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