Am trying the following to start a windows service
Try
Dim myController As New ServiceController("FCR GEFU Server 1", "10.1.1.208")
myController.Start()
TextBox1.Text = "Service Started"
Catch ex As Exception
TextBox1.Text = ex.Message
End Try
Am getting the following error:Cannot open Service Control Manager on computer '10.1.1.208'. This operation might require other privileges.How should I provide the log in credentials for the remote PC !?

My app (which runs ok as a standard user) requires updates to be installed, but I don't want to have to input the administrator username/password each time nor do I want to increase user privileges to administrator.
I have a windows service which handles the downloading of updates etc (running as Local System) but the start command needs to come from the main app (running as a standard user). This is not permitted and I get Access Denied.
I understand why this is happening but is there an alternative way to achieve this? I want to handle program updates as the standard user without using ClickOnce or installing to a non Program Files folder.

I've created a Windows Service and installed it via InstallUtil so I can test it out.The installation goes seamlessly, but it will not start from some reason. When I attempt to start it, I get an "Access Denied" error and that's it.
I haven't been able to find any information via the normal channels.I first thought to give the service admin rights, but that didn't work either.

I am trying to create a windows service that sits in the background waiting for programs to be started. When the programs start I want to be able to check a unique bit of information for each program (I believe GUIDs may provide this) to see what the program is. If the program is not allowed, I aim to provide a warning to the user and possibly close the program. The aim of the application is to identify when users are attempting to install additional software on to the computer so simply monitoring for a certain executable wouldn't work as msiexec is called for all MSI's and as I only want to stop blacklisted programs...this wouldn't work.

Since the coming of Windows7 at our office we have sometimes the issue that the print spool is crashing.Users don't have admin rights to restart the service so that leaves them only at restarting their computer as solution.Which costs alot of time... As we cannot find a final solution to this problem I've begin to write a small tool so they can restart it..I've only hard code a local admin account in the source for this operate for them..

when I am using the following code. the kill all batch file internally calls a vbs cript like this when a batch file is called using CreateProcess() which internaly calls a vbs script like this cscript //e:vbscript xyz.vbs which intends stops and starts a service in remote PC as follows. But the service is stopping but it is not starting event though it start command is used what could be the reason...
sCommandLine = "SC \"&strMachineName&" stop xyzService"
WScript.Echo(sCommandLine)
Set poProcess = WSHShell.Exec(sCommandLine)

We have service developed in Visul Basic .NET. This service utilizes some COM objects provided by SAP to access SAP database. This has been working fine till yesterday. On this Sunday, we upgraded the SAP system, and subsequently all other programs were also re-builded using the new DLL files (for the COM object). We tried doing the same for the service also. But it is not starting now. When started, it shows a message saying service terminated unexpectedly. This is probably due to the fact that it is not able to load the requisite DLL file.

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 am developing a Windows Service in VB2008 and am in the testing stage. What I have noticed is that if I Pause it while it is busy doing something and then resume it, the process generates an error. While I am debugging this I wanted to determine exactly what the difference is between Pausing/Resuming and Stopping/Starting a service.I searched, but most results simply told me how to Stop/Start/Pause and Resume a service, a hurdle that I jumped over many years ago. Does any one know of any resources that go into detail what happens when a service is stopped vs when it is paused?From some experimentation, it seems that if I do not place any code in the OnPause and OnContinue events the Pause/Resume commands have no effect.

I have a small service which right now I just want to test by printing some string that is passed in and stored in a class.
Problem is everything works fine, service even starts fine as long as I don't call PrintDocument's Print function.
The moment I do that, the service never starts and I get Error 1053:Service didn't respond, etc error.

In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?

I have a problem with service references, I add the reference and use code similar to the one below, in VS my app conects fine to the web service, also it runs fine launching the app directly. But after I created the installer and give to final users to install they can not connect to the web service.
a)Use service reference.
First, add service reference
Second, call it like this:[code].......

I put together a small app I want to use on my local network for service monitoring across a few of my servers.
I'm using vb.net express 2010 with system.serviceprocess imported The problem I am having is that my code only seems to work locally, and will not retrieve the service data for any server on my network.
For example, my local machine is called "office-pc", and when running the app on it, I get all the service information.
Dim localServices As ServiceController() = ServiceController.GetServices("office-pc")
For Each localservice As ServiceController In localServices
ComboBox1.Items.Add(localservice.DisplayName)
Next
But, if I want the service info from my web server called "casper", I use the same code, but i change the GetServices() parameter like so;
Dim localServices As ServiceController() = ServiceController.GetServices("casper")
For Each localservice As ServiceController In localServices
ComboBox2.Items.Add(localservice.DisplayName)
Next
After a few seconds delay, nothing happens, ComboBox2 remains empty.
It was my understanding that GetServices() would get the local machines service info unless a machine name was specified, which in both cases is true.
So why isn't it working? Do I need to set something up on the network servers first?

I am writing a vb.net client application that uses a web service to connect to the remote database.So far I am able to connect to the web service and read, add new and delete data from the database. I am having a hard time updating data.
I have a datagridview control that is bound to a dataset retrieved from the remote database using the web service.When a record is edited in the datagridview control, I need the dataset that is bound to that control to be updated and then that updated dataset to be sent to the webservice to update the remote database.
My client code in the btnUpdate_Click event
dim new_ds as new dataset = datagridview1.datasource
Dim es As New testwebservice.equipmenttracker 'the web service reference
dim msg as string = es.updateequipment(new_ds)
messagebox.show(msg)

When you create a Windows Service, you create a list of the services you want to start. The default is this:
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}
Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}
Or will that cause problems? Should we use two different classes instead?

I've got a webservice called Converter.asmx and I've just noticed that on the remote server I basically can't connect to it. The error that I get: "No connection could be made because the target machine actively refused it 127.0.0.1:49792" and the error occurs where I'm calling the web service (second line below).
Dim webservice As New localhost.Converter
results.InnerHtml = webservice.ParseData(txtInput.InnerText, options)
On my localhost it works fine. How can I change the webservice so that it'll work on the remote host as well?

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

We have a server with multiple services written in .Net 1.1 and 3.5 running on a Win 2003 server. Everything runs fine, but when we stop a certain service, an unrelated service stops. I have checked and neither has any dependencies. The service we stop is in 3.5, and the unrelated service that incorrectly stops is in 1.1. We get no error messages, nor event log errors, so we are baffled.Does anyone have an idea as to what may be causing this?

The conditions are I don't have administrator privilege I want to see the status of a service in remote machine (server)I use the following code (vb.net with framework 2.0) to see the status
Dim sqlSvc As ServiceController
Svc = New ServiceController(My.Settings.serviceName, My.Settings.machineName)
If sqlSvc.Status.ToString.Equals("Running") Then
displayStatus("success", sqlSvc.Status.ToString)
Else
displayStatus("error", sqlSvc.Status.ToString)
End If
When running the code, InvalidOperationException is raised and found out that I need admin right in the server.Can I lookup the status of the service without having admin right in remote machine ?

I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.
Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.
I wrote the sql update function in the service:
Code Snippet from web service
<WebMethod()> _
Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)
[Code]....
This displays the records perfectly and I figured out how to delete and insert records via web service.
