Server

Hi Guys,

Is there any way to get all available sqlservers running on a network?

Hi,
Try This: (put in a module and access it from whereever)

Code:

---

Option Explicit

Private Declare Function lstrlenW Lib "kernel32" (ByVal lpString As Long) As Long

Private Declare Function NetServerEnum Lib "netapi32" ( _
        strServername As Any, _
        ByVal level As Long, _
        bufptr As Long, _
        ByVal prefmaxlen As Long, _
        entriesread As Long, _
        totalentries As Long, _
        ByVal servertype As Long, _
        strDomain As Any, _
        resumehandle As Long) As Long


Private Declare Function NetApiBufferFree Lib "Netapi32.dll" _
(ByVal lpBuffer As Long) As Long

Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" _
(Destination As Any, Source As Any, ByVal Length As Long)

Private Const SV_TYPE_SERVER As Long = &H2
Private Const SV_TYPE_SQLSERVER As Long = &H4

Private Type SV_100
  platform As Long
  name As Long
End Type

Public Sub GetSQLServers(DomainName As String)
    '
    ' You could change this to be a function returning
    ' a list of the SQL servers in a ADOR Recordset or an array etc.
    '
    ' At present, it just does a debug.print of all the
    ' SQL servers on the network.
    '
    '
    Dim l As Long
    Dim entriesread As Long
    Dim totalentries As Long
    Dim hREsume As Long
    Dim bufptr As Long
    Dim level As Long
    Dim prefmaxlen As Long
    Dim lType As Long
    Dim domain() As Byte
    Dim i As Long
    Dim sv100 As SV_100

    level = 100
    prefmaxlen = -1

    lType = SV_TYPE_SQLSERVER
    domain = DomainName & vbNullChar
    l = NetServerEnum(ByVal 0&, _
            level, _
            bufptr, _
            prefmaxlen, _
            entriesread, _
            totalentries, _
            lType, _
            domain(0), _
            hREsume)

    If l = 0 Or l = 234& Then
        For i = 0 To entriesread - 1
            CopyMemory sv100, ByVal bufptr, Len(sv100)
            Debug.Print Pointer2stringw(sv100.name)
            bufptr = bufptr + Len(sv100)
        Next i
    End If
    NetApiBufferFree bufptr
    '
End Sub

Private Function Pointer2stringw(ByVal l As Long) As String
    Dim buffer() As Byte
    Dim nLen As Long
    '
    nLen = lstrlenW(l) * 2
    If nLen Then
        ReDim buffer(0 To (nLen - 1)) As Byte
        CopyMemory buffer(0), ByVal l, nLen
        Pointer2stringw = buffer
    End If
End Function

Hope this helps

Thanks I got it before.But I meant something else in my mind and wrote something. I will tell u what i want.

I'm getting all available sqlserver names. But if I stop an sql server and then run this API still i get the sql server name. I want to get all SQl Servers which are running in the domain. I hope u got my point.
