[Kerberos/NTLMv2/v1]: Select this to use the function in an environment both the Active Directory domain and NT domain exist. Click Send LM & NTLM - use NTLMv2 session security if negotiated. About the hash. In addition to NTLM v1, an MD4 hashed 8-byte client challenge is appended to the 8-byte server challenge. For basic authentication, this is the md4 of the NTLM hash, concatenated with the response hash; for extended authentication, this is just the md4 of the NTLM hash. It is generated on the computer that was accessed. hash Did you know that your Windows computers store and send weak password hashes which are very easy to crack? Even if you run legacy operating systems, there are methods that you can implement that will protect against these weak authentication protocols and password hashes being generated. You are currently viewing LQ as a guest. net framework, cloud, windows azure, windows store apps, workflow manager, service bus The NTLM authentication protocol doesn't include any way to "negotiate" the authentication method (NTLM vs NTLM v2); Windows boxes need to be manually configured by changing a registry setting to specify what kind of responses they send and what kind of responses the server will accept.
