For any Powershell enthusiasts out there, I wrote a script file that allows you to make changes to your DNS records from said command prompt. You can find it here. I'll be adding more functionality in the near future. But, this was something I've wanted for a long time. Now, I can run a scheduled task to utilize these functions to update my DNS entries in case my IP ever changes and I'm not immediately aware of it.
I hope the moderators don't mind the shameless plug. I'm hoping it will be useful to some people out there and provide more value to Dreamhost, overall.
