SYMPTOMS

When you upgrade or install Microsoft Windows XP, passwords may be assigned to user accounts that previously had no password or you did not assign passwords to any user accounts during the installation process. As a result, you cannot log on to the computer.

CAUSE

This behavior occurs if Windows XP Setup does not complete properly. Setup assigns temporary passwords to user accounts during the upgrade process, and is supposed to remove the passwords when Setup is complete. The temporary passwords are written to the Setupact.log file that is located in the folder in which Windows is installed.

RESOLUTION

To resolve this behavior, retrieve the password from the Setupact.log file, and then use the password to log on to the computer. You must search the Setupact.log file for the following line, where Username is the name of the user account and xxxxxxxxxxxxx is the password for that account:

Random password for Username is xxxxxxxxxxxxx

To do this, use one of the following methods, as appropriate to your situation.

Windows XP Is Installed on a FAT32 Partition

To retrieve the password from the Setupact.log file if Windows XP is installed on a FAT32 partition, follow these steps:

Insert a Microsoft Windows Millennium Edition (Me) startup disk or a Microsoft Windows 98 Startup disk into the computer's floppy disk drive, and then restart the computer.

edit drive:\windows\setupact.log
Locate the following line, where Username is the name of the user account and xxxxxxxxxxxxx is the password for that account:

Random password for Username is xxxxxxxxxxxxx
Make a note of the password exactly as it appears in the Setupact.log file, and then quit the text editor.
Restart the computer, and then log on to the computer with the user account by using the password that you retrieved.

After you are logged on to the computer, reset the password for the user account by using User Accounts in Control Panel.

Windows XP Is Installed on a NTFS Partition

To retrieve the password from the Setupact.log file if Windows XP is installed on an NTFS partition, follow these steps:

Configure the computer to start from the CD-ROM drive or DVD-ROM drive. For more information about how to do this, please see the computer's documentation or contact the computer manufacturer.

When the Welcome to Setup screen is displayed, press the R key to start the Recovery Console.
Select the installation that you need to access from the Recovery Console.
You are prompted for the Administrator password. If the Administrator password is set to use a blank password, just press ENTER.
At the command prompt, type the following line and then press ENTER:

type setupact.log
Locate the following line, where Username is the name of the user account and xxxxxxxxxxxxx is the password for that account:

Random password for Username is xxxxxxxxxxxxx
Make a note of the password exactly as it appears in the Setupact.log file.
Type exit at the command prompt, and then press ENTER to quit the Recovery Console and restart the computer.
