Hello,

I have an XP Pro "corporate" laptop that I'd like to turn into a basic home computer. It was configured to log into a domain controller.

I went to Control Panel -> System -> Computer Name and told the system it was part of a workgroup and not a domain. However, when I reboot, it still makes me enter ctrl+alt+del before I can get a login window, it forces me to put passwords on accounts, etc. Is there anything, short of reinstalling the OS, to fix this?

Thanks.

already did the important first step (switching to a workgroup and keeping a local admin) and ’s TechNet link was about demoting a domain controller (not relevant for a client PC). The remaining symptoms (Ctrl+Alt+Del still required, forced passwords, domain name showing at logon) are normally caused by local security/Winlogon settings or a third‑party logon GINA (Novell/mcGina) left on the machine — those settings don’t magically revert when the machine leaves the domain. (learn.microsoft.com)

Actionable checks and fixes (apply as Administrator; back up the registry first):

  • To stop the Ctrl+Alt+Del prompt: open Local Security Policy (secpol.msc) -> Local Policies -> Security Options -> “Interactive logon: Do not require CTRL+ALT+DEL” and set it to Enabled. On XP Home or if the snap‑in is missing, set the registry value DisableCAD under:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
DisableCAD = 1  (DWORD)  ; 1=no CAD required, 0=require CAD

    Reboot after changing. (learn.microsoft.com)

To restore the friendly Welcome screen (or control classic logon): Control Panel -> User Accounts -> Change the way users log on or off -> toggle “Use the Welcome screen.” If the classic dialog still shows the old domain name, check Winlogon values and remove/adjust any leftover autologon or DefaultDomain entries:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
DefaultDomainName   (remove or set to local machine)
DefaultUserName     (remove if not needed)
AutoAdminLogon      = 0
DefaultPassword     (remove)

MSGina/Winlogon keys control the default domain/user behavior. (learn.microsoft.com)

If blank‑password behavior or password requirements are the complaint, inspect Local Security Policy -> Account Policies -> Password Policy and Security Options -> “Accounts: Limit local account use of blank passwords to console logon only.” Domain GPOs don’t persist, but registry edits and third‑party clients can — uninstall any Novell/GINA client that reports it disabled the Welcome screen and then retest. (learn.microsoft.com)

Safety notes: always have a working local Administrator account before making changes (as noted), export registry keys before edits, and use Safe Mode to undo problematic changes.

Thanks for trying, but that doesn't help. The article is about demoting domain controllers. I want to remove a regular computer, not a domain controller, from a domain and make it a workgroup member instead (which I have done successfully).

I also want to get rid of the domain login window. This is proving more of a challenge.

One hint for anyone else who ever tries this. Make sure that there is an account in the Local Administrators group on the computer you are trying to remove before you remove it from a domain! If you don't, then you will not be able to log back in after you reboot. For the gory details, see:

And no, I didn't make this mistake...

Do you see anything in regards to Novell? When you right click My Computer and go to properties. Please select the "Computer Name" tab and please click change.

Tell me what is selected and what is listed for it's name. You want to make sure WORKGROUP is selected and if it is name it something else please. You might think it's part of the domain when it can just be part of a WORKGROUP.
