Locked out from Windows xp professional machine, even local account doesnt work,safe mode fails to.
I recently removed a computer from the domain and i try to log in locally but it fails everytime but i know my login and password re correct, also where it prompts you to enter your user name: and password: the box where you enter your domain is missing.I have tryed to boot up in safe mode but it still doesnt let me log on, i have also tried running the xp disc for system recovery but it prompts me to enter a password but no username so i assume its the defualt administrator login but when i enter the password for my login it doesnt work and after 3 attempts shuts down.Its not on the network when i view it from the sbs console but when i view the network from windows explorer i see the computer name and can access its shared files and printers and faxes, does anyone have a solution to my problem ?

"You cannot log on after you remove the computer from the domain" < http://support.microsoft.com/kb/317049 >Unfortunately the above article usually only explains the problem and does not help much. You need to log in and perform a system restore to recover from this but since you've broken the trust with the domain, you must use a local login. The best candidate is the built-in administrator account. From the login screen, hit Alt-Ctrl-Del twice and you should be able to type in "administrator" as the user and leave the password blank (assumes that nobody has assigned a password to this account in the past). If this works, either perform a System Restore to a point in time before you removed it from the domain or just create new local users if you don't want it on the domain.Failing this, there is a way to manually replace registry files with backups but it's messy.HTH, JW

There is no way for me to log on locally either, im 100% sure that my password is correct, i have tried logging in as administrator and leaving the field blank also,nothing,cant do anything, i even tried using the windows xp disk to run repair but it prompted a password and i used the one for the defualt admin account and it didnt work it seems like its impenetrable.

In a situation like this, and assuming you can't get your machine re-connected to the domain, your only option is to boot from a bootable CD/DVD and restore the registry manually from a point in time before you removed the computer from the domain. Hopefully the cached logins will be restored and you will be able to log in. My preference is to boot from a Live Linux CD such as Knoppix or Ubuntu . If you choose Ubuntu, take care not to install it but select the "Try me" option when booting. You can create other Windows-based boot disks such as Bart PE or Ultimate Boot CD for Windows (UBCD4Win). UBCD4Win has a utility that will do all the steps automatically: http://www.technibble.com/how-to-fix-windows-registry-hive/ > (courtesy Daavee)Warning: the Windows-based boot disks require a Windows XP install CD as a part of the build process (Microsoft Copyrights)Otherwise, once you build the bootable CD, boot from the CD/DVD and follow the instructions in the following KB article:"How to recover from a corrupted registry that prevents Windows XP from starting" < http://support.microsoft.com/kb/307545 >Since you booted from a bootable CD, you can ignore the warnings about OEM systems and proceed beginning at Part 2, Step 6. Move, copy, and rename the files as directed using commands native to the OS CD that you booted from (usually Right-Click -> Copy, or Right-Click Paste, or Right-Click -> Rename). Pick a Restore Point (RP) directory dated before your mishap. You won't have to reboot between Part 2 and Part 3, but at the end of Part 3, you must shutdown, remove the CD, and reboot your machine. If you successfully log in at this point, don't forget to do Part 4 (System Restore).HTH & Good Luck, JWPS: After booting from the CD, you might take the opportunity to back up some of your files to a USB drive.
