SMB “Access is denied” Caused by Anti-NTLM Relay Protection
SummaryObservationHow to troubleshoot?How to Configure The Policy?How Does This Protection Work?Offensive Security PerspectiveWhat Do We recommend?We investigated a situation where an SMB client could not connect to an SMB server. The SMB server returned an “Access Denied” during the NTLM authentication, even though the credentials were correct and there were no restrictions on both the server-side share and client-side (notably UNC Hardened Access). The only unusual thing is that the SMB ser...See more on medium
