Workaround for a win2008/win2012 DNS server startup bug: errors 404,407,408 at system startup.
See https://www.google.ru/search?q=win2008+win2012+dns+error+404+407+408 for the bug discussion. For specific links, see e.g. http://forums.petri.com/showthread.php?t=62255 and https://social.technet.microsoft.com/Forums/ru-RU/374112f8-f8a5-4eb8-8682-2a54b2de601f . This fix is for the case when there's nothing special on the server (no multihoming, virtualization etc.) - the cause appears to be that TCP/IP is not yet fully functional when the `tcpip' service reports it has started.
The script searches DNS server event log for the specific errors that have occured during the current startup and restarts its service if there are.
- Install Python 2.7 and modules: pywin32, iso8601, lxml
- Copy the script to what will be its working directory (the log will be placed alongside the script)
- Install the script as a service to run delayed and as Local System:
(path)\dns_fix.py --startup=delayed install - start the service and check the log to confirm it works as expected (the service exits after finishing its work)
