Change Passwords

Change Passwords will change the password of a local account on all targeted systems.

Targeted Computers: The list of computers that will have the password changed.

Local User Account:  The name of the local user account to be changed.  If the local user account is "administrator", the account is verified by SID.  Even if the account has been renamed, use "administrator" as the name to change the password for this built-in account.

New Password: The new password to apply.

Verify Password: Verify the new password to apply.

Random Password: If Random Password is checked, it is not necessary to specify a new password because cPWD will automatically generate and apply a random password that is C2 Security compliant.

Min.Length: If Random Password is checked, then the minimum password length must be specified. The minimum password length should be set based on your Active Directory Security Policy. The length of random passwords that are generated by cPWD will be between the minimum length plus 5. For example, if you specify a minimum length of 15, the length of any given random password will be between 15-20.

A password should NOT be used with "LocalSystem".

Password: The password of the domain account used to logon.

History Maintenance

All computers and associated history files are maintained in a folder named "COMPUTERS\%COMPUTERNAME%\%COMPUTERNAME.TXT" that is automatically created as computers are added to cPWD.  By default, the "COMPUTERS" folder is created in the same directory where cPWD.EXE is executed.

It is recommended that this folder be protected, as it contains the actual account names and passwords cPWD applied.

Each time cPWD is executed against a list of systems, a status web page is generated displaying success/failure results.  Clicking the "X" or "CHECK-MARK" from this web page will open the history file for that computer.  This web page (CPWD.HTM) is overwritten each time a list of computers is scanned.

Optionally, you can also navigate to the "COMPUTERS" folder and locate/view the history file for any computer.

Working with Multiple Domains

cPWD uses your existing credentials when searching, modifying or administering Active Directory objects or remote computers on the network. To access other domains on your network, right click cPWD.exe and perform a RunAs command against the executable, then specify the proper domain credentials.

Encrypted Password Changes over the Wire

When using cPWD to change passwords on remote computers, the NetUserSetInfo protocol is used. This protocol has been tested and proven to be secure when changing passwords. IT DOES NOT DISPLAY THE PASSWORD IN CLEAR TEXT OVER THE WIRE.

Error Message when executed on a domain controller

When you attempt to execute cPWD on a domain controller, you receive an error message stating "665: Specified domain is not a trusted domain". Do not execute cPWD directly on the domain controller, instead run it from a member server or workstation.
