Answer 1

If you do not have create on sql the session database you need first to run a tool to create it using the aspnet_regsql.exe tool.

DATABASENAME = AnyNameOfServerState
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>aspnet_regsql.exe -ssadd -sstype c -d DATABASENAME -E

More for this tool: http://msdn.microsoft.com/en-us/library/ms229862(VS.80).aspx

Second you can connect using Integrated security and not use user name and password. Set this on connection strings

<add name="SqlState" connectionString="Data Source=localhost;DataBase=AnyNameOfServerState;Integrated Security=True" providerName="System.Data.SqlClient"/>

This go to system.web

<sessionState mode="SQLServer" sqlConnectionString="SqlState" allowCustomSqlDatabase="true" cookieless="false" timeout="20"/>

Some more details. If you go to your net directory you see a list of files with .sql extention. One of this is the InstallSqlState.sql, this is the one that the tool runs to create the database. If you open it you can see what is run.

You can also use a StateServer. You can following the step-by-step guide here

I hope you know the pro/cons of each of the session states so you can choose the right one for your application.
