I'm currently running an instance of MSDE SP3 on Windows Server 2003. Only one instance is running and it's the default instance. I verified the method of installation and am trying to upgrade to SP 4 by running the file sql01P.msp. However, when I run it I get a message that the current SA password is blank and to set BLANKSAPWD=1 to ignore this vulnerability. I'm not a DBA so I don't know how to do this off the top of my head. I searched for documentation but haven't found anything of any help. Please provide guidance for this. Also, because of the application that's using it the SA password has to be blank, so please don't recommend configuring a password for this. Thank you.
