I have a SBS2008 server running exchange and OWA. My client is very happy with it and makes a lot of use of OWA.

However he also needs PCI Scans to check whether his network is secure from his credit card processing company. This is a requirement and is essentially a fancy port scan. Unfortunately port 443 and OWA fails the security test. This is because OWA accepts SSLv2 connections, in order to pass the test I must restrict the server to only accept SSLv3 connections.

Anyone already dealt with this, these security scans are pretty commonplace.

Sorry I should have added more info. I have already found the KB article

http://support.microsoft.com/kb/187498

Which talks about it but the settings do not seem to relate to my SBS2008 install. It talks about keys in

HKey_Local_Machine\System\CurrentControlSet\Control\SecurityProviders \SCHANNEL\Protocols

My server has only one key in there for SSL 2.0. However this is for the client only and the article talks about changing the server entry in the registry.

I think I am in the right area but dont fancy randomly changing regisitry settings that 'look right' on a production server :)
