 The **NetSetup.log** file shows that the client can't establish an SMB session with the DC. In the network trace, the SMB SESSION SETUP response has an error `NT Status: System – Error. Code  = (187) STATUS_NOT_SUPPORTED`. It indicates that the DC returns `STATUS_NOT_SUPPORTED` to the C SESSION SETUP request from the client. The DC rejects the client's credentials in the C SESSION SETUP request, which is the initial step of NT LAN Manager (NTLM) authentication.
