De que forma en un cliente se puede detectar si hay algún SQL Server en la
red? y si hay uno o más sus respectivos nombres?

Saludos y gracias de antemano.

* SQL Servers en la red

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

Private Declare Function NetServerEnum Lib "netapi32" ( _
strServername As Any, _
ByVal level As Long, _
bufptr 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

End Type

Public Sub GetSQLServers()
Dim l 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

If l = 0 Or l = 234& Then
For i = 0 To entriesread - 1
CopyMemory sv100, ByVal bufptr, Len(sv100)
Debug.Print Pointer2stringw(sv100.name) ' // Nombre Servidor
SQL

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

End Function
