How to execute a command in a remote computer?

Question

I have a shared folder in a server and I need to remotely execute a command on some files. How do I do that?

What services need to be running on the server to make that work?

Some details: Only C# can be used. Nothing can be installed in the server.

Another solution is to use WMI.NET or Windows Management Instrumentation.

Using the .NET Framework namespace System.Management, you can automate administrative tasks using Windows Management Instrumentation (WMI).

Code Sample

using System.Management; ... var processToRun = new[] { "notepad.exe" }; var connection = new ConnectionOptions(); connection.Username = "username"; connection.Password = "password"; var wmiScope = new ManagementScope(String.Format("\\\\{0}\\root\\cimv2", REMOTE_COMPUTER_NAME), connection); var wmiProcess = new ManagementClass(wmiScope, new ManagementPath("Win32_Process"), new ObjectGetOptions()); wmiProcess.InvokeMethod("Create", processToRun); 

If you have trouble with authentication, then check the DCOM configuration.

1. On the target machine, run dcomcnfg from the command prompt.
2. Expand Component Services\Computers\My Computer\DCOM Config
3. Find Windows Management Instruction, identified with GUID 8BC3F05E-D86B-11D0-A075-00C04FB68820 (you can see this in the details view).
4. Edit the properties and then add the username you are trying to login with under the permissions tab.
5. You may need to reboot the service or the entire machine.

NOTE: All paths used for the remote process need to be local to the target machine.

You could use SysInternal's PsExec.
