TITLE   :MSMQ Err: Error While Creating MSMQ Internal Certificate
PRODUCT :Microsoft Message Queue Server
PROD/VER:1.0
OPER/SYS:WINDOWS NT
KEYWORD :kbbug4.00 kbfix4.00 

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

 - Microsoft Message Queue Server version 1.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you click Renew Internal Certificate in the Microsoft Message Queue Control
Panel tool on February 29 of a leap year (for example, the year 2000, 2004,
2008, and so on), the following error message is displayed:

   Error while creating MSMQ internal certificate. Error: 0x8000ffff

CAUSE
=====

The Microsoft Message Queue (MSMQ) program submits a request to set the
expiration date of the newly created certificate to 10 years; however, MSMQ does
not take into account leap years when it determines the expiration date. For
example, if you create a certificate on February 29, 2004, MSMQ attempts to set
the expiration date to February 29, 2014. This is an invalid date because it is
not a leap year.

RESOLUTION
==========

Mqrt.dll has been modified to request a validity of eight years rather than 10.
