Nexthink Finder is a Windows-only desktop application whose functionality is now available within the Nexthink web interface. Nexthink can now be used directly from a browser and most functions no longer require an additional desktop application.
The devices in a corporate network typically connect to the Internet through a proxy server instead of using a direct connection. A proxy server, often simply referred to as a proxy, forwards the requests of client applications that run on corporate devices to the servers that run on the Internet, as if the proxy itself is initiating the requests. Then the proxy sends the responses from the servers back to the clients. By acting as an intermediary, a proxy server can provide varied functionality such as content filtering (for improved security) or content caching (for better performance).
Finders inside a corporate network that is equipped with a proxy are usually required to send their traffic through the proxy to reach the Nexthink instance. In this article, learn about the different types of proxies and configurations supported by Finder.
Finder supports the following types of proxies without user authentication:
HTTP
Finder should work out of the box with transparent proxies that automatically intercept network traffic going from the corporate network to the Internet. The client systems are not aware that their traffic is traversing a proxy.
Being a desktop application, Finder gets its proxy configuration through the Microsoft Windows Internet (WinINet) API. The WinINet API was designed to give interactive desktop applications access to standard Internet protocols such as HTTP or FTP. Other notable applications such as Internet Explorer get their proxy configuration via WinINet as well. This configuration is visible from the Internet Properties dialog of the Control Panel:
Press the WinKey.
Type in Internet Options and press Enter. The Internet Properties dialog appears.
Select the Connections tab.
Under the section Local Area Network (LAN) settings, click the button LAN settings
Choose how WinINet should configure the LAN settings (which include the proxy settings), tick either:
Automatically detect settings, to use Web Proxy Auto-Discovery (WPAD) protocol, a method to set the proxy settings automatically by leveraging the DHCP and DNS protocols. WPAD uses discovery methods in DHCP and DNS to find out the URL of a PAC file.
Use automatic configuration script, to get a PAC file from the specified URL in Address. A proxy-auto-config (PAC) file is a JavaScript file with a single function that determines which proxy should be used for each client connection.
Use a proxy server for your LAN..., to manually configure the proxy settings.
To choose whether to use a proxy or not, Finder follows the steps listed below:
Calls the WinINet API to determine the proxy to use for connecting to the Nexthink instance via WebSocket with the URL. For example:
wss://nxdocs.eu.nexthink.cloud:443
Connect to Nexthink instance either:
Through a proxy server, if the call to WinINet returned a proxy.
Through a direct connection, if the call to WinINet returned no proxy.
If the connection fails, whatever the means to access the Nexthink instance, Finder calls WinINet again, but this time with an HTTPS scheme in the URL. For example:
https://nxdocs.eu.nexthink.cloud:443
If the connection is successful, the proxy may ask for user authentication. Only basic authentication is currently supported.
If a proxy dialog appears asking for a username and password, enter your credentials.
Finder should now be connected.
