Cannot access application under IIS from another PC

Hi everyone,

I have a little "problem" with one of my IIS-website. I have made a new website under IIS with an application under it. The application is the spam-quarantaine management from GFI mailessentials.

It works this way: Every hour, the users are send a report of the spam quarantaining. They receive a link on which they have to click and then they are guided to the IIS-website. The problem is that when I click on this link on the server running the IIS-website, everything works great. But when I go to this website using another PC, it just doesn't work.

I have set the following binding:
Type: HTTP
IP-address: All Unassigned
Port: 20000
host name: server (same name as the server is called)

It works from the server, but not from the other clients. What do I have to do to give other computers access? I am new to IIS and don't know my way around it that good..

Thanks in advance!

can you ping the server from the other computers? netnet on port 80 is working?

ipconfig /flaushdns?

- another setting on IIS bindings could be to change from "All unassigned" to specific IP
- then check, if there is no FIREWALL inbetween. Is this 2008 server? You must allow TCP port 20000 in on firewall, for all scopes.
- how does link look like? is it http://servername:20000/something or ? Check host-headers value in IIS if accessing by servername - host-header should match your server name in the link and in the IIS binding properties.

Thanks Labsy, it was indeed the firewall port that needed to be opened. Should have tried this first, thanks for the solution!
