How do I open port 80 on Windows Server 2003.
I need to open port 80 on a Windows Server 2003. I can't figure out what it is being blocked. I have turned the Windows Firewall off, and enables TCP/IP filtering in Network Properties. I've disabled the virus protection (temporarily). I can't figure out where in the router to enable port 80. I used the following link to check the port and it says that it's still blocked. https://www.grc.com/x/ne.dll?bh0bkyd2. I need to be able to use this port for some product authentication software called "ndchealthvar". Does anyone have any ideas? Thanks.

I can't find anything blocking the connection. That's my problem. The connection is through a router and DSL modem.
And on the router port forwarding is set up to the server?

I have that enabled in the router. Attached is a screen shot of what I did.

Does it say it's 'blocked' (Stealth) or simply 'Closed'? Closed would normally mean that nothing (no software) is listening on that port.

It says Stealth.
It could also be your ISP blocking it. What kind of internet connection do you have? Do you have a working Internet accessible web server running thru that connection?
And when you check from inside your network if the port is opened? For example, do a telnet on port 80 to the server (?)

connected through a router then a DSL modem.

Are you sure the program is allready listening on port 80 (try using netstat).
Second, are you sure there isn't an other firewall/router blocking the connection? Or is the server directly connected to the internet (having a public address of it's own)?
