NHibernate sessions don't support nested transactions.

The following test is always true in version 2.1.2:

var session = sessionFactory.Open();
var tx1 = session.BeginTransaction();
var tx2  = session.BeginTransaction();
Assert.AreEqual(tx1, tx2);

You need to wrap it in a TransactionScope to support nested transactions.

MSDTC must be enabled or you will get error:

{"Network access for Distributed Transaction Manager (MSDTC) has been disabled. Please enable DTC for network access in the security configuration for MSDTC using the Component Services Administrative tool."}
