Can't get one of my solutions to work on a Windows Server 2003 based server. Client works fine, but server side X509-based decryption fails with an error that should not happen (Cannot find the certificate and private key for decrtyption).
Everything installed and correctly setup. Even permissions. :)
Since even the official Microsoft newsgroup didn't help, I'm really stuck. The funny thing is, that if I disallow access to private key and/or remove the certificate, error message changes giving me a clue that WSE looks at the cert unsuccessfully.
