My user accounts are not working right.The main account (administrator) works fine.The other account (administrator) lacks some of the core system functionality, such as audio controls - even though I just reinstalled them.Plus, I tried to make a new user account, and I was not able to enter a valid domain. "Browse" gave me no options. And when I typed in the domain of the other user accounts, I received the error message "The user XXX/XX could not be added because XXX/XX does not exist."What is going on here? How do I fix it?1 person needs an answerI do too

if this computer is in domain then first thing you need to do is adding the computer in domain they try to log on .
