7z Cracker, useful tool

I am very like 7zip Application among many of zip application because of easy to use, support many zip file format and handy.

Sometime I need to zip and protected it with password by using 7zip for some important files.

One day, I've forgot the password to unlock one of my important files.

Then I seek application to unlock it and found out 7z Cracker as the best.

It's really useful to crack your password protected files within few seconds even you give complex password.

If you would like to try it or need urgently to unlock for your password protected files, you can download it from below link.

http://sourceforge.net/projects/sevenzcracker/

But you also need to download 7za Application to work your 7z Cracker. Your pre-installed 7z application will not work for this and so download it from below link.

You can reference Read Me file  for "How to use"  that include inside the 7z Cracker Application when you downloaded.


But please take note this is for educational and personal usage purpose only.

Using this for illegal is at your own risk.

Solving "The name of the security certificate is invalid" error

We purchase SSL Certificate to get secure when we use Outlook Web Access with Exchange Server.

We use the External Domain URL for OWA when we purchase SSL Certificate.

But the issue can come out when your Internal URL and External URL of Exchange Server are different.

The issue is user will get security alert pop-up when he/she open outlook client everytime.



To get rid of this issue, we need to change the Internal URL of OWA on Server.

Let's start.

First, run the Exchange Management Powershell as Administrator.

"Use Get-ClientAccessServer | FL" command to collect existing configuration for revert back if something goes wrong.



Next, use "Set-ClientAccessServer -Identity CAS_Server_Name -AutodiscoverServiceInternalUrl https://mail.ictformyanmar.com/autodiscover/autodiscover.xml" command and change the URL accordingly.

Only High-lighted text are need to aware as yours.

After that, go to Exchange IIS Manager and select Application Pools. Then right click on MSExchangeAutodiscoverAppPool and click Recycle.



Fine. We are done!

You can re-check by using Get-ClietAccessServer | FL command to ensure changed URL.

If everything is fine, just close and open the outlook client at user's PC and you won't see any secrutiy pop-up regarding Certificate.

I've use ClientAccess service only on my Server.If you use  WebServicesVirtualDirectory, OABVirtualDirectory and UMVirtualDirectory, you also need to change the URL for these too.

My server is  Microsoft Exchange Server 2007. Powershell command is different and depends on Server Version. So, do not forget to reference Microsoft Powershell Technet Website.
