7、ver 2000. This article contains descriptions of common connectivity problems and the steps that you can take to help resolve your connectivity problems. SQL Server 2000 supports several methods of communication between the instance of SQL Server and the client applications. If your client applicatio
8、n and the instance of SQL Server reside on the same computer, Microsoft Windows interprocess communication (IPC) components, such as local named pipes or the Shared Memory protocol, are used to communicate. However, when the client application and the instance of SQL Server reside on different compu
9、ters, a network IPC, such as TCP/IP or named pipes, is used to communicate.SQL Server 2000 uses Net-Library, a DLL, to communicate with a particular network protocol. A matching pair of Net-Libraries must be active on the client computer and the server computer to support the network protocol that y
10、ou want to use. For example, if you want to enable a client application to communicate with a specific instance of SQL Server across TCP/IP, the client TCP/IP Sockets Net-Library (Dbnetlib.dll) must be configured to connect to the server on the client computer. Likewise, the server TCP/IP Sockets Ne
11、t-Library (Ssnetlib.dll) must listen on the server computer. In this scenario, the TCP/IP protocol stack must be installed on both the client computer and the server computer.After you install SQL Server 2000, you can configure the properties of the client Net-Libraries by using Client Network Utili
12、ty. You can configure the properties of the server Net-Libraries by using Server Network Utility (Svrnetcn.exe). The server Net-Libraries are installed during the installation of the server tools in SQL Server Setup. However, some of the server Net-Libraries may not be active. By default, SQL Server
13、 2000 enables and listens on TCP/IP, named pipes, and Shared Memory. Therefore, for a client to connect to a server computer, the client must connect by using a client Net-Library that matches one of the server Net-Libraries that is currently being used by the instance of SQL Server.For additional i
14、nformation about SQL Server communication components and Net-Libraries, see the following topics in SQL Server Books Online: Communication ComponentsClient and Server Net-LibrariesManaging ClientsTroubleshoot connectivity issuesMost of the connectivity issues that you may notice in SQL Server 2000 o
15、ccur because of problems with TCP/IP, Windows authentication, or a combination of TCP/IP and Windows authentication. Important Before you start to troubleshoot connectivity issues in SQL Server 2000, make sure that the MSSQLServer service is started on the computer that is running SQL Server.Verify
16、your DNS settingsThe name resolution process in Domain Name System (DNS) is used to resolve the IP address to the name of the instance of SQL Server. If the name resolution process does not work correctly, the instance of SQL Server is not reachable, and you may receive one or more of the following
17、error messages: SQL Server does not exist or access deniedGeneral Network ErrorCannot Generate SSPI ContextTo verify that the name resolution process is resolving the correct server, you can ping the server by using the server name and the IP address of the server. To do so, follow these steps: 1.Cl
18、ick Start, and then click Run.2.In the Run dialog box, type cmd in the Open box, and then click OK.3.At the command prompt, run the following command:ping Note the IP address that is returned.4.At the command prompt, run the following command (where IP address is the IP address that you noted in ste
19、p 3):ping a Verify that the command resolves to the correct server name. If either of the specified commands are not successful, time out, or do not return the correct values, the DNS lookup is not working correctly or the problem occurs because of other networking or routing issues. To see your cur
20、rent DNS settings, run the following command at a command prompt:ipconfig /allTo work around this problem, add an entry for the server to the %systemroot%system32driversetchosts file on the client computer. You can also work around the problem by connecting to the server by using the Named Pipes Net
21、-library.Verify the enabled protocols and aliasesConnectivity problems may occur if the alias on the client computer is set incorrectly. You can view the aliases by using Client Network Utility. To do so, follow these steps: 1.Start Client Network Utility. If the SQL Server client tools are installe
22、d on the computer that is running the client application, follow these steps to start Client Network Utility: a. Click Start, and then point to Programs.b. Point to Microsoft SQL Server, and then click Client Network Utility.If the SQL Server client tools are not installed on the client computer, fo
23、llow these steps to start Client Network Utility: a. Click Start, and then click Run.b. In the Run dialog box, type cliconfg in the Open box, and then click OK.2.In the SQL Server Client Network Utility window, click the General tab, and then enable all the protocols that you want to use.Note You mu
24、st at least enable the TCP/IP protocol and the named pipes protocol.3.Click the Alias tab, and then verify the aliases that are configured for the instance of SQL Server. 4.Verify the properties of the aliases to make sure that the server name or IP address and the protocol are configured correctly.
