2. If the Java program operates correctly, the problem is probably specific to one Web site. Follow the steps in the "Java Problems on One Web Site" section in this article. If neither of the Java programs operate correctly, the problem is most likely specific to all Web sites. Follow the steps in the "Java Problems on All Web Sites" section in this article.

Java problems on one Web site

If you cannot view a Web site that contains Java programs, but can view other Web sites that contain Java programs, follow these steps to resolve the issue:

1. Click Start, click Run, type control inetcpl.cpl, and then click OK.
2. For Internet Explorer 3.x, on the Advanced tab, click to clear the Enable Java JIT Compiler check box, and then click OK. For Internet Explorer 4.x, 5.x, and 6, on the Advanced tab, click to clear the JIT Compiler for virtual machine enabled (requires restart) check box, and then click OK.
3. Restart Internet Explorer, visit the Web site that exhibited the problem, and then test to determine whether the issue has been resolved.

Java Problems on All Web Sites

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
If you cannot view any Web site that contains Java programs, follow these steps to resolve the issue.

Note This issue may occur if an old version of the NetZip program is installed on your computer and it is configured to start automatically when you start your computer. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

1. Click Start, click Run, type control inetcpl.cpl, and then click OK.
2. For Internet Explorer 4.x, 5.x, or 6.x, on the Security tab, verify that the Disable Java option is not enabled for the Web content zone in which you are having problems with Java applets.
   
   Note This option is available only with the Custom option in Internet Explorer 4.x and 5.x. Java is not disabled if you have selected High, Medium, or Low security in Internet Explorer 4.x and 5.x. In Internet Explorer 6, Java is disabled by default with a security level of High, and Disable Java is also available as a custom option.
   
   If the Disable Java option is not enabled, or if the Java add-ins that are in the Web content zone are not working, select another safety level for Java, and then follow the steps in the "Determining the Scope of the Java Problem" section to determine whether the issue has been resolved. If the problem still occurs, go to step 4.
