I have problem with our website, my OS is Windows NT server 4.0 proxyserver 2.0, IIS 4.0 and MS Exchange Instaled in one server. My Problem is when I open our website from outside network I cannot open it, I search the Microsoft Knowledge Base andI found Knowledge Base Article 258546 I apply it, and I can now retrieve my website but I cannot open the link that is not located on my server or located on other computer in our LAN. I can access the link on our LAN but I cannot open it on outsidenetwork? What is the problem with the webserver and how can I fix this?

Hi.
First of all let me understand. Did you put in your website a link to another computer in your LAN? And what does "the link that is not located on my server" mean?

You might want to check the permissions on the folder on the other system that you are linking to. Go to the properties of the folder and to security. The anonymous web user will be authenticated as iuser*** where*** is your servername i think. Anyway its iuser something. Make sure you have rights set up properly and also in IIS.

There are a lot of variables here. If the computer on the inside of your LAN, that the link points to, has a private side IP address, and no address translation to make it accesible from OUTSIDE your network, then you will never be able to get to it. If it has a public IP, what sort of security do you have between it and the OUTSIDE (i.e. firewall)? If there is a firewall in the way, then you need to make sure port 80 is open inbound to the computer that the web link points to.

Does the link point to an IP address? A hostname? A fully qualified domainname? What is the href tag?

You haven't closed this yet, so I might assume it is still open. After re-reading your post, I have some more questions. The IP address that your href tag is pointing to? Is it a private side address? Meaning is it something like 10.0.0.0 or 192.168.0.0? If it is in fact a private IP address, or even a public address, but one that you don't own, and therefore don't route to, then you will never be able to reach the page from outside your network.

It works from within your network because it is local, it is never routed outside. But outside of your network, there is no route pointing to your internal network which makes it unreachable. The only way to reach that address would be to use a firewall or router and have NAT translate a routable address to your local address. If you need more help or details with this, let me know.

Nine is headed in the right direction. The outside user clicking the link must get a response back to the web browsers request, so it appears that the IP address can not respond.

Needed is the design info of your network to help understand: dual nic's, dmz via firewall using NAT &/or conduits through, ect.?
