mapping physical path for subdomain

I have created a site in hosted environment.

my physical location c:\mydomain.com\wwwroot.

if i create a subdomain like subdomain.mydomain.com what would the physical path be?

when i create a subdomain, a physical directory is created automatically named subdomain(c:\mydomain.com\subdomain).When i try to enter a page under subdomain directory(c:\mydomain.com\subdomain\a.aspx) through writing subdomain.mydomain.com\a.aspx but i m not able to.

What configuration else should i do to enter page?

Thank u

These are all questions you would need to ask your hosting service. For one thing, never name a Windows directory with a .com in the name, it can't be accessed. Windows treats it as an executable file.
