We have been seeing and trying to resolve SQL connectivity issue all the time. I guess it would be helpful if we can put some guidance on how to resolve connectivity issues.

Here comes a proposal based on my experience. Basically, when you failed to connect to your SQL Server, the issue could be: 1) Network issue, 2) SQL Server configuration issue. 3) Firewall issue, 4) Client driver issue, 5) Application configuration issue. 6) Authentication and logon issue.

Usually, customers see connectivity issue in their applications, but it would be great if you can follow the steps below to eliminate issues one by one and post a question on forum if needed. Step 1: Network issue You might be able to make local connection without a working network, but that's a special case. For remote connection, a stable network is required.

The first thing to trouble shoot SQL connectivity issues is to make sure the network we rely on is workable and stable. Please run the following commands: ping -a (use -4 and -6 for IPv4 and IPv6 specifically) ping -a nslookup (type your local and remote machine name and IP address multiple times) Be careful to see any mismatch on the returned results. If you are not able to ping your target machine, it has high chance that either the network is broken or the target machine is not running. It's possible the target machine is behind a firewall and the firewall blocks the packets sent by ping, though. Windows firewall does not block ping (ECHO) packet by default. The correctness of DNS configuration on the network is vital to SQL connection. Wrong DNS entry could cause of all sorts of connectivity issue later.

See this link for example,. Step 2: SQL Server configuration issue You need to make sure the target SQL Server is running and is listening on appropriate protocols.

You can use SQL Server Configuration Manager (SCM) to enable protocols on the server machine. SQL Server supports Shared Memory, Named Pipes, and TCP protocols (and VIA which needs special hardware and is rarely used). For remote connection, NP and/or TCP protocols must be enabled. Once you enabled protocols in SCM, please make sure restart the SQL Server. You can open errorlog file to see if the server is successfully listening on any of the protocol.

The location of errorlog file is usually under:%ProgramFile%Microsoft SQL Server/MSSQLxx.xxx/MSSQL/Log If the target SQL instance is a named instance, you also need to make sure SQL Browser is running on the target machine. Www stream pirates 2 revenge 2008 full download mp4. If you are not able to access the remote SQL Server, please ask your admin to make sure all these happen.

Step 3: Firewall issue A firewall on the SQL Server machine (or anywhere between client and server) could block SQL connection request. An easy way to isolate if this is a firewall issue is to turn off firewall for a short time if you can. Long term solution is to put exception for SQL Server and SQL Browser.

For NP protocol, please make sure file sharing is in firewall exception list. Both file sharing and NP use SMB protocol underneath. For TCP protocol, you need put the TCP port on which the SQL Server listens on into exception. For SQL Browser, please put UDP port 1434 into exception. Meanwhile, you can put sqlservr.exe and sqlbrowser.exe into exception as well, but this is not recommended. IPSec between machines that we are not trusted could also block some packets. Note that firewall should never be an issue for local connections.

Step 4: Client driver issue At this stage, you can test your connection using some tools. The tests need to be done on client machine for sure.

First try: telnet You should be able to telnet to the SQL server TCP port if TCP is enabled. Otherwise, go back to check steps 1-3. Then, use OSQL, SQLCMD, and SQL Management Studio to test sql connections. If you don't have those tools, please download SQL Express from Microsoft and you can get those tools for free. OSQL (the one shipped with SQL Server 2000) uses MDAC. OSQL (the one shipped with SQL Server 2005 & 2008) uses SNAC ODBC. SQLCMD (shipped with SQL Server 2005 & 2008) uses SNAC OLEDB.

SQL Management Studio (shipped with SQL Server 2005 & 2008) uses SQLClient. Possilbe command use be: osql -E -SYour_target_machineYour_instance for Windows Auth osql -Uyour_user -SYour_target_machineYour_instance for SQL Auth SQLCMD also applies here. In addition, you can use “-Stcp:Your_target_machine, Tcp_port” for TCP, “-Snp:Your_target_machineYour_instance” for NP, and “-Slpc:Your_target_machineYour_instance” for Shared Memory.

You would know if it fails for all protocols or just some specific procotols. At this stage, you should not see general error message such as error 26 and error 40 anymore. If you are using NP and you still see error 40 (Named Pipes Provider: Could not open a connection to SQL Server), please try the following steps: a) Open a file share on your server machine. B) Run “net view ” and “net use ” (You can try Map Network Drive from Windows Explorer as well) If you get failure in b), it's very likely you have OS/Network configuration issue, which is not SQL Server specific. Please search on internet to resolve this issue first. You can try connection using both Windows Authentication and SQL Authentication. If the tests with all tools failed, there is a good chance that steps 1-3 were not set correctly, unless the failure is logon-related then you can look at step 6.

If you succeeds with some of the tools, but fails with other tools, it's probably a driver issue. You can post a question on our forum and give us the details. You can also use “ windowssystem32odbcad32.exe” (which ships with Windows) to test connection by adding new DSN for various drivers, but that's for ODBC only. Step 5: Application issue If you succeed with steps 1-4 but still see failure in your application, it's likely a configuration issue in your application. Think about couple of possible issues here. A) Is your application running under the same account with the account you did tests in step 4?

