Objective: I need to run this executable program on this path "\\172.168.0.46\Inhouse Module\Michael Panaligan\AllUnit\RunCom.exe"
It's working on my local computer but not on IIS Server Side. I don't know why it's not working on IIS Server Side when it's completely fine on my local unit.
Thank you!

Here's my script.

VB.NET

Imports System.Diagnostics

Public Class CallLegacyApp
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim networkPath As String = _
   "\\172.168.0.46\Inhouse Module\Michael Panaligan\AllUnit" ' Rename folder without spaces
        Dim executablePath As String = "RunCom.exe"

        Try
            ' Map network drive using net use command
            Dim netUseStartInfo As New ProcessStartInfo("net.exe", _
            "use " & networkPath & " /USER:nkti\sdg programmers")
            Process.Start(netUseStartInfo).WaitForExit()

            ' Start the program
            Dim startInfo As New ProcessStartInfo()
            startInfo.FileName = networkPath & "\" & executablePath
            Process.Start(startInfo)
        Catch ex As Exception
            Response.Write("Error: " & ex.Message & "<br>" & ex.StackTrace)
        End Try

    End Sub

What I have tried:

Tried to understand Shell and Process.Start function. Did some research and ask AI.

I received this error:

First issue: You've not provided a password in your net use command, only a username.

Second issue: You're launching the application using the UNC path, so the net use command is irrelevant.

Third issue: you haven't explained what the problem is. At a guess, you're expecting the application to launch on the client, which will never work when you launch it from code running on the server. It might appear to work when you debug it locally, but that's just because, in that specific case, the client and server are the same machine.

Sir,
about the first issue you mentioned the password is programmers
Here: Dim netUseStartInfo As New ProcessStartInfo("net.exe", "use " & networkPath & " /USER:nkti\sdg programmers")

Second Issue: Thank you sir, I will take note of this.

Third issue:
You're right sir, I'm expecting to launch the application on the client.
All files are existing on the client computer.

The problem, when I try to run the webpage on the server I received error like this.
Error: The system cannot find the file specified
at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo) at System.Diagnostics.Process.Start(ProcessStartInfo startInfo) at LegacyApp.CallLegacyApp.Page_Load(Object sender, EventArgs e) in D:\ROS MOD BKP Sept 9 2016\CALL_LEGACY_APP\LegacyApp\LegacyApp\CallLegacyApp.aspx.vb:line 18

Is there a way to lunch the application to client sir?

No, not from a web app. What you are describing is a massive security risk and is not allowed by browsers.

wmic /node:172.168.0.46 process call create "full path to exe and parameters"

You may need to do some additional research around authenticating to the target. Based on my (brief) testing, the result process is running at a system level, not a user level.

This will do nothing for the OP. He's trying to launch an executable on a client machine from code running on a web server. That is never going to work.

my apologies. it wasn't clear to me that the OP was asking about a web server and client

Well, there's you problem.

Code running on the server cannot launch an application on the client.

It might appear to work when you debug your code locally. But that's only because, in that specific situation, the client and server are the same machine.

As soon as you try to run your code on a real server, one of two things will happen. In the best case, your code will crash indicating that you can't launch an interactive application on the server. In the worst cast, it will launch the application on the server, where nobody will ever see it, and then hang waiting for someone to log in to the server and close the application.

And no, before you ask, you won't be able to launch the application from JavaScript running on the client either.

And linking to a UNC path from a web site won't work; most modern browsers will explicitly block such links.

The best you can do is to transmit the exe file in the Response with appropriate headers (content-type application/octet-stream, and possibly a content-disposition as well). The user should then be given the choice to save, run, or discard the file. (And no, you can't force them to pick the "correct" option here.)

But doing that from your Page_Load event handler is generally not a good idea. You can't return any other content along with the file download, so the rest of your page code will be irrelevant.
