        Dim lenDomain, lenSid, peUse, LastError As Integer
        Dim Win32Error As Win32Exception
        Dim pSID as IntPtr
        Dim t As TRUSTEE

        ' do a "dry run" to get the size of the SID and Domain string
        LookupAccountName(Nothing, _UserName, Nothing, lenSid, Nothing, lenDomain, peUse)
        Domain = Space(lenDomain)
        pSID = Marshal.AllocHGlobal(lenSid)

        ' do it again, for real this time
        If LookupAccountName(Nothing, _UserName, pSID, lenSid, Domain, lenDomain, peUse) = False Then
        LastError = Marshal.GetLastWin32Error()
        Win32Error = New Win32Exception(LastError)
        Throw New Exception(Win32Error.Message)
        End If

        ' Build a trustee

        BuildTrusteeWithSid(pTrustee, pSID)
