Troubleshooting Code 800A0408 – Invalid Character
Introduction to Code 800A0408
This error code, 800A0408 occurs when you execute a VBScript. A wild guess a problem with an apostrophe, possibly in a ‘REM statement.
The Symptoms You Get
The script does not execute as you had hoped. Instead you get a WSH message box like this picture:
The Cause of error 800A0408
Your VBScript contains an illegal character, often at the beginning of a line. It can happen if you copy the script from word, then paste into notepad. For example, to ‘Rem out a line we need the apostrophe, which is ASCII character 39; however if you paste from word you may get ASCII 96 (Grave accent).
Note the clue Source: Microsoft VBScript compilation error, this means a syntax error in your script.
Check the punctuation marks in your VBScript, particularly look out for apostrophes and commas that do not display correctly. The reference to Line: 1 Char 1, means that the very first symbol that is probably wrong.
Example 1 of error code 800A0408 – Invalid Character

It should be ‘ Rem VBScript
‘ Rem VBScript
Set WshShell = WScript.CreateObject("WScript.Shell")
Set WshNetwork = WScript.CreateObject("WScript.Network")
Set AllDrives = WshNetwork.EnumNetworkDrives()
DriveLetter = "N:" ‘must be capitalized
RemotePath = "\\alan\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."
WshShell.PopUp "Drive " & DriveLetter & " disconnected."
Example 2 Code 800A0408 – Invalid Character
I include this screen shot just to emphasise that Char: number need not be one. Thus Char: 20, or what ever your char number is, becomes a big clue in tracing obscure characters that may have sneaked into your script.
