>MICROSOFT SQL SERVER VERSION 7.0 FIX
>Microsoft has identified a potential problem you may experience with SQL
>version 7.0. Under rare conditions a malformed Tabular Data Stream (TDS)
>packet, which is submitted using Remote Procedure Call (RPC) protocol, can
>cause various Access Violations (AVs). The AV may result in a server
>shutdown if it occurs within the Open Data Services (ODS) layer. If
>occurring outside ODS, the AV may cause instability that results in a server
>The cause of the malformed packet is usually a network-layer factor such as
>the Network Interface Card (NIC), NIC device driver, or network router. Much
>less frequently a bug in the ODBC, OLE-DB, or DB-Library client libraries
>may cause the problem.
>This hot fix improves the server-side robustness for handling these
>malformed packets. In some situations (but not all), it will avoid the AV.
>Instead you may see error 17805: "Invalid buffer received from client."
>A supported fix that corrects this problem is now available from Microsoft,
>but it has not been fully regression tested and should be applied only to
>systems experiencing this specific problem. If this specific problem does
>not severely affect you, Microsoft recommends that you wait for the next SQL
>Server Service Pack containing this fix.
>To resolve this problem immediately, contact Microsoft Product Support
>Services to obtain the fix. For a complete list of Microsoft Product Support
>Services phone numbers and information on support costs, go to the following
>Q246612 - FIX: Malformed RPC TDS Packet Causes Various AVs
>P.S. for anyone using a Windows NT system and experiencing 'Access
>Violations' this might be something to check into.
