The title says it all...
Every account on the domain is locked out. I can not get in to unlock any of them.
This is a NT4.0 domain.

My primary concern is How do i get in so that i may unlock the accounts?

THis is urgent for me, so i am giving as many points as i can.

Thanks,
Hudson

Since time is of the essence, I'll drop a quickie here then go look for details.  There exist small floppy-based linux distributions with a utility to blank or change any passwords on an NT based system.  I'll be googling for a specific url for you.  I carry such a floppy with me in my cd case for the times I am to fix a computer and the admin is on vacation or quit.

and http://home.eunet.no/~pnordahl/ntpasswd/bootdisk.html is the one I used on XP and 2k before.  Should work on NT as well according to the author of the program. Good luck!

Hi,

Ok if I'm on the wrong lines here then I apologise as I'm win2k rather than NT - however - doesn't the account lockout policy have a fixed duration after which time you should be able to get back in? If I were you I'd consider isolating the network from external sources (or maybe even internal) as quickly as possible then proceed to examine whatever event/audit logs that you have in place to try find out what happened. It sounds possible that this is some sort of malicious attack, either way you obviously need to figure out exactly what's going on,

I'd maybe be tempted to review your lockout policy so that you can get back in more quickly until you can resolve this , malicious user activity or virus perhaps?

pull the cat-5, run the nix boot disks, get back in, and asess the situation (network cable still unplugged).  If you're compromised, you better reformat/reinstall, and don't restore executable files from backup media.  If you were r00t3d by someone good, you're done if you do.  If it was some other reason for getting locked out (human error or a stupid script kiddie pseudo-r00ting you w/ no backdoors), then you're in good shape simply booting the disks I mewntioned previously.....checking start/all programs/administrative tools/event logs/ or settings/control panel/event log/ once back in would definately be worthwhole tho.  If you enen have ONE hair stand up safing "this is an attack" you better follow Deb's advice and pull the ethernet plug before going farther.  If you've been r00ted you better plan on a reformat/reinstall.  If I r00ted your NT system, you wouldn't see *my* processes in task manager and I would be free to do whatever I wanted as user: SYSTEM..  Safe mode or not.

Sry for the delay... got hit by a hurricane.

I was able to find our network admin account password and resolve the issue. one of the PC had an IRCBot that was hammering the administrative shares locking accounts out. we have resolved all issues.

Thanks soooo much for the help.

awarding points and again, Thank You!
