Not much of a network guy, so scuse my stupidity.

Webserver runs Win2K3 Server, Apache,Php,Mysql (This is live webserver)
I can RDC into server with admin permissions.

Got www folder with current website in subfolders (www/oursite)
created new folder with new site (www/newsite)

Now I want to create a subdomain (http://newsite/oursite.cn).

Tried this and some other similar post, but no luck.

Any advice?
