Guenther and I found actual issue -- rpc_create_tcpip_sockets() passed empty string (non-NULL, '') to dcerpc_binding_vector_add_port() and then dcerpc_binding_vector_add_port() tried to set binding's option 'host' to this string. With the commit 017338a1 which is also 4.2 only, setting empty string to special properties of the binding is not possible: + if (value[0] == '\0') { + return NT_STATUS_INVALID_PARAMETER_MIX; + } + Following patch fixed the issue for us: commit 1ff9ffea061e4bdecea65749d8d0e3c082e25d77 Author: Günther Deschner <gd> AuthorDate: Thu Apr 30 11:20:58 2015 +0200 Commit: Günther Deschner <gd> CommitDate: Thu Apr 30 11:22:26 2015 +0200 s3-rpc_server: fix rpc_create_tcpip_sockets() processing of interfaces. We were supplying an empty value for the "host" binding string option, causing dcerpc_binding_vector_add_port() call to fail.
