Change Password for SQL Server User by David Weber






Most security experts' recommendations include changing passwords frequently to enhance security. It is easy to change the password on a SQL Server Username via Query Analyzer. Changing the password with Query Analyzer makes it easy to coordinate changing the password on the database server at the same time as it is changed in the connection string. This approach provides the flexibility to change the password at the most appropriate time for the application.

To change the SQL Server Username password, just connect to the database with Query Analyzer using the SQL Server Username that is being updated and the current password. Then run "sp_password" to change the password.

sp_password [ [ @old = ] 'old_password' , ]
{ [ @new =] 'new_password' }
[ , [ @loginame = ] 'login' ]

The Office Microsoft Documentation for sp_password

Here is a simple example that changes the current password from
"currentPSWD" to "newPSWD";

sp_password 'currentPSWD', 'newPSWD'

Be sure to use a strong password, "newPSWD" is just an example. I always like to test any change like this right away. For a quick test to confirm that the new password is working, close Query Analyzer and then re-connect with the new password. That is all there is to it, except for changing your connections string. It is obvious, but still critical to remember to change the password in your connection string if this SQL Username is used in your code. Once the password has been changed and tested with Query Analyzer, update the connection string with the new password and test that e verything still works correctly, and you're done.

hi, i am new to SQL server 2005. whenever i tried to
create database through SQL sever Management studio, it asked me:

server type: (here i select Database Engine)
server Name : ( ??????????)
Authentication : (Windows Authentiction is by default, another is SQL
server Authentication, which one should i select?????????)...


username:


password:


username & p/w acivated only when i select SQL server authentication.


i don't know what to do with server name .


if i entered Administrator (which is my computer's name), it gives
following error:


cannot connect to Administrator


An error has occured while establishing a connection to the server. When
conencting to SQL servr 2005, this failure may be caused by the fact
that under the default settings SQL server does not allow remote
connections. (provider: Named Pipes Provider, error: 40 - could not
open a connection to SQL server) (Microsoft SQL server err: 123)


i had also tried MSSQLSERVER which is default server name, ".", "LOCAL" as suggested, but same error occurs.

i don't know what to do with server name . plsssssssssssssss help me
