How to upload file in external ip address vbscript - file-upload

Question

I'm using vbscript in asp classic. I also used the FreeASPUpload class.. I want to upload file not in local, but to a server using its IP address as path..
Here is the code working if i will upload in local..
Dim uploadsDirVar
uploadsDirVar = Server.MapPath("../temp/")
Set Upload = New FreeASPUpload
Upload.Save(uploadsDirVar)
But i want to upload it in a path with an ip address.. Below are the codes I tried but its resulting in HTTP 500 Internal Server Error..
Dim uploadsDirVar
uploadsDirVar = "\\123.45.6.789\DocFolder\"
Set Upload = New FreeASPUpload
Upload.Save(uploadsDirVar)
I already mapped the folder \123.45.6.789\DocFolder\ in my local because of the login. I also tried codes with credentials but still same error.. See below:
Dim ServerShare
Dim UserName
Dim Password
Dim NetworkObject
Dim FSO
ServerShare = "\\123.45.6.789\DocFolder\"
UserName = "domain\username"
Password = "password"
Set NetworkObject = CreateObject("WScript.Network")
Set FSO = CreateObject("Scripting.FileSystemObject")
NetworkObject.MapNetworkDrive "", ServerShare, False, UserName, Password
Dim uploadsDirVar
uploadsDirVar = "\\123.45.6.789\DocFolder\"
Set Upload = New FreeASPUpload
Upload.Save(uploadsDirVar)
Still same result.. Can anyone help? I'm new in asp classic and vbscript especially in uploading of files and also its behavior. thanks

Your website in IIS typically runs under a machine-specific user account for IIS (IUsr_computername). It won't have any privileges on the remote machine you are trying to access over the network. You need to create a user in a domain that both your IIS machine and the remote share are in, and set that website to run as this new domain user. You can then give that new domain user privileges to read/write in the folder you're sharing on the remote machine.
