Locked myself out of windows xp

[englishpremier]

Removed myself from our work domain (don't know why really) but stupidly thought that i had a local account on the laptop, which it seems i dont.

Now of course i cant log in.

I've tried resetting the administrator password using a linux live cd and chntpw, which all went well in linux, but when i loaded windows back up, i still couldn't log in (as Administrator with a blank password).

Any idea? Or am i going to have to grovel on Monday morning?

Set the Administrator password to a actual password not blank. Something like 'xxx' or 'password'. Blank passwords won't work.

Nah doesn't work. When i boot up, my old domain username is still in the login box.

Yup you're screwed, unless you have another machine and copy of server to mimic your old domain setup.

I do actually have access to another machine

I'm confused here you said in the first post. You said you removed yourself from the domain meaning there must be a local account.

What do you see on the login prompt box?

In the login box i see my old username.

I've checked using chntpw, the local accounts are:
Administrator
Guest - which is disabled
And another that is the name of the external IT company we use.

I've tried resetting the passwords to something else i.e sudo chntpw -u Administrator SAM

but still can't get in.

Kaboom i'm in. The ophcrack worked on one of the named admin accounts. Now for the setup.

How do i find and change the default Administrator account?

It's our machine we pay them for certain stuff like email, and a shared server (which is more hassle then its worth. We plan on setting up our own network.

I don't need it on the domain. Our newer laptops aren't set to a domain, we just log in ad hoc for things like shared drives.
