SA is the administrative login for the MSSQL. To Change the MSSQL SA password please use following steps:

Step 1. Go to the command prompt of the server ( Start >> Run >> Cmd ) and type in command

osql –L

This command will list all the MSSQL servers near you.

Step 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 Server administrator account (Windows Authentication).

Step 3. To change sa password you should execute the following query:

1> sp_password NULL,’new_password’,’sa’
2> go

Here the new_password will be the password which you want to set.

Now try to login to MSSQL using new password.

Another quick way:

OSQL -S MyServer -E -Q "EXEC sp_defaultdb 'sa', 'master'"
OSQL -S MyServer -E -Q "EXEC sp_password NULL, 'NewPassword', 'sa'"
