Accidentally changed domain to a workgroup...

[Matt Veino]

....and now I can't login!

I wanted to change the computername, but the domain I was in wasn't
letting me. So, stupidly, I switched it over to a workgroup, a random
workgroup I made up, "blahblah" .

But when I restarted, now there's obviously no "domain" box on the login
screen.

And now, I can't login with my normal login/pass (i'm an administrator,
too..) ... And I'm unsure of what other login/pass would work.

Anyone have any suggestions how I can get back into the OS so I can
change it back to domain?

Thanks.

Hi

Log on with the local Administrator account and add the computer back to the
domain.

If the Administrator's password is not blank, and you don't know what it is:

If that doesn't work out, you might try to reset the local Administrator
password with one of the methods mentioned here:
