After the organization I work for recently implemented an ISA proxy, we began noticing that websites implementing Java applets could no longer work on our Windows 7 computers. After several attempts of installing/uninstalling Java, the problem persists. The strange thing is that the Windows XP computers can access these websites without any problem. In XP, a Java window pops up requesting for username/domain/password information, and entering in this information correctly will load the website OK. No such window pops up in Windows 7. Has anyone experienced this and/or knows of a way to resolve this? Our current workaround is installing Windows XP Mode on our Windows 7 systems.

Hi Leo, Thanks for the information - however the steps described above do not work. Please note that this is not an IE-specific problem. None of the browsers we have tried (Mozilla, Chrome, IE) have been able to work. My thinking is that this is a Windows 7 issue because everything works OK in Windows XP.

Hi, Since Java is not the product of Microsoft, and I’m not very familiar with Java, I just give you some generally steps to troubleshoot the issue. You’d better ask Java Forum for further help: http://www.java.com/en/download/help/index.xml Please Note: Since the website is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information. Thank you for your understanding.

Hi wexes, Please kindly to try these tests: 1 Login with Safe Mode with networking to see if the same issue occurs. 2 Temporarily bypass ISA proxy 3 Add a credential in “Credential Manager” in Windows 7 Hope that helps.

Hi Leo, Thanks for your advise. However, after following steps 1 and 3, the problem persists. I bypassed the ISA proxy by connecting directly to the internet and the sites affected worked OK. Connect back to the proxy and the same error occurs.

Hello, I am having the same exact issue with a windows 7 machine. We also use an ISA proxy and configured both the browser (IE) and the Java Client to pass thru that proxy but the connection is still originating as the machines IP and not the proxy. I installed the microsoft firewall client (2004) to force all connections thru the proxy and it works, but breaks other services. I have tried IE8, Firefox, and chrome with no success. Does anyone know of a fix for this?
