XADM: How to Determine the Organization, Site, and Computer Name

If the Microsoft Exchange Directory service fails to start, either because the computer name has been changed or there is file corruption, you need to determine the organization name, site name, and possibly the computer name. To re-create the same machine configuration, you must determine the computer name. To determine these names, you need to find the file called "Exchange Server Setup.log," located in the root of the disk drive where the Microsoft Exchange Server is installed.

To determine the organization, site, and computer name:

1.	In the root directory of the computer running Microsoft Exchange Server, locate a file called "Exchange Server Setup.log."
2.	Using Notepad or another text editor, search the log for the first occurrence of "Creating." This will display the organization, site, and computer name. Because the file is appended each time Setup is run, there may be multiple Setup details in the file.
3.	To display the latest log, go to the bottom of the file and search upwards for the "Creating Object" line. In the "Creating Object" line, the organization, site, and computer names are displayed as shown below: /o=<Organization>/ou=<sitename>/cn=configuration/ cn=servers/cn=<computername>
