使用 JCIFS 与远程 Windows 实例通信时出现 nca_proto_error/DERPC_FAULT_PROTO_ERROR

我目前正在尝试做一些类似于 PSExec 但完全用 Java 的事情。我认为我的问题与我实际正在做的事情并不直接相关，而是与如何做有关。目前我正在尝试远程实现服务的创建和启动。

为此，我使用了 midlc 工具（版本 0.6.1），并通过 CreateService 和 DeleteService 调用扩展了 svcctl.idl。之后，我使用 midlc 生成与 jcifs ( -t jcifs ) 一起使用的代码。然后，我创建了一个测试程序来使用该类和 jcifs 与远程 Windows 计算机进行通信。

这是代码：

        rpc.policy_handle scHandle = new rpc.policy_handle();
        SvcCtl.OpenSCManager openSCManagerRpc = new SvcCtl.OpenSCManager(host, null, 0x0001 | 0x0002, scHandle);

        // Connection-oriented DCE/RPC over SMB named pipes.
        DcerpcHandle handle = DcerpcHandle.getHandle("ncacn_np:" + host + "[\\PIPE\\svcctl]",
                ConcurrentNtlmAuthenticator.getInstance().getNtlmPasswordAuthentication());
        try {
            handle.sendrecv(openSCManagerRpc);
            if (openSCManagerRpc.retval != 0) {
                throw new SmbException(openSCManagerRpc.retval, true);
            }
        } catch(Exception e) {
            e.printStackTrace();
        } finally {
            try {
                handle.close();
            } catch(IOException ioe) {
                ioe.printStackTrace();
            }
        }

不幸的是，我收到 DCERPC_FAULT_PROTO_ERROR 别名 nca_proto_error 别名 0x1c01000b

所以我的简单问题是......我做错了什么？

I am currently trying to do something similar to PSExec but entirely in Java.
I think my problem isnt directly relate to actually what I am doing, but how.
Currently I am trying to implement the creating and starting of a service remotely.

For this I got my hands on the midlc tool (version 0.6.1) and extended the svcctl.idl with the CreateService and DeleteService calls. After that I used midlc to generate code for usage with jcifs ( -t jcifs ). I then created a test-program to use that class and jcifs to communicate with a remote windows machine.

Here comes the code for that:

        rpc.policy_handle scHandle = new rpc.policy_handle();
        SvcCtl.OpenSCManager openSCManagerRpc = new SvcCtl.OpenSCManager(host, null, 0x0001 | 0x0002, scHandle);

        // Connection-oriented DCE/RPC over SMB named pipes.
        DcerpcHandle handle = DcerpcHandle.getHandle("ncacn_np:" + host + "[\\PIPE\\svcctl]",
                ConcurrentNtlmAuthenticator.getInstance().getNtlmPasswordAuthentication());
        try {
            handle.sendrecv(openSCManagerRpc);
            if (openSCManagerRpc.retval != 0) {
                throw new SmbException(openSCManagerRpc.retval, true);
            }
        } catch(Exception e) {
            e.printStackTrace();
        } finally {
            try {
                handle.close();
            } catch(IOException ioe) {
                ioe.printStackTrace();
            }
        }

Unfortunately I am getting a DCERPC_FAULT_PROTO_ERROR alias nca_proto_error alias 0x1c01000b

So my simple question is ... what am I doing wrong?
