Description:

CAUSE : User names and passwords for the IUSR_ComputerName and IWAM_ComputerName accounts are stored in three locations:

  • Internet Information Server (IIS) metabase
  • User Manager for Domains (Windows NT) or Local Users and Groups
  • Microsoft Transaction Server (Windows NT) or Component Services

If the user names and/or passwords are not synchronized among these three locations, the above error occurs.

Solution:

To resolve this problem, you must make sure that the passwords for the IUSR and IWAM accounts are synchronized in locations mentioned above. There are two ways to achieve this: you can set the password for IWAM and IUSR accounts in User Manager (Windows NT) or Users and Groups and change the passwords in IIS metabase to reflect the same password, or vice versa.

Method 1: Change the Passwords in User Manager or Users and Groups to Match the IIS Metabase Password

  1. In the Command window, locate the folder that contains the Adsutil.vbs file. Use the Adsutil.vbs tool to obtain the passwords for the IWAM and IUSR accounts from the IIS metabase.

  2. To change the IUSR and/or IWAM passwords in Windows NT, follow these steps:

    1. From the Start menu, go to Programs-> Administrative Tools and double-click User Manager for Domains. In User Manager for Domains, you can change the account information for all Windows NT user accounts and groups.

    2. Double-click the IUSR_ ComputerName and/or IWAM_ ComputerName users, and modify the passwords so that they reflect the IIS metabase password that you obtained in step 1.

      To change the IUSR and/or IWAM passwords in Windows 2000/2003, follow these steps:

      1. From the Start menu, go to Programs-> Administrative Tools and double-click Computer Management.

      2. Under the System Tools node, click to expand the Local Users and Groups and Users nodes. In the User node, you can change the account information for all Windows 2000/2003 user accounts and groups.

      3. Right-click the IUSR_ ComputerName and/or IWAM_ ComputerName accounts, and then click Set Password.

      4. Modify the passwords so that they reflect the IIS metabase password that you obtained in step 1.

      5. Browse to the ASP page that returned the error message to check if the problem still persists.

Method 2: Change the IIS Metabase to Match the IUSR and/or IWAM Passwords

  1. To change the IUSR and/or IWAM password in Windows NT, follow these steps:

    1. From the Start menu, go to Programs-> Administrative Tools and double-click User Manager for Domains. In User Manager for Domains, you can change the account information for all Windows NT user accounts and groups.

    2. Double-click the IUSR_ ComputerName and/or IWAM_ ComputerName accounts, and type new passwords.

      To change the IUSR and/or IWAM password in Windows 2000/2003, follow these steps:

      1. From the Start menu, go to Programs-> Administrative Tools and double-click Computer Management.

      2. Under the System Tools node, click to expand the Local Users and Groups and Users nodes. In the User node, you can change the account information for all Windows 2000/2003 user accounts and groups.

      3. Right-click the IUSR_ ComputerName and/or IWAM_ ComputerName accounts, and then click Set Password. Type new passwords.

  2. In the Command window, locate the folder that contains the Adsutil.vbs file. Use the Adsutil.vbs utility to set the passwords for the IWAM and IUSR accounts in the IIS metabase.

  3. Browse to the ASP page that returned the error message to check if the problem has been resolved.
