iam hosting my website on IIS. I am able to access the website via localhost and the system's IP address, but iam unable to access it outside of my local network. I am able to remotely control that machine using mstsc.

I believe that the firewall is completely disabled. What could be the cause of this?

Not very clear. Let me summarize it. You have:
-------   LAN   ------------   WAN   ------------
| IIS |---------| Firewall |---------| Computer |
-------         ------------         ------------

Is this correct?
And you say, from Computer you can access IIS with RDP, but not it's website?

The reason should be that, on the firewall, there is a NAT (Network Address Translation) rule that redirects incoming packets on port 3389 (rdp) to IIS Server.
If you want to also access the website, then there should be a rule for port 80 (http) and/or 443 (https).

It could also be possible that your website is listening on address (localhost), but not on LAN address (which I don't know). You can fix that in IIS MMC console. Not it can't, I misread and thought the site were only accesible through localhost.

5ed. Also, it's possible that IIS is not exposed to WAN at all.
"I am able to access the website via localhost and the system's IP address" is not clear. Access from where? "Via localhost" means that this is still done from the same computer... :-)

It means that it is working when accessing the site through or, obviously on the same computer. But if it is working locally with LAN address, then it should work on every other equipment on the same LAN segment. At least, that is the way I understand the issue :)
I know, but it would be impossible to connect to from WAN anyway. That's the point. What I meant is: it could be literally written "http:/localhost", which would also work, but only on the same computer. Or it could be LAN address (which is not really localhost). The expression is not clear, OP should be requested for clarification.

OP does not seem to have read the answer. Or at least did not answer to clarification request. Time will tell :)

So read my answer, as this is exactly what I understood.
If you have acces to the firewall (and the right to do it), then add some NAT rules for ports 80 and 443. Otherwise, talk to your admin and see if it is possible. As you are behind a firewall, there is no other choice if you want a webservice in your lan to be accessible from outside.
