SQL SERVER offers two login mechanisms: windows account login and database user login. The former login is to log on with windows system Administrator account, the latter is to log on with user account set up in the SQL Server – the typical one is SA account.

If you can log on to the server by windows admin account, it is not difficult to solve the problem.

• 1. Login into SQL server using Windows Authentication.
• 2. In Object Explorer, open Security folder, open Logins folder. Right Click on SA account and go to Properties.
• 3. Reset SA password, and confirm it. Click OK to finish.
• 4. After restarting SQL Server and all its services, you can log into SQL Server by SA login with new SQL SA password.

If you cannot go through the above steps, try following ways.

Method 1

MS SQL Server Password Unlcoker grantees 100% successful SA password reset for MS SQL Server 2008/2005/2000 in seconds. You only need to have master.mdf file of the server.

1. Download MS SQL Server Password Unlocker on your local PC, install and launch it.

2. Click the Open button to import the file of master.mdf.

3.Select the SA account and then click Change Password button.

4. Enter your new password and click OK.

5. Login to SQL Server to see if you have reset SA password.

Method 2

If you have no system administrator privileges, as long as can get two files like *.mdf (data file) and *.ldf of the database (log file), you can also access to SQL Server through below operations.

Assume that the data file and the log file are sy. mdf and sy. ldf, copy them in d: \. (Please stop SQL Server service at first and then copy the files.) And the database name is “newsy”.

First, install a new SQL Server on your computer, log on to open Query Analyzer, and then enter the SQL statement: sp_attach_db ‘newsy’,'d:\sy.mdf’,'d:\sy.ldf’

Then press F5 key, if the system prompts “command completed successfully”. Congratulations, you get the full control of that database.

Compared with method 1, method 2 is hard and complicated, a tool works to reset SA password is more time-saving. You can download trial version of MS SQL Server Password Unlcoker for evaluation.

Rar Password Setting

In previous post, we have talked about how to set RAR password quickly by using a new profile. Now we will learn how to encrypt RAR archive with default password by setting default compression option.

1.      Open a RAR file, click Options in menu bar, and then Select settings…

2.      In the pop-up window, click Create default… button.

3.      In Set default compression options, select Advanced tab, and then Set password. Ok and save the profile.

4.      Thus every time when you need to compress and encrypt a file, you only have to compress it, since the default profile has encrypted the file, which saving your time greatly.

Caution: Remember that password carefully, since RAR encryption has become one of the most secure encryption methods, all your RAR archives could not be opened again without RAR password recovery tools.

RAR Password Recovery

Password Unlocker Studio commits itself to password recovery and reset, and develops the latest 4.3 version of RAR Password Unlocker. It has greatly improved RAR password recovery speed by applying CPU-acceleration and GPU acceleration for RAR archives encrypted by WinRAR 4.01 anԁ its previous versions.

That is to say, if your CPU has multiple cores, the software will make use of all cores to quicken password recovery process.

What’s more, it implements RAR password recovery via 3 attack ways: Brute-force, Brute-force with user-defined Mask and Dictionary.

Even if you forgot RAR password, you may still remember its components, such as length, uppercase, lowercase, numbers, symbols, prefix and suffix, set these in Brute-force with Mask attacks. The more you set, the more cracking time will be saved.

Unlike other programs, its interface is clear and user-friendly, thus very easy to understand and operate.

Another merit you should not neglect, that is, it saves the process every 15 minutes by default. You can change the auto-save time interval by yourself. Once you pause, stop or quit, the software will automatically ask you to save the project. Therefore, no need to worry about losing password recovery process.

With your exact setting and high speed provided by RAR Password Unlocker, it is possible for you to recover RAR password in several days, or even a couple of hours. Try its demo version to evaluate.

In order to prevent the SA password from becoming stale in the future, be sure to put processes in place to change SA password on a regular basis.

Before going to recover RAR  password, you need to learn something important avout WinRAR encryption. There are provided 3 kinds of  tricks about this issue.

Trick one: A strong password

You may know that, WinRAR password recovery tools can recover all rar passwords theoretically, but in fact, as a strong password require a very long password recovery time (months or years), you still can protect your rar file securely with strong password.

