When you use a client application such as SQL Query Analyzer to start or to enlist into a distributed transaction after you have installed Microsoft SQL Server 2000 Service Pack 4 (SP4), you receive an error message that is similar to the following:
[Microsoft][ODBC SQL Server Driver][Shared Memory]ConnectionCheckForData (CheckforData()). Server: Msg 11, Level 16, State 1, Line 0 General network error. Check your network documentation.
Additionally, if you run a trace session by using SQL Profiler, you receive an error message in the trace window that is similar to the following:
Error: 8526, Severity: 16, State: 2
Note The 8526 error occurs when you implicitly or explicitly use the SAVE TRANSACTION statement to start or to enlist into a distributed transaction and the server severs the connection with the client application.
This problem occurs because the SAVE TRANSACTION statement in SQL Query Analyzer is not supported in distributed transactions that are either started with the BEGIN DISTRIBUTED TRANSACTION statement or that are escalated from a local transaction.
Note In SQL Server 2000 SP1, the undocumented trace flag 8599 was added to enable some applications to bypass the test for backward compatibility and also to make upgrading SQL Server 2000 easier. Additionally, an incorrect behavior that enabled the savepoint in a distributed transaction that did not have a trace flag was fixed in SQL Server 2000 SP4. As a result, SQL Server 2000 SP4 client applications may experience the problem that is mentioned in the Symptoms section, whereas other versions of SQL Server 2000 will not be affected.
