Yes. Domain admins have Local Administrator privileges and can reset passwords on all local user accounts.

Use the "net user" command to reset the password/enable the account on the machine for which you have forgotten the local admin password.

Or just open the Local Users and Groups MMC and change the password there.

Did net user commend but only listed the domain user not the local [I changed the password on that user, it changed the password of the domain login not of the local)

Would you give me little more guidance where in the console I will find this option.

PS there is a work around way doing it via GPO. But prefer doing it correct way.

The way doing  it thru the installation dvd and cmd is only used a last option

Right click the start button, select Manage Computer, from there, you can get to the Local Users and Groups portion of the computer management console. The users listed there are the local users on the server. Change the password for the local administrator there.

It's a DC...domain controllers have no local users. Are you talking about the directory services restore password?

As Adam said..it's a DC.  When you did my suggestion, you changed the password you needed to.
