I am installing DotNetNuke, during installation it is asking Database Password, I am giving the same password that I am using for SQL server but it is showing error.
The specified password for user account “sa” is not valid, or failed to connect to the database server
Screenshot:
You likely aren't configuring a complex enough SA password, though the Web Platform Installer won't tell you what the requirements are (likely 7 characters, with something other than just alpha)
As Daniel said, I detest the WPI and avoid it like the plague. When it works, it works great, but when it doesn't, it is really painful to troubleshoot
