NHibernate connection problem

I am using sql server 2005

but having error message on _sessionFactory = configuration.BuildSessionFactory();

What is wrong and how can I correct it?

My Hibernate.cfg.xml

 <property name="connection.driver_class">NHibernate.Connection.DriverConnectionProvider</property>
<property name="dialect">NHibernate.Dialect.MsSql2000Dialect</property>
<!--<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>-->
<property name="connection.connection_string">Server=localhost\SQLServer2005;database=NHibernate101;Integrated Security=True;</property>
<property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
<mapping assembly="Infrastructure"></mapping>

and my in my web.config

    <connectionStrings>
    <add name="ApplicationServices" connectionString="Server=localhost\SQLServer2005;database=NHibernate101;" providerName="NHibernate.Connection.DriverConnectionProvider"/>
</connectionStrings>

Error message is:

You're receiving that error because in your Hibernate.cfg.xml you're telling NHibernate to use the NHibernate.Connection.DriverConnectionProvider class for connection.driver_class property. The connection.driver_class property is expecting an IDriver interface while the NHibernate.Connection.DriverConnectionProvider is not.

Your configuration is incorrect. Use this one:

<property name="hibernate.connection.provider">NHibernate.Connection.DriverConnectionProvider</property> 
<property name="hibernate.connection.driver_class">NHibernate.Driver.SqlServerCeDriver</property> 
<property name="dialect">NHibernate.Dialect.MsSql2000Dialect</property> 
<property name="connection.connection_string">Server=localhost\SQLServer2005;database=NHibernate101;Integrated Security=True;</property> 
<property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property> 
<mapping assembly="Infrastructure"></mapping>

Could it be the fact that you've specified the SQL2000 dialect rather than the 2005 one? I've never had that happen so I'm not sure if it would raise this error.
