I got complaint from my user about their Thunderbird email client spell check function. According to them, the spell check function stop working. I tried to do misspelled two word in this email client to demonstrate the problem. I found that the email client fail to detect the wrong spelling.

To perform troubleshooting on this problem, i try to check on Thunderbird Options setting by using bellow steps .

From the pop-up dialogue shows an empty grey box for “Language” which means that Dictionaries & Language Packs installed on that computer. To solve the spell check issue, just need to manually install Dictionaries & Language Packs.

Below are the steps:-

• Click Add to Thunderbird.
• Wait for the download to finish; even if nothing seems to be happening, chances are a dialog will eventually appear.
• Click Install Now under Install add-ons only from authors whom you trust..
• Now click Restart Now.

Done!!

Recently i successfully setup OpenVPN server. It try to connect from my Windows XP pc, it work fine. But when i connect the OpenVPN via my Windows 7 and Windows Vista machine, it fail to connect.

The error they were getting was:

Thu Sep 16 13:30:09 2011 C:\WINDOWS\system32\route.exe ADD 172.16.0.0 MASK 255.255.0.0 10.8.0.1
Thu Sep 16 13:30:09 2011 ROUTE: route addition failed using CreateIpForwardEntry: Access is denied.   [status=5 if_index=24]
Thu Sep 16 13:30:09 2011 Route addition via IPAPI failed [adaptive]
Thu Sep 16 13:30:09 2011 Route addition fallback to route.exe
Thu Sep 16 13:30:09 2011 ERROR: Windows route add command failed [adaptive]: returned error code 1

To solve above problem, just edit the config file of the SSL vpn (the .ovpn file) in C:\Program Files\OpenVpn\config and add the following lines:

route-method exe
route-delay 2

This will force OpenVPN to add the route using Route.exe

After that , find the OpenVPN GUI icon on your desktop, right-click on it, and choose Properties from the context menu. In the Properties window, click “Advanced…” then check “Run as administrator”. Click OK to close the “Advanced Properties” window and click OK to close the OpenVPN GUI Properties window.

Your DNS cache stores the locations (IP addresses) of pages you have recently viewed. DNS cache help to speeds up the lookups within the same host.  But sometimes if the website page change before your DNS cache is updated, you will failed to access the page. For example, you received a web page with HTML 404 error codes. So you need to flush your DNS cache. Once you clear your DNS cache, your computer will query nameservers for the new DNS information you require.

Clear DNS cache on Windows XP, Vista, Win7

1. Open the Start menu.
2. Go to Run.
   • If you do not see the Run command in Vista, search for “run” in the Search bar.
3. In the Run text box, type: ipconfig /flushdns
4. Press Enter or Return, and your cache will be flushed.

To clear DNS cache in Mac OS X 10.5 and above, use the following command:

1. Go to Applications.
2. Go to Utilities.
3. Open the Terminal application.
4. Type: dscacheutil -flushcache
5. Press Enter or Return, and your cache will be flushed.

Shutdown is a very useful command that can help your daily administrative task. This program allows you to restart or shutdown your local or remote computers.

To access shutdown command, simply go to DOS command prompt by clicking on Start -> All Programs -> Accessories -> Command Prompt or Start -> Run and then type in cmd to launch a command prompt window.

Below are the few example on how to use Shutdown command:-

To reboot the computer:

shutdown -r

To restart  computer immediately:

shutdown -r /t 0

Note: T0 restart immediately, use the /t 0 option. The /t 0 option ensures that a time-out period of 0 (zero) seconds is used before the command is executed. /t can be set between 0 and 600 seconds (0 and 10 minutes). 

To shutdown a computer:

shutdown -s

Note: By default there is a 30 second delay with all SHUTDOWN commands, this at least gives you a short window to use the abort command to stop a shutdown if you’ve made a typing mistake. 

To abort/cancel shutdown:

shutdown -a

To shutdown computer immediately:

shutdown /p

To shutdown Remote computer immediately:

shutdown /m \\remotecomputername /s /t 0

To Hibernate computer:

The following command will execute a hibernation directive and will within 30 seconds begin a hibernation and shutdown action:

shutdown /h

Just try it, have fun
