Please refer to the URL: http://www.microsoft.com/technet/security/bulletin/MS09-007.mspx My application is using Java to establish connections with an IIS server on a Windows Server 2003. The patch above is installed on the W2k3 server. After the installation of the patch, the SSL connection between my Java client and the IIS server cannot be established. More specifically, it fails during SSL handshaking. I'd like to find out what are the additional requirements due to this patch i.e. does it require additional SSL messages "CertificateVerify"? If a Java client is working fine previously, what are the extra SSL messages required due to this hotfix? 1 person needs an answerI do too
