[AccessD] Return Names Of All Available Servers

If you mean SQL Servers see below; if you mean all types of servers 
that's a bit trickier

Sub listsql()
' For a single workstation list sql servers with  no network available
'otherwise you need to get all computer names from WMI and iterate
Dim strServer As String
Dim objWMIService As Object
Dim colInstances As Object
Dim objServices As Object
Dim objInstance As Object
Dim objLocator As Object
Dim i As Long
strComputer = "." 'local default computer name
 Set objLocator = CreateObject("WbemScripting.SWbemLocator")
 Set objServices = objLocator.ConnectServer(strServer, 
"root\MicrosoftSQLServer")
 objServices.Security_.ImpersonationLevel = 3
 Set colInstances = objServices.InstancesOf("MSSQL_SQLServer")
 i = 0
 For Each objInstance In colInstances
  i = i + 1
  MsgBox objInstance.Truename & " as instance Truename from WMI"
 Next
End Sub
