FIX: Invalid TDS Sent to SQL Server Results in Access Violation (818897)

SYMPTOMS

SQL Server may become unresponsive to existing and new connections. When you open the error log, you might find the following exception access violation:

2003-04-10 02:57:55.16 spid77    SqlDumpExceptionHandler: Process 77 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process..
* *******************************************************************************
*
* BEGIN STACK DUMP:
*   04/10/03 02:57:55 spid 77
*
*   Exception Address = 00686FEA (TProcessRPCParams<3,0,0>::ProcessParams + 000027E4 Line 0+00000000)
*   Exception Code    = c0000005 EXCEPTION_ACCESS_VIOLATION
*   Access Violation occurred writing address 77D30000

Immediately following this call stack, you might also find the error recorded by the same SPID as the exception:

2003-04-10 02:57:59.66 spid77 Error: 17805, Severity: 20, State: 3
2003-04-10 02:57:59.66 spid77 Invalid buffer received from client..

These errors might be followed by a series of other errors in the error log, if SQL Server continues to run.

You might also find this Message 17805

Invalid buffer received from client

by itself, without an access violation.
