SUMMARY
This article describes how to troubleshoot problems with Java. The following topics are discussed:
 * Determining the scope of the Java problem
 * Java problems on one Web site
 * Java problems on all Web sites



Determining the scope of the Java problem
To determine the scope of the Java problem, follow these steps:  Visit the following MSN Java Web site:

http://zone.msn.com/bejeweled

 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:

195762 Problems viewing Java programs with NetZip installed

 Click Start, click Run, type control inetcpl.cpl, and then click OK. 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. Change the display settings to a lower resolution and fewer colors. To do so, follow these steps:  Click Start, point to Settings, click Control Panel, and then double-click Display.</li> On the Settings tab, click 16 Colors in the Color Palette box, and then move the Desktop Area slider to the far left (640 By 480 Pixels).</li> Click OK.</li> Follow the steps in the "Determining the Scope of the Java Problem" section in this article to determine if the issue has been resolved. If the issue has been resolved, notify the video adapter manufacturer of the problem and request a video adapter driver update. If the issue has not been resolved, go to step 4.</li></ol> </li> Change the display settings to 800 by 600 resolution and 256 colors. To do so, follow these steps:  Click Start, click Run, type control desk.cpl, and then click OK.</li> On the Settings tab, click 256 colors for color, and then move the slider to 800 by 600 pixels.</li> Click OK.</li> Quit System Configuration Editor. If you are prompted to save any files, do so.</li> Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Step By Step Confirmation from the Startup menu.</li> When you are prompted to process the Config.sys and Autoexec.bat files, press N. When you are prompted to load all Windows drivers, press Y, and then hold down the SHIFT key while Windows starts to prevent items in the Startup group from being processed.</li> Follow the steps in the "Determining the Scope of the Java Problem" section in this article to determine if the issue has been resolved. If the issue has been resolved, continue with step 6. If the issue has not been resolved, skip to step 7.</li></ol> </li> Perform a clean boot for your operating system and then follow the steps in the "Determining the Scope of the Java Problem" section in this article to determine if the issue has been resolved. If the issue has been resolved, continue with step 6. If the issue has not been resolved, skip to step 7. For additional information on performing a clean boot, click the following article numbers to view the articles in the Microsoft Knowledge Base:

281770 How to perform clean-boot troubleshooting for Windows 2000

267288 How to perform a clean boot in Windows Millennium Edition

192926 How to perform clean-boot troubleshooting for Windows 98

243039 How to perform a clean boot in Windows 95

</li> Isolate any conflicts with terminate-and-stay-resident programs (TSRs) or real-mode device drivers. To do so, restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Step By Step Confirmation from the Startup menu. Press N for every TSR or real-mode device driver. When Windows restarts, follow the steps in the "Determining the Scope of the Java Problem" section in this article to determine if the issue has been resolved. If the issue has not been resolved, continue with step 7.</li> <li>If you connect to the Internet using a local area network (LAN), contact your network system administrator and verify that you have access to Java programs through the network firewall.</li></ol>

If these steps do not resolve the issue, please contact Microsoft Product Support Services.
