Guest Tractor Posted July 30, 2008 Posted July 30, 2008 I am working on a client's computer. Windows comes up to Welcome screen, but no user icons are showing. I crtl+alt+del and get logon screen, user name and password does not work and administrator and password doesn't work either. How do I get into the computer to reset the passords?
Guest John John (MVP) Posted July 30, 2008 Posted July 30, 2008 Re: Logon Problem What happens when you try to logon? What error message are you receiving when you try to logon? Did you try booting to the Last Known Good Configuration or to Safe Mode? John Tractor wrote: > I am working on a client's computer.

Guest Tractor Posted July 30, 2008 Posted July 30, 2008 Re: Logon Problem I have tried both Last Known and Safe Mode. I can't get past the logon. I get error can't logon check user name and password.

Guest John John (MVP) Posted July 30, 2008 Posted July 30, 2008 Re: Logon Problem You can try this tool but I'm not sure it will help: http://home.eunet.no/~pnordahl/ntpasswd/ It sounds like the Security Accounts Manager (SAM) database is missing or damaged. If the above tool cannot help then you will have to mount the disk in another machine or use a PE boot disk to repair this. Try the above tool and post again if it doesn't help.

Guest Tractor Posted July 30, 2008 Posted July 30, 2008 Re: Logon Problem I have connnected to another machine. I can read the drive okay and I am backing up files. How do I clear the SAM database on this slave disk?

Guest John John (MVP) Posted July 30, 2008 Posted July 30, 2008 Re: Logon Problem Rename or move the SAM file out of the \windows\system32\config\ folder and replace it with the SAM file from the \windows\repair\ folder. Try and boot the machine, if the user had a System State backup restore from the backup or try restoring with System Restore, however note that System Restore does not store or restore passwords. You can also create new accounts and restore their old profiles by pointing the users profile at the registry's ProfileList key to the users' folders, see here: http://support.microsoft.com/kb/314045 The article is written for Windows 2000 but it's the same thing for Windows XP. Finally, before you do the above you may want to run a chkdsk on the drive and see if it corrects the problem. Be advised that running chkdsk may lead to loss of data, but if the SAM file became corrupted I think it would be a good idea to run a chkdsk on the drive, if you don't check the drive this problem may rear its ugly head down the road again.

Guest Tractor Posted July 30, 2008 Posted July 30, 2008 Re: Logon Problem Thank you very much. I am back in the computer. Changing the SAM folder did the trick. Thanks again.

Guest Neil Posted August 5, 2008 Posted August 5, 2008 Re: Logon Problem Hi Guys, I am having the same problem on a friends laptop, however starting in safe mode, or safe mode with command prompt still takes me to the welcome screen with no user accounts. I can ctrl-alt-del but they dont know their password as it always auto logged in. I have put the windows xp cd in and when I attempted a system recovery it asked for a administrator password which I dont have (i tried blank, "password", "admin" etc to no avail). Everything I try to do still takes me to the welcome screen. Is there anyway to get to a command prompt?
