Publish in dreamweaver

Can anyone tell me how I can publish a page using dreamweaver MX I use to use frontpage but I started to give me some troble so I thought I try out dreamweaver MX. Any help will be appreciated.

I click Publish in frontpage then I enter my website address to where I want it published then I hit the publish button on the other window and this error comes up. "The server you are publishing to does not have the frontpage server installed, and therefore does not support publishing via HTTP. To continue publishing specify a location that will work with ftp."
Can anyone tell me what this mean and how I can publish my site.

It sounds like your webhost doesn't have Frontpage extensions turned on. You may have to request that the frontpage extensions be turned on via a support ticket with your host.

On the right side of your screen, there is some option boxes that can be expanded. One is 'remote site'. You can configure how to connect to your server in there, I'm not in front of my dev box at the moment so I can't tell you the exact steps, but poke around and you'll find it.

I also get an error 550, I was wondering if thats a overwrite error? I was also wondering if I deleted my entire website and start from scratch it might work?
