SYMPTOMS
========

If you applied a Windows NT 4.0 service pack from a network share, you may not
be able to uninstall the service pack.

CAUSE
=====

This may occur if loss of network connectivity has made Update.exe or the
service pack executable (that is, nt4sp3_i.exe) inaccessible because it resides
on another server.

RESOLUTION
==========

NOTE: In order to uninstall the Windows NT service pack, the option to create an
uninstall directory must have been chosen during the application of the service
pack and the %SystemRoot%\$NTServicePackUninstall$ must exist.

If the service pack was installed from the self-installing file (for example, the
Service Pack 3 executable file is called nt4sp3_i.exe), perform the following
steps:

1. From the system that contains the nt4sp3_i.exe executable file, extract the
  files to a directory by typing the following from an MS-DOS command prompt:

  nt4sp3_i.exe /x

  This will expand all the Service pack files without installing them.

2. Copy the files Update.exe, License.txt, and Update.inf to a floppy disk.

3. Run Update.exe from the floppy disk on the Windows NT system you want to
  uninstall the service pack from, and you will be prompted with the option to
  uninstall the service pack.

If the service pack was installed from a previously extracted service pack
directory on another server, perform the following steps:

1. Copy the files Update.exe, License.txt, and Update.inf to a floppy disk.

2. Run Update.exe from the floppy disk on the Windows NT system you want to
  uninstall the service pack from, and you will be prompted with the option to
  uninstall the service pack.
