SNA Server 3.0 SP1 Update May Break Named Pipe ClientsLast reviewed: March 19, 1998Article ID: Q167196 |
The information in this article applies to:
SYMPTOMSAfter you apply SNA Server 3.0 Service Pack 1, named pipe clients may be unable to get sponsor connections to the computer running SNA Server. When you start the SnaBase service on an SNA Server Windows NT 3.x client configured to use Microsoft Networking (Named Pipes), the following error message appears:
SNA Server - Error # 1003 SNABase Could Not open Sponsor Connection To Server <servername>.This problem does not occur if the sponsor connection is configured to a SNA Server 3.0 Server (Service Pack 1 not applied) or if TCP/IP is selected in the "Select Client/Server Protocol for Client Setup" dialog box on the client. NOTE: This error message can appear for other reasons as well.
CAUSEThe SNA Server 3.0 Service Pack 1 update program updates the NullSessionPipes registry value, but fails to correctly add null- termination to the end of the last entry:
HKEY_LOCAL_MACHINE\System\ CurrentControlSet\Services\LanmanServer\Parameters\ NullSessionPipes:REG_MULTI_SZ: COMNAP COMNODE SQL\QUERY SPOOLSS LLSRPC EPMAPPER LOCATOR COMPROXY COMNETMThe last character of the last entry has been truncated, and is missing the terminating carriage return.
RESOLUTIONTo work around this problem: WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.
STATUSMicrosoft has confirmed this to be a problem in SNA Server 3.0 SP1. This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
