When a service or an application quickly and repeatedly connects to and disconnects from a local Microsoft SQL Server 2000 database, a handle leak may occur in the SQL Server process.
These leaks only occur in the SQL Server 2000 Service Pack 2 (SP2) version of the shared memory network library (Dbmslpcn.dll version 2000.80.534.0).
The handle leaks occur in two locations. The handle leak occurs in the first location because of a missing DeleteCriticalSection function call when a connection is closed. The handle leak occurs in the second location because of event handles that are created repeatedly during the connection process.

NOTE: The security patches described in Microsoft Security Bulletins MS02-039, MS02-043, MS02-056 and the original release of the security patch described in MS02-061 (released on October 16, 2002) do not contain the Q317748.exe patch discussed in this knowledge base article. This patch was subsequently discovered to be required to ensure normal operation of SQL Server.
If you have applied any of these security patches and decide to apply the patch from this Knowledge Base article you must answer "no" if prompted to overwrite files to ensure that you do not overwrite files from the security patch.
The re-released security patch for Microsoft Security Bulletin MS02-061 (released on January 26, 2003) includes this fix, and if you have installed this re-released patch, no action is required. The re-released patch is available from the following article in the Microsoft Knowledge Base:
(http://support.microsoft.com/kb/316333/EN-US/ )INF: SQL Server 2000 Security Update for Service Pack 2
