I've spent alot of time digging thru the forums to research this problem, and to get the right code. I'm wondering now if this is a system configuration problem, or something else with my code.
Firstly, i'll tell you that i've already put the service account on my machine local security policy that says 'allow to act with/as operating system'.
Running this code from an application, it works just fine:

I have to admit that I was sceptical it would work... but below is the code. I had to make a minor change to the code you suggested. Whenever I tried IPC$ it would return a 53 result code, even though I'm sure the share exists. So at the suggestion of another website I removed the share and just the computer name and this worked.
Imports System.Runtime.InteropServices
Imports System.Net
Imports System.IO

I'm attempting to consume a HTTP Basic Auth Secured PHP WebService using VB.NET. I've so far managed to get 100% perfect integration by adding it as a Web Reference and doing the following:
Dim Credentials = New System.Net.NetworkCredential("username", "password")
Dim CredentialCache = New System.Net.CredentialCache()
CredentialCache.Add(New Uri(MyWebService.Url), "Basic", Credentials)
MyWebService.Credentials = CredentialCache
MyWebService.PreAuthenticate = True
I can also successfully add the webservice as a 'Service Reference' and this also works fine, as long as i turn off all HTTP authentication on the SOAP server.
My problem is that I can't find any documented means of sending basic HTTP Auth Credentials when using Service References as opposed to 'Web References'
Am I right in my understanding that 'Web References' are a legacy method of Web Service consumption?
I was able to programmatically launch a service on my development server from a workstation using the ServiceController class with no problems.
When I try to programmatically launch the service on my production server from my workstation, I get an access error which means I do not have rights to run the service with my logged in ID on the workstation.
My question is, is there a way to launch the service using different credentials? I do not see anywhere to input these credentials in the ServiceController class.
When I try to call a [Java] web service from .NET, I am getting what appears to be a security credentials issue. CWWSS5509E: A security token whose type is [http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken] is required.Is it even picking up the credentials that I am trying to pass? At this point, I just want to make contact with the web service and get access. In my example, ServiceReference1 is a generated Web proxy class.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

I am developing a small tool to allow our Windows admins to do stuff like create/delete users, mailboxes and other useful stuff.The current version has to be launched with RunAs as it requires domain admin privileges to do a lot of the stuff. Now, to overcome this I'm trying to incorporate a dialog box that prompts for credentials when the application starts and then uses said credentials throughout the application. I have it working for the AD interaction but one of the tasks the tool needs to do is create folders on a remote server and share them.Is there any way to create folders using alternate credentials? Maybe, once I have the credentials, quit the application and re-launch it with the specified credentials?

Ideally I'd like to be able to copy/move between an accessible folder on my local drive and a network share that I don't have permission to access (but the application would). I am using impersonation to give me access to the files in the network share but using System.IO File.Move or File.Copy forces me to use the same credentials for each location. Is there a way around this?

My first post as an absolute last resort. In 8 years of programming, I have never posted to a programming forum and have always been able to wiggle my way out of any diffficult project...Until this project.Every step of this project is new for me (Windows service, ini file, IIS, FTP, cmd line params, comparing file specs programmatically, using a timer, and even VB.NET is still confusing to me after several years in VB6 ). Dreading posting b/c I have so many questions. I have finished the internet, been to the end and back. Found endless suggestions of code and links and forums and only gotten more lost in the process.
I am trying to create a VB.NET app, that most likely will need to be a service, for our external clients' PCs. These PCs are not connected to our network. This app will be invisible to the user and will need to perform several tasks including:

View 1 RepliesI thought that creating a simple system service under VB .NET would be a piece of cake. Boy, was I wrong. First, I find general postings through Google that say you should use the Windows.Forms.Timer. Then, I found conflicting information that says you have to derive the timer from a timer class through code to make it work. Then, people are reporting all sorts of trouble using the various types of threads available. I can't debug threads using the VS 2010 Just-in-Time debugger for obvious reasons (although, I don't know if there is an alternate method to doing this).My project is an application launcher (similar to cron) that will fire off periodically within a certain amount of seconds. I am trying to use the Process.Start() method. I have a Beep() function as the first instruction, and the Process.Start, along with a Process.WaitForExit method to make it block as the last instruction. I had my code doing this through timers, but now I am starting to use threads. No difference in execution. The over-ridden OnStart method does kick off (as I am certain through debugging), but nothing ever happens when starting the service in production, as if it were ignoring all my code. Putting loops and logic in the OnStart method yields a process that won't start. I know it is a threading issue, but I also know it must be mandatory to use threads. I am now dumbfounded as to how to make this work. I am curious to know the solution.
In addition to the service class, I have a ServiceInstaller and ProcessInstaller implemented that I copied verbatim from MSDN.Here is some of the code I am trying to work with. Note that this simply reflects the current state of my code in trying to implement the logic within a thread instead of a timer (which to me would be optimal):[code]
What I am looking to do is write a VB.NET program, as a service that reports anything on client1 that I want (say the fact it is online) to a database on the internet, so I can look on management1 and see the online status of the machine (assuming management1 has a connection to the online database).
What is being reported doesn't matter, what I am looking at is a starting point to create a system like that. I have googled obviously and come up with nothing, I'd just like a "starting point" or some documentation to look at for creating something like this. The service doesn't look too difficult but the periodic reporting of online status or ANYTHING to any kind of database is not something I am sure how to deal with.
I already have setup a VBS that reports information to an ASP script that then places it in a database but I don't know how I would create say a "keep alive" connection for a vb.net service.
i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

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.
