NetServerGetInfo (netapi32)
Retrieves the current OS configuration information of the specified server

C# Signature:

[DllImport("netapi32.dll", SetLastError=true)]
static extern TODO NetServerGetInfo(TODO);

VB Signature:

Declare Function NetServerGetInfo Lib "netapi32.dll" (ByVal ServerName As String, _
    ByVal Level As Integer, ByRef ptrBuff As IntPtr) As Integer

User-Defined Types:

Here is how you would define the SERVER_INFO_102 structure (100 and 101 can be defined in a similar way):

<StructLayout(LayoutKind.Sequential)> _
    Private Structure SERVER_INFO_102
    Dim sv102_platform_id As Integer
    <MarshalAs(UnmanagedType.LPWStr)> Dim sv102_name As String
    Dim sv102_version_major As Integer
    Dim sv102_version_minor As Integer
    Dim sv102_type As Integer
    <MarshalAs(UnmanagedType.LPWStr)> Dim sv102_comment As String
    Dim sv102_users As Integer
    Dim sv102_disc As Integer
    Dim sv102_hidden As Boolean
    Dim sv102_announce As Integer
    Dim sv102_anndelta As Integer
    Dim sv102_licenses As Integer
    <MarshalAs(UnmanagedType.LPWStr)> Dim sv102_userpath As String
    End Structure


1. ptrBuff is a pointer to a structure of type SERVER_INFO_100, SERVER_INFO_101 or SERVER_INFO_102.

2. Pass in vbNullString as the first parameter if you are querying the local machine. Otherwise, just pass in the name of the machine.

Tips & Tricks:

Please add some!

Sample Code:

    Private Sub GetServerName( )
    Dim ptrBuff As IntPtr
    Dim strServerInfo As SERVER_INFO_102
    Dim lRetCode As Integer
    lRetCode = NetServerGetInfo(vbNullString, 102, ptrBuff)
    strServerInfo = CType(Marshal.PtrToStructure(ptrBuff, GetType(SERVER_INFO_102)), SERVER_INFO_102)
    End Sub

I have tried using NetShareGetInfo. I want to find the sharename of local machine's shared folder. Below mentioned the code snippet. The call to NetShareGetInfo always return the error code as 2310(ERROR_ACCESS_DENIED). I am not able to figure out the problem. Please help me on this issue.

public class UnManagedTrialForShare


         public static extern NET_API_STATUS NetShareGetInfo (
       string ServerName, string  NetName, Int32 Level, out IntPtr buffer);

       public static string GetNetShareInfo(string ServerName, string NetName)
         int Level = 0;
        IntPtr buffer;
        SHARE_INFO_0 shareInfo = new SHARE_INFO_0();            
        NET_API_STATUS status = NetShareGetInfo(null,NetName,Level,out buffer);
        object obj = Marshal.PtrToStructure(buffer,typeof(SHARE_INFO_0));            return ((SHARE_INFO_0)obj).shi0_netname.ToString();


[ StructLayout( LayoutKind.Sequential )]

public struct SHARE_INFO_0


    public string shi0_netname;
    public SHARE_INFO_0()


public enum NET_API_STATUS
