up using the Small Business Server Domain Administrator account. If the startup entries become corrupt and display an account name, such as, ".\Administrator", the system considers this account to reside in a domain other than the actual Small Business Server-based domain. When it cannot locate a valid SID for ".\Administrator", the Service Pack installer is unsuccessful and displays the error message.
