SYMPTOMS
========

When you attempt to install a printer in Windows NT 3.51, the following error
message appears:

  The application or dll ./devices/<drive>:/<%SystemRoot%>/system32
  /spool/drivers/w32x86/rasddui.dll is not a valid Windows NT image. Please
  check this against your installation diskette.

CAUSE
=====

This problem occurs when Print Manager is not able to load RASDDUI.DLL due to
heavy I/O stress of the computer. The RASDDUI.DLL is unloaded if Windows NT has
been using it before installing the printer. This problem may occur with files
other than RASDDUI.DLL.


STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.51. This
problem was corrected in the latest US Service Pack for Windows NT. For

To correct this problem, upgrade to Windows NT 3.51 Service Pack 2.
