Again a guess. I think you have <depends optional-attribute-name="ConnectionManager">jboss.jca:service=DataSourceBinding,name=TEST</depends> in your mssql-jdbc2-service.xml. Change it to <depends optional-attribute-name="ConnectionManager">jboss.jca:service=DataSourceBinding,name=MSSQL2000XADS</depends> In short, i think you are using TEST(which is your database name) in most of configuration files when you should actually be using the jndi-name of the datasource (MSSQL2000XADS).
