Check user authentication to windows share

Hello everyone.

I'm trying to connect to a windows share (\\print) but if my authentication fails, for example, wrong username or password, how can i catch that error?
The problem is that when executing the script (exe. file), if i insert wrong credentials, the error message is from Autoit program and not the message i would like to pop up (code above) if there is some problem with the authentication.

Here is a sample of my code:

The values of $username and $password are filled from an Inputbox.
So, after that code i tried to catch the error like this:


And by the way, the error i got from the console is this one:

C:\Users\user\Desktop\test.au3 (33) : ==> The requested action with this object has failed.:
$WshNetwork.MapNetworkDrive( "","\\print",True, $username, $password)
$WshNetwork.MapNetworkDrive( "","\\print",True, $username, $password)^ ERROR

Well, the error is happening, but is there some way to catch the error from the code and send an alert (Msgbox)?

Thank you for your help and time,
Sardinha
