Hello,

SA login is the administrative login for the MSSQL. To Change the MSSQL “SA” password you have to execute following commands from command prompt of your server:

1) Go to the command prompt of the server and type in command prompt “osql –L ”
This command will list all the MSSQL servers near you.

2) Copy full name of required MSSQL server and type

osql -S copied_servername -E

By this command you'll connect to MSSQL server using administrator account.
3) To change sa password you should execute the following query:

sp_password NULL,'new_password','sa'
go

Now try to login to MSSQL using new password.
