Publish front panel by webser, but another computer can not access it through web browser

[gq]

Hi,

I'm usiang LabView 8.5. I used web server to publish my vi front panel. The computer running labview can access front panel by browser, but other computers in same intranet can not access the front panel by browser. Does anyone can give me any suggestion?

Regards,

Gman

When you say that other computers can't access the front panel do you mean:

a) They can't connect to your server at all- the browser has a Can't Find Server error

b) They can connect to the server but the web server won't return a web page or returns a 404 "File not found" error.

c) They can connect to the server and get the web page but the remote panel can't be displayed.

If the answer is A then the problem is probably related to DNS settings on your network or firewall settings on the server.

If the answer is B or C then LabVIEW is likely misconfigured.

I believe that the remote computers have to have the LabVIEW Runtime Engine (or LabVIEW itself) running on them.  You can easily download the Runtime Engine for free from NI and install it wherever you want.  I think I heard that if you are using LabVIEW version 8.6, the Runtime Engine is not required on the remote computers, which is a big improvement.

The runtime engine is still required in 8.6 to view remote panels in a browser.

Thank you for your help. I figured out what's wrong: The Firewall in the host PC blocked the web publishing.

Hello! Here is some great information on setting up and configuring remote front panels for LabVIEW.

• Viewing and Controlling Front Panels Remotely
• Web Server Page
• Remote Panels in LabVIEW -- Distributed Application Development

Also, here are some Knowledge base articles that talk about a few common Remote Front Panel issues.

• Remote Front Panel Appears as HTML Code in Internet Explorer
• Missing Plugin Error Loading Remote Front Panel in Mozilla Firefox, Netscape, Internet Explorer, or ...
• Connecting to a Remote Front Panel that is Hosted Behind a Remote Router
• Why Can't I View My Executable Using LabVIEW Remote Front Panels?
• Front Panel of VI Doesn't Show When Client Tries to Run Remote Panel on Server

I'm running Labview 2009 SP1. 

I had the same problem (EVS 1464RT web browser remote panel not showing on computers other than development computer)

I ran an installer that had a runtime deployment included on the non working computer. That fixed my problem

Thought this might help anyone wondering if 2009 SP1 still requires runtime engine.

If you can not connect from a computer off of your LAN, it might be your router.  You can only host form behind a router if your in the Port Forwarding Rage, and your internal IP is static (aka no DHCP).
