If it is running acs ver 4.0 on windows, then it is not possible. With ACS v4.0 all the configurations have been shifted from registry to a database file thus increasing the security in ACS. So as of now there is no way to recover the lost Admin password in ACS v4.0, cause no setting is in registry, all settings are in SQL database.
So need to reimage it ...
If it is acs windows 3.3.4 or below then you need to make registry change,
login to ACS machine as administrator..
Go to start ===> run ===> regedit
Click on HKEYLOCAL machine ===> software ===> cisco
===>CiscoAAAv3.2===>CSAdmin===> and delete all administrative users defined by
right clicking into the administraor folder.
Now login locally to ACS and it should not prompt you for password.
For a best practice make sure that you have Allow automatic login is checked
This will not prompt you for password if you are logging in locally from ACS mahcine.
If it is appliance then you need to use recovery cd to reset admin password.
I guess that I'm missing something here. You can access ACS from the web browser on the server where ACS is installed without credentials, as long as you have a logon to the system. Then you can change the admin accounts.
Thats fine for http://127.0.0.1:2002 unless you've got the "allow automatic local login" de-selected under Administration Control-->Session Policy Setup. If that is not selected you're looking at re-installing.
Login to the FXOS chassis manager.
Direct your browser to https://hostname/, and log-in using the user-name and password.
