I have tried to install server certificate SHA256 + RSA 2048 in IIS 6.0 + Windows Server 2003 (SP2) but I was not successfull. I also installed the hotfix 968730 but it did not help. If I make a request of certificate from IIS, the request is made with SHA1 certificate (instead of SHA256 as I need). If I try to import an SHA256 certificate (pfx file) using IIS everything goes smooth but when I try to connect to the HTTPS web site the client does not reach it. Is it possible to install this type of certificates with IIS 6.0 and Windows Server 2003 or IIS 7.0 + Windows Server 2008 is needed. Thanks and ciao

You need Windows Server 2008 to use the SHA256 in IIS.
