[RESOLVED] Enable Disabled Windows Services

Dear All,

1- I am using C# 2

2-I need a way to start disabled windows xp Messenger service(on client pcs) from C# Application(on windows 2003 Server), so "net send.." instruction works.

3- Service Controller Component start the service if it is not disabled.

4-if it is not possible(step 2) , Is there a way to send a message to clients pcs on the LAN from C# Application other than (net send ..)??

thank you all

You have to edit the Registry to enable or disable a Windows service. The key you need is "HKLM\SYSTEM\CurrentControlSet\Services\<service name>" and you need to set the Start value. I can tell you that a value of 2 corresponds to a Startup Type of Automatic. If I remember correctly o is Disabled and 1 is Manual but you can check that. Here's a method that I wrote in VB.NET to make sure the Distributed Transaction Coordinator service was running:

vb Code:

Public Shared Function EnsureTransactionManagerStarted(ByVal setAutoStart As Boolean) As Boolean
    Dim result As Boolean
 
    Try
        Dim msDtcController As New ServiceController("MSDTC")
 
        'Make sure the transaction coordinator is running.
        If msDtcController.Status <> ServiceProcess.ServiceControllerStatus.Running Then
            msDtcController.Start()
            msDtcController.WaitForStatus(ServiceControllerStatus.Running)
        End If
 
        result = True
    Catch ex As Exception
        ErrorLogger.Log(ex)
        Debug.WriteLine(ex.ToString())
        MessageBox.Show(My.Resources.StartMsDtcServiceFailedErrorString, _
                        "Start Service Failed", _
                        MessageBoxButtons.OK, _
                        MessageBoxIcon.Warning)
        result = False
    End Try
 
    Try
        Dim keyName As String = My.Resources.MsDtcRegistryKeyPathString
        Dim valueName As String = "Start"
 
        If setAutoStart AndAlso CInt(My.Computer.Registry.GetValue(keyName, _
                                                                   valueName, _
                                                                   0)) <> 2 Then
            'Set the start-up type for the Distributed Transaction Coordinator service to Automatic.
            My.Computer.Registry.SetValue(keyName, _
                                          valueName, _
                                          2)
        End If
    Catch ex As Exception
        ErrorLogger.Log(ex)
    End Try
 
    Return result
End Function

You can get the idea from that and apply the same principles in C#.

2 for automatic, 3 manual , 4 disabled

Thank you
