how to save credentials of network shares in windows

ur · December 15, 2016

Whenever we try to access a network share it will prompt for credentials based on the shared folder settings.

Like the below prompt

Once you save them, they are saved in Windows Credentials of Credentials Manager in Control panel (run --> control keymgr.dll).

But not able to found exact file or registry for this setting.

So, can anyone suggest how to do this process of adding network credentials using AutoIT.

Easy... put a file .bat on C:\\ .... and execute it on windows load..."Autostart". This is an old trick

But what we need to keep in the batch file is the question then.

Because I don't find any command line options to access the credential manager

cmdkey.exe

Thank you very much.

Don't know why it didn't came in Google search

To add credentials..

cmdkey /add:sharedmachine /user:domainname\username /pass:password

To remove credentials.

cmdkey /delete:sharedmachine

I will use them using run command to execute in my code.

First learn https://technet.microsoft.com/en-us/library/bb490717.aspx

Second....

local user net use d:\\server\share /user:Dan password or net use d:\\server\share /user:Accounts\Dan password

Domain net use d:\\server\share /user:DOMAIN\Dan password

Then to have persistent add /persistent:yes

One more question.

Is there any way to view these passwords??

System error 67 has occurred.

The network name cannot be found.

What you wroted in the batch, and the 4 the last question pwd look at nirsoft Network Password Recovery.

net use \\servername\ /user:~\username password

rootx · December 15, 2016

net use Z: \\ipserver\ /user:\username password

ok..for mapping the network drives right..

But I need to access the network share directly as the number of shares are more than 26

The cmdkey is working.I am able to access the share once I add the credentials to credential manager.

An AutoIt code answer (because it's a forum about AutoIt) :

DriveMapAdd("", "\\ukreddy-e7470\c$", 0, "username", "password")

rootx · December 15, 2016

ok, try the normal cmd with Admin privilege.... net use \\ipserver\ this grant you to access to all shares

Hi ur,

I prefer not to rely on external programs/tools so let me share an alternative approach to cmdkey.exe. I didn't write this, but I modified it to work for my needs. In my script I actually encrypt the password prior to storing it. Hopefully, this will make it easier for you.

#include <Array.au3>

$User = "user1"
$Password = "password1"
$AppName = "My App"
$Comment = "Used For ABC"

_Cred_Write($User, $Password) ; Write to Crediential Manager

$aArray = _Cred_Read() ; Read from Crediential Manager
_ArrayDisplay($aArray)

_Cred_Delete() ; Delete Credientials


Func _Cred_Write($User, $Password, $iPersist = 1, $Target = $AppName, $Comm = $Comment)
