This problem occurs because of a regression error in security update 917422 (MS06-051) for Windows 2000 Service Pack 4. This regression error causes the GetWindowsDirectory System Information function not to return the correct directory information to certain programs. These programs are ones that are not Terminal Services aware and that are running in a Terminal Services environment.
For example, the GetWindowsDirectory System Information function may return "C:\Winnt" when it should return "C:\Documents and Settings\username\Windows."
