To use Legacydn.exe, follow these steps:
  1. Obtain a copy of Legacydn.exe from the Microsoft Download Center. To do this, visit the following Microsoft Web site: http://www.microsoft.com/downloads/details.aspx?familyid=5ef7786b-a699-4aad-b104-bf9de3f473e5&displaylang=en
  2. For detailed information about the tool, review the Legacydn.doc file that is included with Legacydn.exe.
  3. Copy the Legacydn.exe file to the Exchange 2000 Server or Exchange Server 2003 computer, and then double-click the file to open the graphical user interface (GUI).

    If you use Legacydn to make changes to the legacyExchangeDN values in a production environment, you can no longer start any Exchange database.
  4. If Legacydn.exe is not running in read-only mode, this means that you are working in a lab environment and have used the FORCEWRITE command-line option. In this scenario, you can make changes to the legacyExchangeDN values by using the Legacydn interface.
  5. When you run Legacydn.exe, a log file named LegacyDN.log is created to record the startup search information and any changes that you make.

    You can change the logging level of Legacydn.exe from Normal (0) to Verbose (1). Normal (0) is the default setting.
The following list describes the command-line options for Legacydn.exe:

LegacyDN [/DUMPAGS] [/LOGLEVEL <logging level>] [/SERVER <preferred server name>] [/USER <username>] [/PASSWORD <password>] [/FORCEWRITE
  • /DUMPAGS. This option dumps the administrative group list to the log file.
  • /LOGLEVEL. The default logging level is 0 (Normal), and you can also set the logging level to 1 (Verbose).
  • /SERVER. Fully Qualified Domain Name (FQDN) of preferred Windows domain controller
  • /USER. User name
  • /PASSWORD. Password
  • /FORCEWRITE. Must be used to run in edit mode.
Note To view this list, you can also run Legacydn.exe with the /? command-line option
