I am trying to find out the remote system information over LAN by using the ip address of that system. But i am not able to getting the information. i am using the following code but i am getting the error.

C#

try
            {
                ObjectQuery queryObj = new ObjectQuery("SELECT * FROM Msvm_ComputerSystem");
                ConnectionOptions connOpts = new ConnectionOptions();
                connOpts.Username = "********";
                connOpts.Authority = "ntlmdomain:" + "*******";
                connOpts.Password = "*********";
                ManagementScope manScope = new ManagementScope(@"\\RemoteSystem\root\virtualization", connOpts);

                // connect and set up our search
                ManagementObjectSearcher vmSearcher = new ManagementObjectSearcher(manScope, queryObj);
                ManagementObjectCollection vmCollection = vmSearcher.Get();
                foreach (ManagementObject vm in vmCollection)
                {
                    MessageBox.Show(vm["ElementName"].ToString());
                    
                }


            }

I am getting the following error

Well, and did you set up an RPC (Remote Procedure Call) on the remote system?
--SA

Please see my comment to the question. Remote system information cannot be obtained without collaboration with some software on the other side. In this case, you are supposed to run the RPC (Remote Procedure Call) server on the remote machine, please see:
http://en.wikipedia.org/wiki/Remote_procedure_call[^].

Please see this article covering many issues related to RPC: http://social.technet.microsoft.com/wiki/contents/articles/4494.troubleshooting-the-rpc-server-is-unavailable.aspx[^].
