Cannot connect to an instance of SQL Server 2008 -

-

i trying connect sql server 2008 server instance via nhibernate using c#. unable so.

i have been successful in connecting to same instance via hibernate using java. kinda sure there nothing wrong sql server 2008 configuration settings. have managed connect sql server 2008 express.

here 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 error message:

test method nhibernate101.tests.repositoriestest.cancreatepost threw exception: system.data.sqlclient.sqlexception: login failed user 'sunil'.

here stack trace:

the error message seems pretty obvious:

system.data.sqlclient.sqlexception: login failed user 'sunil'.

that indicate user specified in connection string

  • has no permission connect server
  • has no permission connect database specified in connection string
  • a wrong password has been specified in connection string

so try fix connection string make sure can log in:

server=(local)\sunil,3067;initial catalog=nhibernate101;    user id=sunil;password=mypassword;
  • is sql server instance called sunil , resides on local machine?
  • does sql server use port 3067 ? (this not default)
  • is database called nhibernate101 ?
  • does login called sunil exist on server?
  • is login's password mypassword?
  • is user not "blocked" or locked out reason?
  • does user sunil exist in nhibernate101 ?

can connect that server, that database, that login , password, sql server management studio??
