Find SBS 2003 servers in on .dk domains

The End of Life date of Windows Small Business Server 2003 is July 14, 2015. I want to find danish customers who is still running this software. A lot of these servers are running with Outlook Web Access (OWA), so my idea is to do a scan on .dk domains for servers that are open on port 443 and has a working url in this format: [login to view URL] See this url for an example: [login to view URL] I would like a script to run the scan myself or a list of these servers, so i can start contacting the companies behind them.
