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.
