java.net.ConnecException: Connection timed out:connect

Starting last Monday I have had several users who access a website to process payroll get java.net errors. They login to the website and work fine but when they try to run some processes they get
Java.net.connectexception: Connection timed out: Connect
I have posted the entire error as an attachment. The users are going through an ISA 2006/Windows 2003 firewall but I see no denies in the logs. I also created a rule to give them full access through. The clients are running Windows XP Pro with Java 6.0.110. (Which is required by the web application)

The JRE settings,...unfortuneately,...are at the user-level,...not the machine level so this has to be repeated in each user profile,...but run the Java Control Panel Icon,...set the proxy settings in the Networking section to "direct",...so you run it as if the proxy never existed. Then install the Firewall Client on the machines. It the communication through the ISA is "anonymous" you can skip the Firewall Client,...but if it requires authentication then the FWC is a requirement. The JRE, throughout its "life" from version to version, has sometimes had problems dealing with a CERN Compliant Web Proxy Service that requires authentication and the ISA Web Proxy is CERN Compliant. Configuring the JRE as I described removes the Web Proxy Service from the equation and allows it to operate over a "winsock proxy service" (which the ISA Firewall Service is) when authentication is required,...or let it operate over SecureNAT if communication is anonymous.

Thanks for the reply....

I do have the 'Direct ' selected in the Network Settings. I am new to ISA. Your comment on "It the communication through the ISA is "anonymous" you can skip the Firewall Client" , How do you configure this?

I do believe I have SecureNAT configured. I have opened a case with MS to help resolve this.

Still doesn't make any sense to me. Why would this just all of a sudden start happen. No changes were made to the firewall. No java updates were performed on the client.

Do you and your users have automatic updates from Microsoft turned on? That can screw up your environments suddenly, with, say, a new security release.
