256986 Description of the Microsoft Windows Registry



SUMMARY
During the initial installation of the Microsoft Exchange Key Management Server (KMS) service, you are given a choice of whether you want to store the KMS service password on a disk or to write the password on a secured piece of paper.

If you choose to store the password on a secure disk, every time the KMS service starts you are prompted to supply the disk that contains the KMS service password.

If you choose to save the KMS service password on a secured piece of paper, before you start the KMS service you need to manually type the KMS password in the startup parameters box located at the bottom of the services window.



MORE INFORMATION
The choice that you make during the initial setup of the Microsoft Exchange Key Management Server is stored in the Windows NT registry and can be altered. Perform the following steps to make the KMS service point to a diskette instead of the startup parameters box:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

 Start Registry Editor (Regedt32.exe), and go to the following subkey:

HKEY_LOCAL_MACHINE\Software\Microsoft\Exchange\KMServer

 In the right pane, double-click MasterPasswordPath. In the String box, type the following:

A:\

 Click OK. In the right pane, double-click BackupPasswordPath. In the String box, type the following:

A:\

</li> Click OK.</li> Quit Registry Editor.</li></ol>

After you perform these steps the KMS service looks to drive A for the KMS password.

Additionally, you need to create a disk that contains the KMS service password inside a text file named Kmserver.pwd.

The Kmserver.pwd file must only contain the KMS service password that is given to the Exchange Server administrator during the initial setup of Microsoft Exchange Key Management Server.

If you remove the drive letter from the MasterPasswordPath value, you must manually type the KMS service password in the startup parameter box every time that the KMS service is started.
