You would need to...
1. Enable IIS on the PC.
2. Forward/open both TCP Port 80 (IIS) and TCP Port 3389 (RDP) through the router to the private LAN
IP of the PC running IIS.
3. From the remote PC call using the public IP of the router.
http://[Your_Public_IP_Address]/tsweb
Example:
http://12.34.56.78/tsweb
For help getting IIS going, open "Start -> Help and Support" and search on the string "IIS", without
the quotes.
Look at using one of the dynamic DNS services that map a fully qualified domain name to the DHCP
assigned IP address. Typically a small program runs on the PC and contacts the dynamic DNS services
server on a periodic basis. The IP is mapped to the name and that information is propagated over the
public internet. Call using the fully qualified domain name.
Example:
http://Your.Alias/tsweb/
I use a *FREE* service from No-IP.com
http://www.no-ip.com
Others, some free some $$$$, are listed here...

When you get the login screen, simply leave the server address field blank and click the "Connect"
button.
