In tip 2477, I explained how to reset the secure channel password using the NETDOM utility from the Support Tools.
You can also right-click the computer account in Active Directory Users and Computer and press Reset.
Once you have performed a computer account Reset, the computer must rejoin the domain.
If the NETDOM RESETPWD doesn't work, and you can't logon to the domain, perform the following procedure:
1. Log on locally, as a local administrator.
2. Open a CMD prompt and type:
NETDOM REMOVE YourComputerName /Domain:YourDomainName /UserD:DomainAdminName /PasswordD:DomainAdminNamePassword /REBOOT:103. After the reboot, log on locally, as a local administrator.
4. Open a CMD prompt and type:
NETDOM JOIN YourComputerName /Domain:YourDomainName /UserD:DomainAdminName /PasswordD:DomainAdminNamePassword \[/OU:OrganizationUnit\] /REBOOT:105. After the Reboot, log on to the domain with your domain account.
NOTE: You may perform the above operations from any Windows 2000/Windows NT computer,
by adding the following additional parameters to the commands:
/UserO:LocalAdministrativeUserOnYourComputerName /PasswordO:LocalAdministrativeUserOnYourComputerNamePasswordNOTE: Organizational unit must be the fully qualified RFC 1779 DN for the OU.
