Cannot connect to an instance of SQL Server 2008
I am trying to connect to a SQL Server 2008 server instance via NHibernate using C#. I am unable to do so.
I have been successful in connecting to to the same instance via Hibernate using java. So i am kinda sure that there is nothing wrong with my SQL Server 2008 configuration settings. I have also managed to connect to SQL Server 2008 Express.
Here is the hibernate.cfg.xml
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
<property name="connection.connection_string">server=(local)SUNIL,3067;Initial Catalog=NHibernate101;User ID=sunil;Password=mypassword;</property>
<property name="show_sql">true</property>
<property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property>
<property name="cache.use_query_cache">false</property>
<property name="adonet.batch_size">100</property>
<property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
<mapping assembly="Infrastructure" />
</session-factory>
</hibernate-configuration>
Here is the error message:
Test method NHibernate101.Tests.RepositoriesTest.CanCreatePost threw exception: System.Data.SqlClient.SqlException: Login failed for user 'sunil'.
Here is the stack trace:

The error message seems pretty obvious:
System.Data.SqlClient.SqlException: Login failed for user 'sunil' .
That would indicate that the user specified in the connection string
So I would try to fix your connection string to make sure you can log in:
server=(local)SUNIL,3067;Initial Catalog=NHibernate101;
User ID=sunil;Password=mypassword;
SUNIL
and resides on your local machine? NHibernate101
? sunil
exist on that server? mypassword
? sunil
exist in NHibernate101
? Can you connect to that server, that database, with exactly that login and password, from SQL Server Management Studio??
