SUMMARY
=======

If the disk that a Key Management (KM) Server password is located on is lost or
damaged, and the password on the disk is unknown, the following procedure can be
used to reset the KM Server password.

MORE INFORMATION
================

1. Have the users decrypt any encrypted messages (or else they will not be able
  to read them once they get a new security key). They can do this manually or
  use the bulk security tool SECTOOL.EXE (included with the Microsoft Exchange
  Resource Kit) to decrypt them all at once.

2. Run KMSERVER -u (you must use lowercase) to remove the Microsoft Exchange Key
  Management Service.

3. Remove the directory where the Key Management server was installed.

4. Reinstall the KM Server software to generate a new key for encrypted
  messages.
