how to save credentials of network shares in windows


ur
 Share

Recommended Posts

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

Signature - my forum contributions:

Spoiler

UDF:

LFN - support for long file names (over 260 characters)

InputImpose - impose valid characters in an input control

TimeConvert - convert UTC to/from local time and/or reformat the string representation

AMF - accept multiple files from Windows Explorer context menu

DateDuration -  literal description of the difference between given dates

Apps:

Touch - set the "modified" timestamp of a file to current time

Show For Files - tray menu to show/hide files extensions, hidden & system files, and selection checkboxes

SPDiff - Single-Pane Text Diff

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

I am getting the below error when I try the net use

 

System error 67 has occurred.

The network name cannot be found.

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.

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
