SYMPTOMS

When you run a Terminal Services administrative utility, such as Tsprof.exe, Mmc.exe, or Usrmgr.exe, the utility may generate an access violation error and quit unexpectedly when it manages certain user accounts.

When you run any program that uses the API functions of WTSSetUserConfig or WTSQueryUserConfig to set or to retrieve user information, the utility may generate an access violation error and quit unexpectedly when it manages certain user accounts.

When you make a Remote Desktop connection and then try to log on with a certain user account, the Remote Desktop connection may suddenly close. If the Remote Desktop-based logon attempt was to a Microsoft Windows XP-based computer or to a Microsoft Windows Server 2003-based console computer, the Remote Desktop computer will perform a bugcheck after Winlogon unexpectedly quits. Depending on the configuration, the Remote Desktop computer may restart.

One or more of the following events may be written to the event log:

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

Windows XP

This problem was first corrected in Microsoft Windows XP Service Pack 2.

MORE INFORMATION

The hotfix that is described in this article does not correct the corrupted data. The hotfix protects the code from causing the process to quit unexpectedly with an access violation error.

After you apply this hotfix, you may be able to log on to a Windows 2000-based or a Windows XP-based computer by using Remote Desktop without errors. However, you may still receive an error message when you change the properties of the user account or when you log on by using that account.

If you use Microsoft Management Console (MMC) to edit or view the user properties, you may receive an error message that is similar to the following:
Terminal Services Properties
Could not load Terminal Services properties for this user because: The parameter is incorrect.
Or, When you try to log on to a Windows Server 2003-based computer by using a Remote Desktop connection, you may receive an error message that is similar to the following:
Logon Message
The system could not log you on due to the following error: The parameter is incorrect.
Please try again or consult your system administrator
To correct the Terminal Services user data corruption, follow these steps:
  1. Create a text file with the following lines of text, where username is the name of the user account with the corrupted information and where domain is your domain name.
    dn: CN=username,CN=Users,DC=domain,DC=com
    changetype: modify
    delete: userParameters
  2. Name the file "Users.txt."
  3. At a command prompt, type the following command to run the file:
    Ldifde –I –f users.txt
    Running this command will also clear the properties and resolve the issue on an Active Directory domain.

    Note Clearing the userParameters attribute in the user account may affect other programs. If program-specific information is stored there, it will have to be repopulated. For example, programs that may be affected are FPNW, RAS, and all Terminal Services-specific user information.
