Agree...this is unacceptable from Intuit's part.  After paying 4k+ a year, all we get is that it might be our computers.  They need to admit that they are taking the support out of Windows Server 2012.  They just updated the requirements for enterprise and Windows Server 2012 is not a supported version.

At least they could have said something before forcing us and blocking our business from processing payments and anything web related.
