Hi, we had to reduce the ciphers on our servers to the really limited set of KRB5-RC4-MD5 KRB5-RC4-SHA ADH-RC4-MD5 RC4-SHA to work around this really annoying windows update.

If possible try to reproduce with the s_server utility. I've an idea what this might be. Try disabling RSA key exchange ciphersuites on the server too (adding :!kRSA to SSLCipherSuite) and see if that resolves the problem. Steve. -- Dr Stephen N. Henson. OpenSSL project core developer.
