Using FrontPage to Upload Content to a Website Hosting Multiple Domains
If your account hosts subdomains or non-primary domains and you use FrontPage to publish content, you should only upload content through your account's primary domain. Connecting to the non-primary domain or subdomain directly can result in the corruption of files and affect the behavior of your Website.
To upload content for a subdomain or non-primary domain through FrontPage, first connect to your primary domain, and then navigate to the subdirectory that houses the subdomain or non-primary domain content before publishing.
