SYMPTOMS
Consider the following scenario.
 * You create a Web project that is built on the .NET Framework 2.0.
 * You run a long-running stored procedure or an SQL script inside an externally initiated transaction in the Web project.
 * After the procedure runs for a long time, the thread is killed because the execution time exceeds the value of the ExecutionTimeout setting on the server.

In this scenario, you cannot manipulate the data table that is used in the transaction. This condition is true until the connection to the database is reset.

Note The connection to the database can be reset only if the database is located on the Web server. If the database is located on the Web server, the database can be reset in about 2.5 minutes.
