TITLE   :APIs Do Incorrect Comparisons
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:BUGLIST3.10 FIXLIST3.10.001

----------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT operating system version 3.1
 - Microsoft Windows NT Advanced Server version 3.1
----------------------------------------------------------------------


SYMPTOMS
========

APIs do incorrect comparisons when two port APIs take a parameter as
an integer then do comparisons of the integer against an unsigned
short that is incorrectly sign-extended. If a port or protocol number
greater than 127 is passed into these routines, they will not return
any information.

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT and Windows NT
Advanced Server version 3.1. This problem was corrected in the latest U.S.
Service Pack for Windows NT and Windows NT Advanced Server version 3.1. For
