The tool only needs to be run one time, so customers who have previously run it do not need to take additional action. By sending a specially formatted request to UDP 1434 port, it could be possible to overrun the buffers associated with either of the functions. This activity could consume most or all of the available bandwidth on the two machines. Unlike the DBCCs discussed in MS02-038, the one affected by this variant could be executed by any SQL user.

What is a stored procedure? A stored procedure is a precompiled collection of Transact-SQL statements stored under a name and processed as a group. Customers who are seeking the patch for MS02-040 should instead apply the patch from MS03-033. Best practices recommends against both of these practices. Exploiting this vulnerability would allow the attacker to escalate privileges to the level of the SQL Server service account. More hints

This documentation is archived and is not being maintained.

I thought that the SQL Server 2000 patch in Microsoft Security Bulletin MS02-039 corrected the vulnerability being exploited by the "slammer" virus. It is possible to create a keep-alive packet that, when sent to the Resolution Service, will cause SQL Server 2000 to respond with the same information. What vulnerabilities does this patch eliminate? This is a cumulative patch that, when applied, address all previously addressed vulnerabilities. Knowledge Base articles can be found on the Microsoft Online Support web site.

However, this patch has been superseded by the patch released with MS02-061 which contains fixes for additional security vulnerabilities in these products. Code Red Worm This would consume resources on both systems, slowing performance considerably.
