The information in this article applies to:

  • Microsoft SQL Server, version 4.21a

BUG# NT: 10665 (4.21a)

SYMPTOMS

Remote Stored Procedure calls (RPC) from Sybase SQL Server versions 4.8 and 4.92 on UNIX platforms to Microsoft SQL Server via TCP/IP may fail with the following error message: 

   Message 7223: Can not read from site '%.*s'
This failure may occur when remotely executing any stored procedures, such as sp_who.

CAUSE

The server-side network library for TCP/IP (SSMSOCN.DLL) incorrectly handles the RPC requests from certain versions of Sybase SQL Server on the UNIX platforms.

WORKAROUND

Replace the server-side network library SSMSSOCN.DLL with version 4.21 (dated 1/26/94). If you experience any out-of-band data problems (such as invalid buffer errors on the client)after switching to the older version, you may avoid them by adding the following entry to the NT 3.5 registry: 

   System\CurrentControlSet\Services\Tcpip\Parameters\TcpUseRFC1122Urgent
   Pointer = 0x1

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 4.21a. This problem was corrected in the latest U.S. Service Pack for SQL Server version 4.21a. For information on obtaining the Service Pack, please contact your primary support provider.
