Bug #: 469407 (SQL Server 8.0)



''Microsoft distributes Microsoft 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.''



SUMMARY
This article describes the following about this hotfix release:
 * The issues that are fixed by this hotfix package
 * The prerequisites for installing the hotfix package
 * Whether you must restart your computer after you install the hotfix package
 * Whether the hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes
 * The files that are contained in the hotfix package



SYMPTOMS
When you try to access a SQL Server 2000 database from an application, you may receive an error message that is similar to the following:

Microsoft OLE DB Provider for ODBC Drivers error '80004005'

[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]General network error. Check your network documentation.

You experience this problem when the application is performing a long-running cursor fetch. When that cursor fetch is canceled or causes a query timeout, you receive the error message. Also, an error message that is similar to the following is written to the SQL Server 2000 error log:

spid304 Stack Signature for the dump is 0x6759BDE6

spid304 SQL Server Assertion: File: , line=3260 Failed Assertion = 'm_cILockBytesOpen == 0'.

spid304 Error: 3624, Severity: 20, State: 1.

spid304 clean_tables_xact: active sdes for tabid 69357750920

Note After the assertion occurs that causes the SQL Server service to shut down unexpectedly, you may also experience random access violation error messages.
