Warning: I am the de facto IT person for a very small company so please don't respond to my questions with "Call your IT department."
Issue # 1: I have a user today whose Win 7 desktop suddenly lost domain access and he was not able to log back into his account. It threw an error to the effect of "trust relationship has been lost."
Issue #2: I tried to log into the local machine so that I could leave/rejoin the domain but received the error message "Logon server not available." It's as if it's looking for the domain in order to validate the local login credentials or something??
I was advised to clear the DNS entry and remove the computer from AD. I did those but now when I try to log into the local machine, I get a persistent "invalid login/password" error. I *know* I am entering the password correctly.
But, just to be certain that I am not crazy, I used the installation disk to access the command prompt and activated the built-in administrator account. I changed the password for the secondary administrator account which I created on initial installation but still get the login/password error when I try to login to the local machine. So, I then created an entirely new user and added it to the administrators group.
I give access to the new administrator using: net share concfg*C:\/grant:newuser,full
But I get a syntax error. It wants me to enter sharename=drive:path so I reenter as:
net share concfg=C:\/grant:newuser,full
and it gives me the error: service name invalid. How can net share be an invalid service?
Can someone please help me with any or all of these issues? Thanks in advance.
