Windows login help needed ASAP!

post #1 of 19
Thread Starter 
Alrighty, so here's the deal. You can respond here, or PM me directly, I don't care. This thread MAY be borderline TOS abuse, and I don't want that. I just need help to stop this issue, and I don't know where else to turn. Mods, if this top line here doesn't sound good to you, feel free to edit my post.

With that being said.....
I'm the admin for my house (obviously). However I'm also the admin for my parent's network at home. And my sister has figured out a way to bypass my security. The administrator account, and my dad's account on his laptop are both password protected. With passwords I don't even know mind you. The guest account is disabled. She's using windows for SURE. She doesn't SUPPOSEDLY know the password. But her "hacker" friends helped her get in through a "hidden guest account".

So how in the WORLD is she getting into the computer? What can I do to stop her? I need help here desperately....she's downloading certain "naughty" files that a 16 year old girl should NOT be downloading via Limewire.

And its not just the laptop too....she infects every PC in their house with virus's and whatever other garbage she ends up with via Limewire. I have to format all 3 of their machines bi-monthly at least because of this issue. And I just cannot seem to figure out how she's doing it.

To those of you that say just ground her:
She does NOT have access (permission) from my parents to use ANY computer other than her own (which doesn't have a NIC). Two of the PC's are in their office...which has no lock. It would do no good to lock it, she can break into locks.

Same goes for the laptop. They lock it in their bedroom during the day, but she breaks into the bedroom to get it.

This is the only thing she's really interested in breaking into things for...internet access. But she's not supposed to have it because of this EXACT reason!

So? Can anybody guide me here as to what she can be doing to gain access to the machines? Like I said, I've proven today that she actually IS logging on with their names. But they change their passwords religiously now, but she's ALWAYS able to get in!

Help? Oh, and to those that read this whole thing....we're talking XP Professional here.

I know there are password crakers out there for Windows, I guess she has one?

Try a BIOS password and a bootup password (easy to bypass with a MoBo BIOS reset on the desktop, a little harder to do on the laptop).
Set the initial (or even only) boot device to HDD with the OS on it. Most of the craks rely on booting up with a CD or usb stick to run a live linux to crack it.

Thanks, I'll give that a try out next time I'm out there. Didn't even think of that!

Maybe it's the hidden admin account?
You can access it if you boot into safe mode. Search around to find ways to disable it if you don't want people going on it.

I've already stated (I think)...the "hidden" admin account named "administrator" is also password protected, and the P/W is changed regularly. Only things I can come up with is some sort of a "hack" to get the password before logging in, or a Live Disc. Those are the ONLY things I can think of.

Also, do they have a router? Some Routers allow lots of tweaking to "turn off" the internet at certain days and times. Pretty easy to bypass with a hard reset of the router, but could be worth a try.

I used to do this to my parents computer [before i got my laptop ]
I used a linux live cd that had a version of Firefox in it and used that
Parents had no idea [still don't] but then i found out the windows password and it ismuch faster now without needing to bother with the cd
I like the BIOS password idea - but anyone with a little bit of knowledge will know how to get around it unfortunately
