BUG #: 56633 (SQLBUG_70)
SYMPTOMS
SQL Server provides distributed transaction capabilities through the Distributed Transaction Coordinator (DTC). When you establish a DTC transaction (ITransactionDispenser::BeginTransaction), the isolation level is specified.

The first SQL Server connection to enlist in the specified DTC transaction obtains and maintains the isolation level. However, subsequent connections, which enlist in the transaction, retain their current isolation level and do not obtain the DTC isolation level.
WORKAROUND
Immediately after enlisting in the DTC transaction, perform an explicit set operation to establish a matching isolation level for the connection and DTC transaction scope.
STATUS
Microsoft has confirmed this to be a problem in SQL Server 7.0. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server 7.0. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
