To do so, there is a online tool you can use and it is free – http://validator.w3.org/checklink/

Just type your domain at the text box and click “Check” button. If your site got broken links, it will show in the result like below:

Wifi Issue – Connected but still no Internet access

If you face the above issue, this could be due to DCHP Client services was stopped or disabled. To check on this in Window 7,

1. Go to Start > Control Panel > System and Security > Administrative Tools.
2. Double-click “Services”.
3. Find “DHCP Client”
4. If it was disabled, right click and go to “Properties”
5. Change the “Startup Type” to “Manual”
6. Click the “Start” button.
7. * You may need to do the same for “DNS Client” services.

Invalid jdkhome specified – Cannot locate java installation in specified jdkhome:

You click the NetBeans IDE shortcut and got a message like below:

This is due NetBeans cannot locate java installation in specified jdkhome: C:\Program Files\Java\jdk1.6.0_22
Most probably you initially installed JDK at the default location above and then you uninstall it and reinstall to another location.

Anyway, to fix this, all you need to do is just go to find netbeans.conf from where you installed your NetBeans. For me, I have it at C:\Program Files\NetBeans 6.9.1\etc

Once found, open the file and look for something like below:

netbeans_jdkhome=”C:\Program Files\Java\jdk1.6.0_22″

Then, change the above to the valid path, example

netbeans_jdkhome=”C:\Java\jdk1.6.0_22″

That’s it!
