Troubleshooting Code 800704B3 – No network provider

Introduction to Error Code 800704B3

This error code, 800704B3 occurs when you try to map a network drive with a VBScript.  You are probably using a WSH method called MapNetworkDrive.Code 800704B3 No network provider accepted the given network path

The Symptoms You Get

The script does not execute as you hoped, instead you get a WSH error message.  The probable scenario is that you are trying to create a Windows logon script.

Note: This is similar to: 800704CF – No network provider.  The difference is that 800704B3 indicates a problem with share, while 800704B3 means there is a problem with the server name.

The Cause of Code 800704B3

Either the ServerName in your script does not exist, or it is offline at this time.  There are two clues in the Windows Script Host message box,

Note Error: No network provider…… .

Note the Source : WSH.Network.MapNetworkDrive.

Tim’s Suggestion
The error could be caused by a slow network card.  Symptoms, the script works the second time you run it.

Guy / Tim suggested solution add a sleep command for example:
WScript.Sleep 500


The Solutions

In the example you would check Line 14 in the script that references the ServerName.  PING the ServerName, open a CMD shell and type: net view.  Look for clues particularly the Line: number.   Char 1: often lies! it just means that the whole line will not execute. In the case of runtime errors you can use this work around.  Add this line: On Error Resume Next.

A nasty variation of this error is where you add an extra \slash\ in the path. 
See Example 2.

Example 2 of Error 800704B3

Note the error – RemotePath = "\\ alan1\home\" 

it should have one less \slash \\ alan1\home"

Set WshShell = WScript.CreateObject("WScript.Shell")
Set WshNetwork = WScript.CreateObject("WScript.Network")
Set AllDrives = WshNetwork.EnumNetworkDrives()

DriveLetter = "N:" ‘must be capitalized
RemotePath = "\\alan1\home\"

AlreadyConnected = False
For i = 0 To AllDrives.Count – 1 Step 2
If AllDrives.Item(i) = DriveLetter Then AlreadyConnected = True

If AlreadyConnected = False then
WShNetwork.MapNetworkDrive DriveLetter, RemotePath
WshShell.PopUp "Drive " & DriveLetter & " connected successfully."

WShNetwork.RemoveNetworkDrive DriveLetter
WshShell.PopUp "Drive " & DriveLetter & " disconnected."
End if &nbsp
