It should work with Windows Server 2003 (not with 2K) and Windows XP
clients **with SP3**.

The problem we were seeing is, that IIS (or better the certificate viewer - MMC certificate snap-in) complains about invalid signature or certificate corrupted (even though it apparently showed the details correctly :S).

Searching through forums and postings I've found fairly recent stuff like:

"Windows XP/2003 cannot consume certificates using SHA2 algorithms
(SHA256, SHA512, SHA384)."


It really surprising that you should have problem with Windows Server
2003. Whilst I didn't spend too much time investigating SHA-2 with IIS,
I know some other software that successfully use it on W2K3.

A solution would be extremely appreciated. Can anybody with good knowledge on this platform advise?

Firefox knows about SHA-2 since Firefox 2.

Legacy software will certainly fail, like Firefox 1.5 and IE6 (maybe also IE7 on XP). I know those should be discouraged from being used, but can we risk it for them to fail? I think IE6 still has some followers, no (~20%)?
