The /E option for Winnt32.exe can be used to start Update.exe to install Windows NT 4.0 Service Pack 4 (SP4) following the installation of Windows NT. This method of installing Windows NT and applying SP4 is typically used by original equipment manufacturers (OEMs). Windows NT may stop responding (hang) towards the end of the Service Pack 4 installation when you use this switch.


This problem occurs when SP4 Setup attempts to load Nwlnkipx.sys if the Nwlnkipx.sys version that is available with Windows NT 4.0 is already loaded.


To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
  • Windows Service Pack Center -or-

  • 152734 how to obtain the latest windows nt 4.0 service pack
For information on obtaining the individual software update, contact Microsoft Product Support Services. For a complete list of Microsoft Product Support Services phone numbers and information on support costs, please go to the following address on the World Wide Web:


Microsoft has confirmed that this is a problem in Windows NT 4.0 SP4. This problem was first corrected in Windows NT version 4.0 Service Pack 5.
