Got 2 Windows XP client machines. They are trying to connect to a web page with a java applet requiring authentication (appears to be built into the applet).
If I have the firewall client installed on each PC they can authenticate successfully, but if I remove or disable the firewall client, the applet times out after entering the credentials.
The reason I want to get this working without the firewall client is because I am using Nortel Contivity VPN Client on the machines. This works without the firewall client, but when installed, stops working.
I'm sure you can see my dilemma here. I can't have the VPN Client and the java applet working properly at the same time. Any help would be greatly appreciated.

William,
It sounds like once the firewall client is disabled that the java applet is unable to connect to the remote site because it is not working with the web proxy. I'm going to assume for now that the authentication is actually http-auth which establishes permissions prior to downloading the applet.
The first thing I would check is the network settings of the applet viewer by going through Control Panel -> Java. Here you should see that the proxy is either set to use browser settings (assuming they point to the web proxy) or that the appropriate values have been explicitly stated.
You should also bring up the Java Console and set debugging level to the maximum (should be 5). This will at least give you some indication as to where it is all going wrong. If the proxy is causing a problem you will soon see an exception caused by a failure to complete the HTTP request after you enter the authentication details.
I have, in the past, had to give up on using the web proxy when trying to access an applet because it would not recognise or authenticate to the proxy. In this case I would set the applet host address to bypass the proxy and add a 'Site and Content Rule' to the Access Policy that allows Everyone access to the destination set containing the host address. This was almost an act of desperation but fulfilled the requirement at the time.
