CAUSE

This problem occurs because the Visual Studio 6.0 SP6 Setup program removes the Everyone group from the list of authorized users and groups for the Mfc42.dll file.

Microsoft Internet Information Services (IIS) uses the IWAM_ComputerName user account to start out-of-process applications. However, because the Visual Studio Setup program has removed the Everyone group from the list of authorized users and groups for the Mfc42.dll file, the IWAM_ComputerName user account no longer has the Read & Execute permission for the Mfc42.dll file.

Note ComputerName is a placeholder for the name of your computer.

RESOLUTION

To resolve this problem, grant the IWAM_ComputerName user account the Read & Execute permission for the Mfc42.dll file. The Mfc42.dll file is located in the %WINDIR%\System32 folder.

To grant the Read & Execute permission, follow these steps:
  1. In Windows Explorer, locate the Mfc42.dll file.
  2. Right-click the Mfc42.dll file, and then click Properties. The Properties dialog box appears.
  3. Click the Security tab, and then click Add. The Select Users or Groups dialog box appears.
  4. In the Name field, locate and then click IWAM_ComputerName.
  5. Click Add, and then click OK.
  6. Make sure that the Allow check box is selected for the Read & Execute permission, and then click OK.

STATUS

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