Logon Failure : Unknown User Name Or Bad Password
Feb 8, 2012
I am using VB.NET 2008.
On this Windows 7 Professional SP1 machine, when I run the following code in the program
FileCopy(sServer & "loglog.txt", Application.StartupPath & "log.txt")
I got the error "Logon failure: unknown user name or bad password."
sServer is 1 of our server machine.
The Windows 7 machine already logged in to the sServer as administrator, and it also login to the Windows 7 machine as administrator. I run the VB program as Administrator (right click - Run as Administrator).
In the Windows 7 machine I can go to Windows explorer and copy the file manually from the sServer machine to the Application.StartupPath folder.

When my application starts, one of the first thing it does is load a list box with data from an Excel file stored on our server.To prevent an issue I had with two or moreengineers trying to load the data from the same file at the same time, I added code that copied the Excel file to a temporary file (which is,hen, deleted when the data load is done).This has been working fine up until last week. Last week our company moved to a new building.The move included servers and all. Suddenly I'm getting inundatedwith complaints from engineers about my application.It seems that they started getting the following error

I created a program with all our clients user name's and password that will be used to log on a web page from our company so i can modify there settings. So far so good i created a form with a combo box to pick a name and then a simple click on the button opens form2 with a browser in it. This browser automatic logs on the page it loads. You should say mission accomplished and we are done........ not yet this stupid page got something nasty in it. If i want to open our clients reports it opens in a new browser and this is something i can't change. So basically what happens if i click the report it opens in the standard user defined browser installed on my machine. This means i get a log in screen again cause my session is in the VB.net browser.
Let me show the code i use at moment that i use to auto log on. For some reasons i did cut out the URL's out of my code. (privacy, security etc.)

Imports System.Data
Imports System.Windows.Forms

I am currently creating a tool that can manage local user accounts on Windows-PCs. I am using the functions described on
this MSDN page ; and after some struggling, I got most of them to work.
Unluckily, I haven't found a way to set the option "User must change password at next logon" while creating a new user account. I use the
NetUserAdd -Function to create the new user. I set the level to 1 and supply a
USER_INFO_1 -Structure . This structure accepts flags, and the flag UF_PASSWORD_EXPIRED seems to be exactly what I want - but when I set it, the user can log on without changing the password first...
I'm developing on Windows 7 Ultimate 64-Bit using Visual Studio 2010 Express.
Here's my code:
#Region "Constants"
Public Const UF_PASSWORD_EXPIRED As Integer = &H800000
Public Const USER_PRIV_USER As Integer = 1

I am trying to figure out a way to change the SQLSERVERAGENT service Logon password with one of my VB2008 applications. I can't seem to find any place in the registry were the password is stored and can find any solution other than manually going into the service and changing it myself.

I would really welcome some help with this issue. We have a php code that works and connects to the LDAP. When I try to connect using VB.NET 2010, it fails to bind with logon failure unknown username or bad password. Below is the connection information. When I talk to the folks who run the ldap server, they say I am binding sucessfully, below is the log file for the sucessful bind? If I continue and try to execute a search I don't get any results. The server is running openLDAP ver 2.3.39 on a linux server, server requires connection on port 636 for secure connection, or 389 for anonymous.

This might seem obvious but I was doing some research and I was wondering if a service application start an executable. I know an .exe cannot start without some sort of logon but I was wondering if it was possible to work around this by having my service call it.

I'm working on upgrading a solution in VB.NET that is heavily based on Active Directory. As of now, I'm trying to add a PC restriction to a new AD User upon user creation. Essentially, I need to update the Logon To attribute to include 1 or more PCs, how do I go about doing this? I learned that I am interested in the IADsUser property "LoginWorkstations" url...). As of now, I have code that can fetch this attribute from any AD user, but I cannot set it. [code]I've tried testing this approach with a different attribute and it works just fine. Not much out there on Google either unfortunately.

I am wanting to create a logon similar to the Windows Live logon, so in other words. user has frmLogon and is located in Australia. The user enters his/her details and then the program connects to a server in the United States and checks the Username and Password to make sure it is correct if it is correct it allows the user to logon and move to the next stage, if it is wrong it will give him an error message. I am wondering if anyone has a tutorial or source code laying around that I can rip apart and see how it works. I want to put the database on my server and connect to it from my desktop using the logon form.

Using Access 2003 and VB code, I have created a form with a number of labels. The labels will display an employee's names. I have named the labels name1, name2, name3...etc. Using an ADO data set and DCount I have determined the number of names in an Access table (the number of names can vary). What I want to do is for each record in succession to pick the first name and surname from the data set , combine them into a full name (this part has been successful), and then set the full name into the label caption in succession. Example: full name 1 into name1, full name 2 into name2, full name 3 into name3... until all names appear as labels on the form.
I created a counter to and a variable to increment the label number but when I address the caption property of the variable containing the new label (e.g. name1, name2..etc.) it throws an errer at runtime. Here is the code:

I have listBox control of user objects where each object has userName and Password.What I want to do is when a user enters userName and Password a method goes through the listBox checks for whether userName exists or not and if userName exists then matches the password.What I have in my mind is that to use for each loop but I think it would become complex so is there any better way?

But if it does not have a password, passing an empty string does not work. It fails each time.I've been looking around, but haven't been able to find much on this. Does anyone know how to determine if the user password is empty?[code]

I'm working on a vb.net application connecting to mysql db which will have alot of users using it.
How should I deal with the user registration?I mean, I used to create a table with a username and password fields to store the users data in it, but in this case all the users will connect to the database with the same username and password of the server (in the connection string)
I need a pointer on how to do this thing right.What would happen if many connections established from many computers with the same user and password in the connection string?
