Access Shared Network Folder - excel

Question

I need to access via VBA a folder hosted on a Network File Server. The folder is accessible in writing only via a Service Account (different from normal user accounts) for which I do have username and password.
Via the UI I can see that folder and map it as a local drive but in order to access it in writing I need to log off from Windows and logon via the Service Account.
Is there any way to access the network folder during a normal user session but hardcoding username and pwd in the VBA code?
I did try mapping the folder as local drive with:
Set WshNetwork = CreateObject("WScript.Network")
WshNetwork.MapNetworkDrive "S:", "\\corp-server\HostingFolder", False, Username, pwd
but did not work ("S" drive was not mapped). If instead I do the same but without providing Username and password:
Set WshNetwork = CreateObject("WScript.Network")
WshNetwork.MapNetworkDrive "S:", "\\corp-server\HostingFolder"
it works perfectly.
Wondering now if what I am trying to do is actually possible? If not, is there any alternative?
Thanks

You might find this answer of value in your testing.
Essentially, I would check a couple things...
Make sure you are not already connected to this resource using the current logged in user. If you are, you might get an error message like the following:
Make sure you are using the domain\username syntax in your username.
Otherwise I think you are the right track. I put together some sample code based on the link above, and was able to successfully connect to a network share under a different user name and iterate through a list of files.
(Note the tip that you don't actually have to map a drive to establish a connection.)
The following code is a really quick (working) VBA implementation of the sample listed at Access network share from within VBScript eg FileSystemObject
Public Sub TestNetShareName()
Dim NetworkObject As Object
Dim FSO As Object
Dim Directory As Object
Dim Filename As Object
Dim ServerShare As String
Dim UserName As String
Dim Password As String
ServerShare = "\\corp-server\HostingFolder"
UserName = "mydomain\myuser"
Password = "freddie123"
Set NetworkObject = CreateObject("WScript.Network")
Set FSO = CreateObject("Scripting.FileSystemObject")
NetworkObject.MapNetworkDrive "", ServerShare, False, UserName, Password
Set Directory = FSO.GetFolder(ServerShare)
For Each Filename In Directory.Files
Debug.Print Filename.Name
Next
Set Filename = Nothing
Set Directory = Nothing
Set FSO = Nothing
NetworkObject.RemoveNetworkDrive ServerShare, True, False
Set NetworkObject = Nothing
End Sub