If not, you might want to try testing in step 4 under that account or change to a workable service account for your application if possible. B) Which SQL driver does your app use? C) What's your connection string?

Is the connection string compatible to your driver? Please check for reference. Step 6: Authentication and logon issue This is probably the most difficult part for sql connectivity issues. It's often related to the configuration on your network, your OS and your SQL Server database. There is no simple solution for this, and we have to solve it case by case.

There are already several blogs in sql_protocols talking about some special cases and you can check them see if any of them applies to your case. Apart from that, things to keep in mind: a) If you use SQL auth, mixed authentication must be enabled. Check this page for reference b) Make sure your login account has access permission on the database you used during login ('Initial Catalog' in OLEDB). C) Check the eventlog on your system see if there is more information At last, please post question on our. More people could help you over there. When you post question, you can refer to this link and indicate you see failure at which step. The most important things for us to troubleshoot are a) exact error message and b) connection string.

Teamspeak 3 Error Failed To Connect To Server

Any ideas why? Please help to find the solution to problem.

Failed To Connect To Computer

We used MSSQL 2000 without any problems with ODBC, and now we tried to use MSSQL2008. Approximately on every fifth PC we cannot set the ODBC connection with SQL server, we receive error logs: SQL State ‘1000’ SQL Server error 10060 SQL State ‘08001’ SQL server error 17 we tried everything, it seems that on some clients something missing, but I have no idea what is this. The clients MSSQL ODBC version: with this version on one PC it is working, on the pother isn’t. I tried to turn of the firewall: no effect. SandorVigh, error 10060 is: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. This still looks like a firewall issue if the server name is correct.

Did you tried to follow my steps to troubleshoot? Is your server machine Vista/Windows Server 2008? Turning off the firewall on Vista/W2k8 is little tricky as it involves different domains. I would suggest you post your follow up question on our forum (mentioned at the end of the blog) Thanks, Xinwei. Hi I am getting an error: 'Message:[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified '. Just to brief about my setup, It goes like this;I have a SQL server 2008 installed on Win 2008 (x64)and I also have a clinet machine installed with Win 2003(32-bit). Now I am trying to establish a connectivity between them by using SNAC tool (v10.0).

Actually I am running one benchmark application script on Client machine which first tries to establish the database connectivity. Now I think some one can give me some clue what could be the reason for the error.I also have created Aliases on both server as well as Client machine (Was not very sure where they required to be created). I have been strugling all alone for quite a time now.Hope someone can help me to reach at the solution.

Thanks & Regards, SM. Hi I am getting an error: '[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied' While accessing SQL Server 7.0 from a MS Access 2007 application.

Smtp Error: Failed To Connect To Server: (0)

Thank you, -Larry. Thank You so much Keik. You helped determine the last port I had to unblock. I am running SQL 2008 on WS 2008.

For anyone else having this issue for me I did this. On my Windows Server 2008 I did the following: 1.Added an exception for the SQL Browser exe file. 2.Added an exception for the UDP Port 1434. 3.Found out what the listening port was by following Keik’s advice which is 'Look in the registry using regedit.exe at HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL ServerSQLEXPRESSMSSQLServerSuperSocketNetLibTcp. One of the nameValue pairs has name TcpPort and a value, which is the port that the SQL Server is listening on (mine was set to 1030).' Mine was 51070 then added the exception to that tcp in the windows firewall.

Then boom all access finally granted. Thank you Keik for suggesting that as it finally became unblocked and now works like a champ. I have spent litterally 2 days getting this to work and I had figured that it was a simple firewall issue but was lost on where to find the information. God Bless you Sir! I installed sql server 2005 (dev) I have a java program which takes connection from database connection string is: 'jdbc:sqlserver://localhost:1434;databaseName=abc' when i ru this iit works fine. I modified the code now it takes connection and with out closing it tries to take another connection second time it throws an exception msg saying:: 'An I/O error occurred while receiving the TDS prelogin response.'

I thought its because of maximum no of connection but maximum no of conn is set to 0(ulimited). Please help mee. Looks like you are trying to use Trusted_Connection. Is the application running on IIS or some other mid-tier application server? Using Trusted_Connection will utility the authentication of the process. So, if the process is configured to run as 'SERVERGUEST' then, that’s the user credential SQL Server Native Client will use. If the application is hosted in IIS, please make sure IIS is configured to support Windows Authentication (WS.10).aspx BTW, for these type of troubleshooting questions, I recommend posting the question on our forum where you have the entire community to help you.

HTH, Jimmy Wu. I am having problem running the sqlcmd command in my linux box with an error 'Unable to load SQLCMD resource file(s)'. After investigating this I realized that the driver and sqlcmd are looking for the resource files at a specific path /opt/microsoft/msodbcsql location.

In my environment this is not possible: 1) I am not an admin and can not access to that directory 2) We use enterprise file system so individual machine installation directory is not allowed. Is it possible to have the driver look at some other location for resource files? Please let me know, since this is stopping me from going forward. I am not able to connect to SQL 2005 DB in windows authentication,plz help me outi'm gtng an error as follows.
