NHibernate有时候会出现连接不上数据库

出错:NHibernate.ADOException: cannot open connection ---> System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) ---> System.ComponentModel.Win32Exception: 拒绝访问。

NHibernate各种数据库连接参数文件配置方法说明
//配置文件Config/Hibernate.cfg.xml内容如下所示：
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory name="CwfServer">
<property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
<property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property>
<property name="connection.connection_string">server=192.168.1.244;database=wf_db_t;uid=sa;pwd=supersit.1;</property>
<property name="adonet.batch_size">10</property>
<property name="show_sql">true</property>
<property name="command_timeout">60</property>
<property name="hbm2ddl.auto">update</property>
<property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>
<!--<property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>-->
<mapping assembly="Net.NHibernateDB"/>
<mapping assembly="Cwfapi"/>
<mapping assembly="CwfEngine"/>
</session-factory>
</hibernate-configuration>
