I have a DNN 4 module that works on my local machine.  This module has been loaded on a DNN 4 installation on another server.  It works fine on that server.

I have added many more functions and code to this module and successfully uploaded the module to the DNN4 installation on the other server.

I have added new code that does not work!  I am trying to upload/copy an "xml" file from any of my drives to the /portals folder.  It works fine on my localhost.  But when I run it from the remote server I getting the following error message:

A critical error has occurred. Could not find a part of the path 'C:\DNNAssessment\Website\DesktopModules\MIMH.DNNAssessment\eHealthLiteracyScale.xml'.

Basically I am using the <input id="cmdBrowse" ...> to upload this file

I am including part of the settings.ascx user control where this code is found:

<tr>
    <td class="SubHead" width="150">
        <dnn:Label ID="lblUploadAssessment" runat="server" ControlName="AddNewAssessment" Text="Add: " />
    </td>
    <td valign="bottom" width="480">
         <input id="cmdBrowse" type="file" size="40" name="cmdBrowse" runat="server">&nbsp;&nbsp;
         <asp:LinkButton ID="cmdUpload" resourcekey="cmdAdd" runat="server" CssClass="CommandButton" class="CommandButton" Text="Add" BorderStyle="none" />
    </td>
</tr>

the code the works on the localhost but fails on the remote server.  This code is taken from my cmdUpLoad_Click() from settings.ascx.vb:

Protected Sub cmdUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdUpload.Click

If Page.IsPostBack Then
    Dim strFile As String = cmdBrowse.PostedFile.FileName

    If strFile <> "" Then
        Dim assessmentController As New MIMHAssessmentController
        Dim assessment As MIMHassessment = assessmentController.GetMIMHAssessmentSession()
        Dim strErrMsg As String = ""
        Dim bolInvalid As Boolean = True

        With assessment
                 If assessmentController.IsAssessmentFile(strFile, .RootName, .XMLSchemaFile) Then
                    strErrMsg = "Valid Assessment file!"
                    bolInvalid = False
                    Call Me.AddAssessment(strFile)
                 Else
                    strErrMsg = Path.GetFileName(strFile) & " is an invalid Assessment file!"
                 End If
                 If bolInvalid Then
                     Me.txtErrMsg.Text = strErrMsg
                     Me.txtErrMsg.Visible = True
                 End If
        End With
     End If
  End If
End Sub

The IsAssessmentFile() function tries to load the "xml" file to see if it is in a certain format

...
xmlDataDoc.Load(strFile)

This is where I get the error.  It says it could not find the part of the path of the file. 

Like I said, it works fine on the localhost, but not on the remote server.  The remote server has been running this module fine for a while -- (ASPNET) user seems like it has the proper premissions.

I even tried to set <identity impersonate="true"/> in the web.config.  And I still get the error.  It seems like some kind of permission problem.

I want to be able to upload a file to the remote server from any of my valid drives.

I appreciate any help.
