If this is successful, WPAD will work for the computer this browser is on.

If Step 2 above is successful, test to see if the browser can find the WPAD server by typing into the browser:.Test to see if Webmonitor is serving the wpad.dat script by typing into the browser: ( Note: Substitute WebMon_IP_Address with the actual IP address of the WebMonitor Server).Open the IE browser (uncheck all proxy settings so that the browser does not cache the script).To troubleshoot the ability of a client machine (in a subnet on your network) to resolve the WPAD script use these steps:.All browsers support DNS however, so adding a DNS alias record is preferred Many browsers (such as Firefox) only support NetBIOS and DNS.However, many organizations block NetBIOS broadcasts across routers, so if the client machine is on the other side of one of these routers it may not be able to resolve the host (unless it can use the other options) The Webmonitor server broadcasts that it is the WPAD host using NetBIOS.Internet Explorer will use the following order to determine the host: The difficulty comes when trying to find a host called WPAD.Once it finds the IP address of the host named 'WPAD', it uses http to request the document called wpad.dat Note: In order to connect to the machine must first find a host on the network called 'WPAD' and resolve its IP address.Each web browser can do this differently.When a web browser has its proxy setting set to 'Automatically Detect Settings', the WPAD protocol is used to find a web server that will serve up a configuration script called wpad.dat.Note: Do not use BOTH Automatically Detect AND 'Use a proxy server for this LAN' - The browser will try WPAD first and when that fails, it will use the 'Use proxy server' setting and will not be able to get out to the internet when a user is outside of the local network.In these cases it is better to use 'Automatically Detect Settings' which should discover the proxy server when on the local network, and when on a different network it will not detect the proxy server, resulting in use of the default gateway If the latter setting is used and the computer is a laptop that goes home with the user, the user will have problems getting to the internet (because the computer will be sending the http traffic to the IP Address and port specified). When setting proxy settings, there is an option to use 'Automatically Detect Settings' or 'Use a proxy server for your LAN' - IP & Port.Test if a client is going through the GFI WebMonitor Proxy by connecting to from a client machine.Additional notes and techniques which can assist in further troubleshooting WPAD related problems:
