I'm running through the paces on a testbed where I'm introducing a Domain Controller to an existing Workgroup.
The DC Server was working fine with GTA until I promoted it to the DC role.
Now, when I try to change (or confirm) the password using the system tray icon Unattended Access \ Update Stored Password, I keep getting the response: "The username and password you entered is invalid".
Yet, I can use the username and password if I logoff and logon again while remaining in the GTA session!!
I have tried:
username
Servername\username
Servername.domainname\username
When starting a new GTA session, I don't see the banner "you have a stored password".
Yet, when entering the correct password *here* it works just fine.
