Calling ctypes to create a custom system message

Dynamo does not include the default python/ironpython library into the script context (path)
Just add it yourself:

import sys
sys.path.append(r'C:\Program Files (x86)\IronPython 2.7\Lib')
import ctypes

I wish the dynamo team would include it by default, this question comes up very often

PS: not sure why you need ctypes, but if you only need it to create alerts/msg boxes, you are could always just use the default revit ui elements:

Alert

import clr
clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import TaskDialog

TaskDialog.Show('Title', 'Message')

With Options

import clr
clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import TaskDialog, TaskDialogCommonButtons, TaskDialogResult, TaskDialogCommandLinkId

mainDialog = TaskDialog("Hello, Revit!")
mainDialog.MainInstruction = "Hello, Revit!"
mainDialog.MainContent = """This sample shows how to use a Revit task dialog to communicate with the user. The command links below open additional task dialogs with more information."""

mainDialog.AddCommandLink(TaskDialogCommandLinkId.CommandLink1, "View information about the Revit installation")
mainDialog.AddCommandLink(TaskDialogCommandLinkId.CommandLink2, "View information about the active document")

mainDialog.CommonButtons = TaskDialogCommonButtons.Close;
mainDialog.DefaultButton = TaskDialogResult.Close;

mainDialog.FooterText = "Click here for the Revit API Developer Center"

tResult = mainDialog.Show()
OUT = tResult
