I am trying to create a self-signed certificate in IIS 7 on Windows Server 2008, but I get the error, 'The parameter is incorrect'. I can't find any other information about this error, does anyone know what the problem is, or where I can look to to find more information about what is going wrong?

I experienced the same issue this morning, this is caused by this year being a leap year and today the 29th of February. Set your system time back to yesterday and you will be able to create the cert.

    Microsoft is aware of this issue but as of 2016 it still exists: *"Thanks for reporting the bug. This issue pertains to creation of SSL certificates by the System Center 2012 VMM server for a variety of tasks such as installation, adding a host, adding a library and deploying services. We understand the issue and are investigating further. This issue is related to the leap year date of 2/29 and will not impact operations hereafter."* - DeWitt Hurst [MSFT]Microsoft (MSFT) /via https://goo.gl/GmfveQ – John K Mar 01 '16 at 13:57
