Tohle by mělo pomoci:The problem was that website I was connecting to was only configured to accept RC4 ciphers, for example, TLS_RSA_WITH_RC4_128_SHA.Internet Explorer was not advertising any RC4 ciphers, no matter how I configured it. I suspected that it had to do with the FIPS Compliant Algorithms group policy, but the policy was disabled. Microsoft's documentation states that the GPO controls the reg key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy]. This key was disabled, I had checked it multiple times. After exhausting all my options, I decided to just search the entire registry for "FIPS" and track down each reference. Low and behold, there was a value under the key [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa] called "fipsalgorithmpolicy", and it was set to 1. After setting it back to 0 an rebooting, IE started advertising the RC4 algorithm properly..A tady je k tomu diskuse: http://community.spiceworks.com/topic/401868-schannel-fat...
