Running a dynamic dns updater software on Windows server 2008 R2, when I log off the software stops updating, I concluded that I have to look for a dynamic dns client running as service, I found this task a bit heavy since there is a big variety on the net, it needs a long time to make the right choice as many details are to pay attention to, free, masked fees, fees, installed on machine, configured on router, trusted, not trusted, compliant with OS, not, ...
That's why I am here to ask for help on this matter, I would like to be advised by skilled people, to find a trusted free dns updater (client) for Windows which can run as service, and maybe which can send email when update fails.
