CAUSE
This behavior occurs when you access the wizard through the manage user permissions option of the Manage Users page of the SBS console, or when you attempt to modify user permissions through the Add User Wizard (the Addusrw.exe file), which you start from the add a user option of the Manage Users page.
RESOLUTION
The wizard does not complete because of the incompatible versions of the files Mfc42.dll and Mfc42u.dll present in the %Windir%\System32 directory. To resolve this behavior, use one of the following methods:

Method 1: Selectively Replace Files

NOTE: This method is preferred when third-party applications are installed.
  1. Insert SBS 4.5 CD-ROM 2 in the CD-ROM drive.
  2. Open a command prompt and type the following command:
    cd \smallbusiness
  3. Press ENTER.
  4. At the same command prompt, type the following command:
    extract CD-ROM:\ntoptpak\en\x86\winnt.srv\msmqocm.cab mfc42*.dll
    where CD-ROM is the drive letter of your CD-ROM drive.
  5. Press ENTER. You have extracted the two files to the \Smallbusiness folder.
  6. Close the console and reopen it to run the wizard. In some cases, you may have to restart your computer.

Method 2: Overwrite Existing System Files

  1. Rename %Windir%\System32\Mfc42.dll to %Windir%\System32\Mfc42.old.
  2. Rename %Windir%\System32\Mfc42u.dll to %Windir%\System32\Mfc42u.old.
  3. Insert SBS 4.5 CD-ROM 2 in the CD-ROM drive.
  4. At a command prompt, find %Windir%\System32 by typing (in most cases):
    cd \winnt.sbs\system32
  5. At a command prompt, type the following command:
    extract CD-ROM:\ntoptpak\en\x86\winnt.srv\msmqocm.cab mfc42*.dll
    where CD-ROM is the driver letter of your CD-ROM drive.

    Press ENTER.Restart the SBS computer.NOTE: Replacing these files in the %Windir%\System32 folder may cause problems with third-party programs that require the updated versions.
