Lo mas parecido que conozco es el selector de recursos de la red, un cuadro de diálogo que usa win. Aca te mando el código:
Option Explicit
Private Declare Sub CoTaskMemFree Lib "ole32.dll" (ByVal hMem As Long)
Private Declare Function lstrcat Lib "kernel32.dll" Alias "lstrcatA" (ByVal lpString1 As String, ByVal lpString2 As String) As Long
Private Declare Function SHBrowseForFolder Lib "shell32.dll" (lpbi As BrowseInfo) As Long
Private Declare Function SHGetPathFromIDList Lib "shell32.dll" (ByVal pidList As Long, ByVal lpBuffer As String) As Long
Private Declare Function SHGetSpecialFolderLocation Lib "shell32.dll" (ByVal hWndOwner As Long, ByVal nFolder As Long, ListId As Long) As Long
Private Type BrowseInfo
hWndOwner As Long
pIDLRoot As Long
pszDisplayName As Long
lpszTitle As Long
ulFlags As Long
lpfnCallback As Long
lParam As Long
iImage As Long
End Type
Public Enum BrowseType
BrowseForFolders = &H1
BrowseForComputers = &H1000
BrowseForPrinters = &H2000
BrowseForEverything = &H4000
End Enum
Public Enum FolderType

CSIDL_PERSONAL = 5
CSIDL_PRINTERS = 4
CSIDL_PROGRAMS = 2
CSIDL_RECENT = 8
CSIDL_SENDTO = 9
CSIDL_STARTMENU = 11
End Enum
Private Const MAX_PATH = 260
Public Function BrowseFolders(hWndOwner As Long, sMessage As String, Browse As BrowseType, ByVal RootFolder As FolderType) As String
Dim Nullpos As Integer
Dim lpIDList As Long
Dim res As Long
Dim sPath As String
Dim BInfo As BrowseInfo
Dim RootID As Long
SHGetSpecialFolderLocation hWndOwner, RootFolder, RootID
BInfo.hWndOwner = hWndOwner
BInfo.lpszTitle = lstrcat(sMessage, "")
BInfo.ulFlags = Browse
If RootID <> 0 Then BInfo.pIDLRoot = RootID
lpIDList = SHBrowseForFolder(BInfo)
If lpIDList <> 0 Then
sPath = String(MAX_PATH, 0)
res = SHGetPathFromIDList(lpIDList, sPath)
Call CoTaskMemFree(lpIDList)
Nullpos = InStr(sPath, vbNullChar)
If Nullpos <> 0 Then
sPath = Left(sPath, Nullpos - 1)
End If
End If
BrowseFolders = sPath
End Function
Ejemplo de uso:

Si esta bien,pero como cogo los nombres de los equipos para trabajar con ellos.
Gracias

Eso solo es para los recursos de la red, yo te dije que era la única api simple con que listarlos. Proba con lo siguiente (sobre win NT/XP solo me lista los grupos, lo tendrías que modificar para centrarte solo en un grupo):
