Hello Captain Obvious…
I run a small domain in my home office - I use it for all manner of things. I don’t want to pay the provider (Verizon in my case) a fee just to have fixed IP addressing. Enter dynamic DNS. Works great, less filling.
But, being a cheap bastid, how to get it to work on Server 2008? After casting about a bit, I decided to try the basics (always a good choice).
instsrv.exe and srvany.exe work just fine under Server 2008.
