Pass Credentials When Accessing UNC Share?
Nov 15, 2009
I am trying to readwrite to a UNC share from a machine that is not on the corporate domain. I'm performing a mkdir(UNCpath) command and I'm also writting by using an xml.save(UNCPath) command.
The problem is that users who are not on the domain are getting permission errors when attempting to access the unc share.
Is there a way to pass credentials automatically when attempting to access the UNC share.
I've read a bunch of posts and people have suggested mapping a network drive then writting but I would only like to do this as a last resort.

I have a program written in VB.net 2003 that are folks run under alternate credentials. Inside the app there is an option to open a UNC path to a network share. We were running Windows XP SP3 and IE6. The code is simple just a call to the explorer.exe with /root,\UNCPath. After installing IE 8 onto the machine this no longer works. Best I can tell the code is still working but now being executed in non interactive mode so nothing opens up. You can however see a new spawned explorer.exe running under the system account for each attempt at opening a UNC Path. Any ideas what IE8 could have done to cause this behavior?

Dim LogonCred as net.credential= New Net.Credential(userid,password, domain)
Dim DestUri as Uri=New Uri(file://192.168.86.1/c$/Program Files/Test/Test.xml)
My.Computer.Network.UploadFile("d:Test.xml",DestURI,LogonCred,False,3500)
This passes credentials of my local machine (which is not part of the domain) instead of passing the LogonCred.Is this function just broken? Or is it my code?

(System.IO.File.Move(SourcePath & Filename, TargetPath & Filename))Impersonation will not work neither will mapping a drive (As no user will be logged on)This is a console application that takes the above parameters.

I've been looking at accessing shared folders, read and write, via the network without being prompted by the OS for the username and password.
On this forum, and googling, I can find many things about accessing network shares, but none using code which also passes the username and password required.
What I'm basically looking for is to not have to map a drive on the users computer. Then using code, write or read files from a network share and at the same time pass the username / password required for that network share.

I'm developing a web application that requires the user to log in using forms authentication. inside the webpage you need to download a desktop application that requires to login to the same system too. Is there a way to transfer the current logged credentials from the web application to the windows desktop application without need to login again?. Both applications shares a Login object from an vb.net interface.I tried to save the IP address in the Database but that don't work for me because the website needs to be accessed inside and/or outside of the company and the user cannot login twice in different machines.

I want to download my update files for my program from an FTP server, but i need to login first with the credentials. I have tried many things, used some examples on MSDN, googled a lot, but i can't find the code that i'm looking for... I also use a DLL of someone that i've imported into my project. I don't know if that harms my part of being unable to log in.
I have ZERO experience with FTP servers or Network Credentials, i've learned the little things about it on google.

I have a routine that sends an email via SMTP. I'm using googles smtp server - "smtp.gmail.com". I'm using my gmail email address/password as the authentication credentials. My webpage form consists of the following fields:
"User's Name"
"Organization"
"User's Email Address"
"Subject"
"Memo"
In testing this functionality, I've found that my problem is that when the email is sent, it uses my authentication email address (my gmail email) instead of the "User's Email Address". If I can't see the User's email address, this functionality is useless.
Here is my code below.
Private Sub FormatEmail()
Dim Email_Sent As Boolean = False
Dim toEmail As String = "blakemc@mail.com"

I am writing a program which will require a user to login with a different account from the one they use to logon to the computer with (as they have a normal account and an admin account). The program needs to run under their admin account.
I have made a login dialog that authenticates them ok, but my question is is there any way to make another form run under the credentials typed in on the login form? i.e program loads up the login form, but there after the program uses the credentials supplied in the login form.

I am trying to "behind the scenes" log myself into a website, from the VB code behind my ASP.NET website. But I am dumbfounded as to how to do this.
As far as I know I should be using the WebRequest or Webclient class. That is about as much as I know. I am not sure how to use the class.
I want to click a button on my website and have its Click event send a username and password to another website. This other site isot affiliated with mine. I realize the concept may seem stupid, but I plan on taking this further later, but Just need to know this now.

I want a supervisor override capability for my application.I want to provide a username login prompt (including domain). If the user is in the approved list and the password correct, show advanced controls.What .NET code / functions allow this?
NOTE: VB.net answers preferred. C# also accepted.
EDIT: the logged in user is not the user authorizing the override.

We don't want to get the password, we only want to store the user credentials so when they do work on the application we can apply their usernameto each operation and when they are done with an operation and do a digital signature by scanning their badge we want to compare the user's credentials with the stored credentials to ensure the user has logged in and is the current user.1. User 1 logs into the program using their username/password for windows.5

Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController
[code].....
I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.

I need to open a folder on a remote server with different credentials in a window (explorer.exe).I managed to do it with no credentials (my credentials), but when I do it with another username and another password than mine, it opens a prompt to enter a username and a password, and it says "access denied".
In the access log on the remote desktop, it says that I tried to connect with my own username, and not the other username I entered. So, the process obviously did not work.

I have multiple web applications that I've built for our intranet. I wanted to allow users to not worry about logging in, so these apps pull the currently logged on user when they hit the site. I used this code for this to happen:
Dim userName As String = User.Identity.Name
CurrentUser = userName.Substring(userName.IndexOf("") + 1)
This works like a charm, no issues here. The next step is to query Active Directory for that logged in user to pull various information. How I currently have it coded, it works like a charm on the devleopment side (typical because I'm not running IIS).The problem becomes when I publish it to my IIS server (Windows Server 2008 R2 running IIS 7.5), I get error messages that point to the specific line in my code that queries Active Directory. The interesting part is these apps were working great last week. They broke after my server admin did the latest batch of Windows Updates (please note, I am running them using .Net Framework 4.0)Before I had each app setup so that Windows Authentication was Enabled, the other Authentication types were disabled. For providers, Negotiate is #1, NTLM is #2. For Advanced Settings, Extended Protection = Off, and Enable Kernel-mode authentication is checked.

In doing this I also removed the string that was higher up in my web.config section. This did not work either (fyi, this was a great reference[url]I then tripped across this article: [url] which seemed to be a similar situation. This article eventually referenced "Double Hops", after looking into this and trying a few things, this didn't solve my issue either.Next StepI am going to try a new IIS 7.5 implementation on a different Server 2008 R2 system and essentially start from scratch, to see if the problem recreates or not.

i'm doing everything by the book, but the .NET client is simply not sending an authentication header when making requests to my (PHP) SOAP Web Service. I have verified this by logging the raw post data at the PHP end of things and .NET never sends any auth headers.This is the code I am running before making calls on my ExampleWebService Web Service:
ExampleWebService.PreAuthenticate = true;
NetworkCredential myCred = new NetworkCredential("myusername","mypassword");
CredentialCache myCache = new CredentialCache();
[code]....
As I understand it, PreAuthenticate should force the sending of my HTTP Basic Auth Credentials on every request regardless of challenge. Does this only work with IIS hosted services?
