Microsoft added support for ECC (Elliptic Curve Cryptography) starting with Windows Server 2008. While the support is present in Server 2008 - Server 2012 R2, the default CSP (Cryptographic Service Provider) is set to generate RSA keys. In order to generate an ECC key, the CSP must be manually specified. This can be accomplished with a CSR request through the MMC.
