Pass-through authentication (Single Sign-on) provides the ability to authenticate yourself automatically in Network Configuration Manager using your current Windows system username and password. You would not need to manually enter your windows credential to log-in to Network Configuration Manager webclient.
Run the script NewComputerAccount.vbs present under NCM_Home\conf\application\scripts to create a new computer account cscript NewComputerAccount.vbs account_name /p password /d domain_name
To reset the password for an existing computer account, run the script SetComputerPass.vbs present under NCM_Home\conf\application\scripts to create a new computer account cscript SetComputerPass.vbs account_name /p password /d domain_name
Ensure that the password you give is compliant to the password policy for that domain. Do not use the New Computer Account option present in AD native client which will not allow you to choose a password. If you face problem running this script from Network Configuration Manager server, copy the script to the domain controller machine itself and try running it.
