ADMT Password Export Server Error: Invalid Password!

KB ID 0001355


Seen when trying to install the ‘ADMT Password Export Server Service’, whilst doing a domain migration;

ADMT Error-supplied-password-does-not-match

Invalid Password!

The supplied password does not match this encryption key’s password. ADMT’s Password Migration Filter DLL will not install without a valid encryption key.


At first I assumed I was suffering from ‘fat fingers‘ and just entering the wrong password, (or the Caps Lock was on.) However, it became apparent that this was not the case. I attempted to generate a new file by re-running the command on the ADMT server;

admt key /option:create /sourcedomain:{source-domain} /keyfile:”C:\PES.pes” /keypassword:{password}

Same error? The only way I could get this to work was cancel the install, then launch an administrative command window, and finally running the install, ‘en-US_pwdmig.msi’ file from within that Administrative Window.
