MSMQ Err: Error While Creating MSMQ Internal Certificate. Error: 0x8000ffff

This article has been archived. It is offered "as is" and will no longer be updated.
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.
