Appendix C. Windows NT Server 4.0 Service Packs
It is advisable to install the latest service pack available from Microsoft, as this
will contain the most recent bug fixes for the product.
Service packs for NT 4.0 are available from Microsoft on CD-ROM, or they can be
downloaded from the Internet at the following URL:
ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/nt40
At the time of publication, service pack 2 was available for download from this
FTP site. Service packs are cumulative, that is, they contain the fixes of all
previous service packs. Therefore, if you are installing service pack 2, you do
not have to install service pack 1 first.
The README file associated with each service pack list what fixes are included.
The updated symbols for the service packs are also available at the FTP site.
Note: Ensure you obtain the symbols and service packs for the Intel platform.
The FTP site contains code for MIPS, Alpha and PowerPC hardware as well.

All encryption related components in the version of service pack 2 are limited to

containing 128-bit encryption, is about to be replaced by an updated component
with 40-bit encryption. If you require 128-bit support, you should click the Cancel
button on the dialog box.
A version of this service pack with 128-bit encryption is also available on request
