Microsoft distributes SQL Server 2000 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2000 fix release.
When a client program runs a query against a Microsoft SQL Server Service Pack 3 (SP3) database, the query may take longer than usual. You may notice this behavior when you do the following:
You run a query on the SQL Server database by using SQL Query Analyzer while the client program is connected to the database.
You restart the instance of SQL Server while SQL Query Analyzer is still open.
Additionally, you may notice a message that is similar to the following in the SQL Server error log even when the shared memory network library is turned on:
2003-02-19 19:26:10.12 server SQL server listening on TCP, Named Pipes.
The earlier message indicates that SQL Server is not using the shared memory network library.
You may also notice the following error message in the Windows event log of the computer that is running SQL Server:
Note When you close SQL Query Analyzer, you may notice that the response time of the query run from the client program returns to normal

To work around this problem, turn off the shared memory protocol on the computer that is running SQL Server Service Pack 3 (SP3). To do this, follow these steps.
Note Turning off shared memory protocol may cause performance degradation of the computer that is running SQL Server.
Click Start, point to Programs, point to Microsoft SQL Server, and then click Client Network Utility.
In the SQL Server Client Network Utility dialog box, click the General tab.
Click to clear the Enable shared memory protocol check box, and then click OK.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
The problem may affect the performance of applications including the services and Web applications that run on the computer that is running SQL Server SP3. However, working around this problem by turning off shared memory protocol can cause performance degradation on the computer. This behavior occurs because the shared memory network library uses a location in the computer's memory that does not require network or disk access. When you use a network-based protocol such as TCP/IP, the computer uses more memory.
