Copy and paste from server to remote PC in network

Hello to all. I was wondering if someone could point me in the right direction to solving a problem I'm having in VB.NET. I am attempting to make an app that will copy a file (most times an icon) from our server and pasting it onto a remote users PC on the network. I work in the IT department in the service desk and I would say that at least 30% of my calls are people that have for some reason or other have lost an icon they need. I created a main form, and put a text box and coresponding button. I would like it so that I would only have to input their computer number (example wxp*****)
and press the button to send the file. My code thus far is:

 Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComputerNumber.TextChanged

        Dim PCNumber As String
        PCNumber = Me.ComputerNumber.Text

    End Sub

    Private Sub Button7_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button7.Click

        Dim PCNumber As String
        PCNumber = Me.ComputerNumber.Text

        My.Computer.FileSystem.CopyFile("\\intranet1\sd\SDReferenceTool\Files\Shortcuts - Popular\SCM Shortcuts\SCM 5.5 PROD.ICA", "\\PCNumber\C$\Documents and Settings\All Users\Desktop\SCM 5.5 PROD.ICA")

    End Sub

When trying to debug, I get the following error. IOException was unhandled. The network path was not found. However, the app will launch but is doesn't work.

I double-checked the server address and it is correct. The only thing I can think of is that I screwed up the textbox somehow so it is not entering in the PC number like I had intended. I have admin rights on my workstation and can share remotely using the path in the run command. Any pointers is as always appreciated.
