Accidentally renamed domain to Workgroup

By jkenneyjr ·
Hi - I was looking into how to change a domain computer to a workgroup computer and accidentally changed a domain to a default Workgroup. Now, I can't log into the computer with the old username and password. Nobody knows what the admin password would be and these were all set up before I got here. Any suggestions?

Also, the machine is a Toshiba Tecra 8600 and it has a bios password, which I know. I can't seem to get into the bios to set up the machine to boot from the CDrom drive. I follow all the instructions I find online but no bios setup. It goes directly to the Win2000 setup screen. Any help is much appreciated.

Well, it sounds as if

you should take it to a shop or have tech support at your business fix the problem. You will need access to the administrator account, or any other local (not domain) account to correct the problem.

I have thought of trying the third party password resets but I can't get the machine to boot to a CD. There is no floppy drive (I am old school). Any idea why I can't get into the Bios? I have the Bios password but all attempts to get into it fail . . . it just goes straight into the Win2k startup.

what about a USB floppy?

by w2ktechman In reply to I am tech support . . .

they are not that expensive. Other than that, look up the manufacturer of the system and find out how to reset the BIOS PW to boot to cd.

if you know the administrators user name

by CG IT In reply to Accidentally renamed doma ...

you can try using that with a blank password.

typically when a computer is joined to a domain, the domain administrators account is added to the local machine computer administrator's account basically overwriting it.

once you log on, you can change the password or join the computer back to the domain.

if you try the domain administrator's account with a blank password and that doesn't work, then you can try using any of the administrators password reset tools available on the internet.

Here is how to

Change the Boot order or get into the BIOS.
What is the exact model number? Toshiba does not list the 8600 as belonging to the Tecra line (unless it was hiding in the archived section).

From the Toshiba support site;
This bulletin documents the several different methods for gaining access to the BIOS Setup feature of most models of Toshiba computers. These setting are stored in non-volatile CMOS memory, hence the alternative term "CMOS Setup". The settings are managed by a utility program built into the computer's BIOS (Basic Input/Output System).

For Toshiba desktop PCs and servers : Press and hold the F2 key immediately after turning the computer on (during the Power-on Self Test (POST)).

For Toshiba notebook PCs manufactured since the introduction of Windows XP, one or more of the following methods will be effective:

Toshiba Hardware utility method: Run the Toshiba Hardware utility from the Toshiba Console. It may also accessible (as 'HWSetup') from the Windows Control Panel. Changes to some of the settings will require re-starting the computer. This method is the only way to access the BIOS settings on some notebook PCs (Satellite 5000 series, for example). (For these machines, pressing and holding the F12 key immediately after powering-on the notebook will allow you to alter the notebook's boot priority.)

If the Toshiba Hardware utility is not present, try the F2 key method and the Esc key method (see below). The Toshiba Hardware utility may be downloaded from the Toshiba support website at
If the computer is fully off, and/or to avoid having to re-start it (and Windows), use one or the other of the following two methods. The PC will have to be truly off (not suspended, or in standby mode, or in hibernation mode). If an external keyboard is attached to the notebook (either directly or via a docking station or a port-replicator), disconnect it until you have completed this procedure.

F2 key method: Turn the computer on. If you see an invitation to press the F2 key to enter Setup, do so. The Setup screen will appear.

Esc key method: Turn the computer on. If you do not see a prompt to press the F2 key, then immediately press and hold the Esc key for three seconds, and then release it. When prompted to, press the F1 key. The Setup screen will appear.

Sorry model number typo

by jkenneyjr In reply to Here is how to

Hi - thanks for the help. The model number I mistyped - it is a Tecra 8200.

It is very strange at startup. The Toshiba oem screen flashes briefly - I hit the F2 key at that time. After that brief moment it goes right to a password screen. I type in the password and hit enter while holding down the ESC key. It says to press the F1 key to continue. I do so, then the Toshiba oem screen flashed briefly and it goes right into the windows startup, ignoring any attempt at getting into the Cmos or bios or any startup screen. The only command that the machine heeds is the F8 key once the windows start up begins - which is of no help. Frustrating!
