INF: Listening on Multi-Protocol Fails on Startup

ID: Q160871

The information in this article applies to:

Microsoft SQL Server version 6.5

SUMMARY

When a computer running SQL Server is configured to listen only on the multi-protocol network protocol, the MSSQLServer service may fail on the startup of Windows NT Server. This problem may occur when Windows NT Server is starting and the remote procedure call (RPC) service has not completed initializing before SQL Server starts the server-side RPC Net-Library. You will find the following errors in the SQL Server errorlog:

Using 'SSMSRP60.DLL' version '6.5.0.0' to listen on ''.
Error : 17826, Severity: 18, State: 0

Unable to set up ListenOn connection ''.
OS Error : 1899, The endpoint mapper database could not be created.
conn_hdlr: Unable to initialize Communication Layer

MORE INFORMATION

Configure the computer running SQL Server to listen on either another network protocol or another protocol in addition to multi-protocol.

One other way to resolve this problem is to modify the Windows NT Server registry to force the MSSQLServer service to depend on the RPC service, requiring that the RPC service be initialized before MSSQLServer service attempts to start.

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.

Start the Registry Editor (Regedt32.exe) and navigate to the following key:


      HKEY_LOCAL_MACHINE\system\CurrentControlSet\Services\MSSQLServer

Click the MSSQLServer subkey. On the Edit menu, click Add Value.

Enter the following:


      Value Name: DependOnService
      Data Type:  REG_MULTI_SZ
      Data:       RpcSs

Click OK and quit Registry Editor.

Shut down and restart the computer running Windows NT Server.
