SchemaExport para o Sql Server 2005

Pessoal,

O persistence.xml:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
	version="1.0">
	<persistence-unit name="TestEJB">
		<jta-data-source>java:/DefaultDS</jta-data-source>
		
		<mapping-file>META-INF/orm.xml</mapping-file>
		
		<properties>
			<property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>
			<property name="hibernate.hbm2ddl.auto" value="create-drop" />
		</properties>
    	
	</persistence-unit>
</persistence>  

O DataSource

<?xml version="1.0" encoding="UTF-8"?>
<datasources>
  <local-tx-datasource>
  <jndi-name>DefaultDS</jndi-name>
  <connection-url>jdbc:sqlserver://localhost:1433;DatabaseName=DB_Test</connection-url>
  <driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class>
  <user-name>sa</user-name>
  <password>senha</password>
  <check-valid-connection-sql>SELECT 1 FROM sysobjects</check-valid-connection-sql>
  <metadata>
	  <type-mapping>MS SQLSERVER2000</type-mapping>
  </metadata>
  </local-tx-datasource>
</datasources> 	

Não está gerando as tabelas, alguém tem alguma idéia?

Tenta deixar update ao invés de create-drop e altera o type-mapping para 2005.