25、You can create a new alias to test the connectivity by using the server name, the IP address, or even by using a different protocol.Note Earlier versions of Microsoft Data Access Components (MDAC) have a different user interface for Client Network Utility. Therefore, if you do not see the options th
26、at are listed in this article, install a later version of MDAC on the computer that is running the client application.Verify that the instance of SQL Server is listening correctlyTo verify that the instance of SQL Server is listening on named pipes, TCP/IP, or another protocol that you are using at
27、the client application, open the current SQL Server error log file. The SQL Server error log file may contain entries that are similar to the following:2003-11-06 09:49:36.17 server SQL server listening on TCP, Shared Memory, Named Pipes. 2003-11-06 09:49:36.17 server SQL server listening on 192.168
28、.1.5:1433, 127.0.0.1:1433.If you analyze the entries in the SQL Server error log file, you can verify that the instance of SQL Server is listening on the correct IP address and on the correct port. By default, a default instance of SQL Server listens on the port 1433. You can also use Server Network
29、 Utility to verify the protocol settings for SQL Server and to change the properties in SQL Server, including the protocols that can connect to SQL Server and the ports that can be used. For more information about using Server Network Utility, see the SQL Server Network Utility topic in SQL Server B
30、ooks Online. Sometimes, SQL Server 2000 may not bind to port 1433 or any other specified port. This problem may occur if the port is being used by another application or if you are trying to connect by using an IP address that is not correct. Therefore, the TCP/IP connections to SQL Server may not b
31、e successful and you may receive the following error message in the SQL Server error log file: 2001-11-14 15:49:14.12 server SuperSocket Info: Bind failed on TCP port 1433.If you cannot connect to the instance of SQL Server by using a TCP/IP connection, try to use the named pipes protocol or the Sha
32、red Memory protocol. Run the following command at a command prompt to obtain information about the ports that are in use:NETSTAT anYou can also use the Portqry command-line utility to obtain more information about the ports that are in use.Note For named instances of SQL Server, SQL Server dynamical
33、ly determines the port and listens on the determined port. Therefore, when you start the named instance of SQL Server, SQL Server tries to listen on the port that was previously being used. If SQL Server cannot bind to that port, the named instance may dynamically bind to a different port. In that s
34、ituation, make sure that the client application is also set to determine the port dynamically. Alternatively, you can also specify a static port for the named instance to bind to and to listen on by using Client Network Utility.Troubleshoot MDAC IssuesConnectivity problems may also occur because of
35、problems with MDAC. For example, a software installation may overwrite some of the MDAC files or change the permissions that you must have to access the MDAC files. You can run the MDAC Component Checker to verify the MDAC installation on your computer.Note If you are connecting to a named instance
36、of SQL Server, make sure that you are running MDAC 2.6 or later on your computer. Earlier versions of MDAC do not recognize named instances of SQL Server. Therefore, connections to named instances may not be successful.You can use the Odbcping.exe utility to verify connections through the SQL Server
37、 ODBC driver.You can also test connectivity to the instance of SQL Server by using a .udl file.Troubleshoot firewall issuesIf firewall exists between the client computer and the computer that is running SQL Server, make sure that the ports that are required to communicate through the firewall are op
38、en.If you use the TCP/IP protocol to connect to the instance of SQL Server, make sure that you can use the Telnet program to connect to the port where SQL Server is listening. To use the Telnet program, run the following command at a command prompt: Telnet If the Telnet program is not successful and
39、 you receive an error message, resolve the error and then try to connect again.Note Because of issues that were caused by the Slammer virus, the User Datagram Protocol (UDP) port 1434 may be blocked on your firewall.Troubleshoot authentication and security issuesConnections to SQL Server may not be
40、successful because of authentication failures. If the authentication fails, you may receive one of the following error messages:Login failed for user Login failed for user NTAUTHORITYANONYMOUS LOGONLogin failed for user nullIf you receive an error message because of an authentication failure and the
41、 error message does not mention a specific SQL Server login name, troubleshoot the problem with Windows authentication. You may receive the following error message because of problems with Windows authentication: Cannot generate SSPI ContextThe following problems may cause authentication and securit
42、y issues: Problems occur with NTLM authentication or with Kerberos authentication.The domain controller cannot be contacted because of connectivity issues.Problems occur with trust relationships across domains.For more information about possible causes, see the event logs on the computer. To work ar
43、ound connectivity problems with Windows authentication, you can use SQL Server Authentication to connect to the instance of SQL Server. If the connection is not successful when you use SQL Server Authentication, you receive the following error message: Login failed for user . Not associated with a t
44、rusted connectionTo troubleshoot this problem, follow these steps. Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor inc
45、orrectly. Use Registry Editor at your own risk. 1.Make sure that the instance of SQL Server is configured to use Windows authentication and SQL Server Authentication. To do so, make sure that the following registry keys are on the computer that is running SQL Server. For the default instance of SQL
46、Server: HKEY_LOCAL_MACHINESoftwareMicrosoftMSSQLServerMSSQLServerLoginModeFor the named instance of SQL Server: HKEY_LOCAL_MACHINESoftwareMicrosoftMicrosoft SQL ServerMSSQLServerLoginModeMake sure that the following registry key values are set:Authentication typeValueWindows authentication only1Mixe
47、d mode (SQL Server Authentication and Windows authentication)2Note If you make any changes to the registry, you must stop and then restart the instance of SQL Server for the changes to take effect.2.Try to connect to the instance of SQL Server by using different Windows accounts or SQL Server login accounts. This can help det