A strong password should have at least eight characters that consists of uppercase and lowercase letters, numbers and symbols (@, #, $, %, etc.). It should not only include the common letters and symbols on the keyboard, but also have seldom used ones. Strong passwords also do not contain words that can be found in a dictionary or parts of the file name.

Trick two: Password in other languages

As said above, we usually set English letters in the password, have you thought that we can use other languages?

When setting rar password, try to include Japanese in the password. When rar file asks you to enter the password, you may find that you cannot enter Japanese letters. Don’t worry. Input password in a txt file and then copy it to the password box.

Most WinRAR password recovery tools cannot recover password like that. So take care of the password; once you forget it, just give up the attempts to reopen it.

Trick three: Encrypt insignificant file with the target file

When WinRAR password recovery tools recover rar password, generally they work on a target file, and adopt brute force attack to guess the password.

If we compress many files together, and then give them passwords respectively, no password recovery software will be valid for it.

Specific operation as follows:

Step 1: Prepare the important file (1.xlsx) you want to encrypt in rar and insignificant file (2.xlsx).

Step 2: Compress and encrypt the insignificant file (2.xlsx). Note: Do not encrypt file names.

Step 3: Open the rar file, click Commands in file menu and choose Add files to archive.

Step 4: Add the important file (1.xlsx), and go back to Archive name and parameters.

Step 5: In Advanced tab, set a different password. Click OK, and close rar file.

You will find that, when you input password of 1.xlsx to extract the rar archive, only 1.xlsx will be extracted; when you input password of 2.xlsx, only 2.xlsx will be extracted.

You may also try to use a WinRAR or RAR  password recovery tool to retrieve its password. The result is that it will only find password for 2.xlsx, and the password of important file (1.xlsx) cannot be recovered.

In this way, the data of 1.xlsx is securely protected.

SQL Server operates in one of two authentication modes: Windows Authentication Mode (the default) or Mixed Mode (Windows Authentication and SQL Server Authentication). SQL Server Authentication is provided for backward compatibility, because applications written for SQL Server version 7.0 or earlier may require the use of SQL Server logins and passwords. Even though Windows Authentication is recommended, SQL Server Authentication may be required for connections with clients, and also be necessary for legacy applications.

Change default Windows Authentication Mode to Mixed Mode

Method 1: During installation, an option named SECURITYMODE can be used to change the default login authentication mode to SQL server authentication mode.

Method 2: This can be easily changed in security tab after the installation.

Step 1 Open SQL, right-click the name of SQL Server, and then choose properties.

Step 2 The following picture will come up, select SQL server and Windows authentication mode in security tab. Finish.

Method 3: Another way to change the security mode after installation is to stop SQL Server and set the appropriate registry key for your installation:
Default instance:

HKLM\Software\Microsoft\MSSqlserver\MSSqlServer\LoginMode

Named instance:

HKLM\Software\Microsoft\Microsoft SQL Server\Instance Name\MSSQLServer\LoginMode

to 0 or 2 for mixed-mode or 1 for integrated. (Integrated is the default setup for the SQL Server 2000 Data Engine.)
When you change the default login authentication mode into SQL authentication, we recommend you set a strong SA password.

Reset SA password in SQL 2008/2005/2000

Change SA password as follows:

• 1. In Object Explorer, open Security folder, open Logins folder. Right Click on SA account and go to Properties.
• 2. Type a new SQL SA password, and confirm it. Click OK to finish.

If you forgot SA password, and what’s worse, you disabled Windows authentication mode due to security consideration, how to get a password to login?

Import master.mdf in SQL Server installation folder to MS SQL Password Unlocker which will list all login names, reset SA password, then you can login with the new password immediately, no matter how long and complex the old password is. Vey easy, isn’t it?

More information about SA password:

According to Microsoft, System administrator (SA) is a special login provided for backward compatibility. By default, it is assigned to the sysadmin fixed server role and cannot be changed. Although it is a built-in administrator login, SA does not be used routinely. Instead, make system administrators members of the sysadmin to be fixed server role, and have them log on using their own logins. Use SA only when there is no other way to log in to an instance of Microsoft SQL Server.
