Cannot Connect To Sql Server 2008 R2 Express Remotely
if you are trying to connect to a SQL Server named instance. For default instance, you never see this. Why? Because even if we failed at this stage (i.e. error locating server/instance specified), we will continue to try cannot connect to local sql server 2008 connect using default values, e.g defaul TCP port 1433, default pipe name for Named Pipes. You may see other error message due to failure later, but not this error message. Every time client makes a connection to SQL Server named instance, we will send a SSRP UDP packet to the server machine UDP port 1434. We need this step to know configuration information of the SQL instance, e.g., protocols enabled, TCP port, pipe name etc. Without these cannot connect to local sql server 2008 r2 login failed information, client does know how to connect the server and it fails with this specified error message. In a word, the reason that we get this error message is the client stack could not receive SSRP response UDP packet from SQL Browser. It's easy to isolate the issue. Here are the steps:1) Make sure your server name is correct, e.g., no typo on the name. 2) Make sure your instance name is correct and there is actually such an instance on your target machine. [Update: Some application converts \ to . If you are not sure about your application, please try both ServerInstance and Server\Instance in your connection string]3) Make sure the server machineis reachable, e.g, DNS can be resolve correctly, you are able to ping the server (not always true). 4) Make sure SQL Browser service is running on the server.5) If firewall is enabled on the server, you need to put sqlbrowser.exe and/or UDP port 1434 into exception.

Windows Firewall is configured to allow inbound TCP & UDP 1433, 1434. Windows Firewall is configured to allow outbound TCP & UDP on any port. No other software AV/FW is currently running. When I try to connect to xxx.xxx.xxx.xxx\sqlexpress, it times out with the following error: TITLE: Connect to Server http://stackoverflow.com/questions/6466974/unable-to-connect-to-sql-express-error-26-error-locating-server-instance-speci Cannot connect to xxx.xxx.xxx.xxx\SQLEXPRESS. ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=-1&LinkId=20476 BUTTONS: OK I have checked that remote connections are allowed on the server. I have confirmed TCP/IP is enabled and configured in SQL Server Configuration to allow connections on the external IP to 1433. I have also used Wireshark from my local machine and I can see requests for 1433 UDP going to the remote server. But using Wireshark on the remote server shows no inbound connection requests for 1433 UDP or anything from my external IP (with filtering to remote RDP from results). This makes me think it is a firewall issue. The server is hosted by an external company who have control over the PIX in front of our server. I need to troubleshoot this as much as possible myself as the hosting company have no clue what they are doing. sql sql-server sql-server-2008 sql-server-express-2008 share|improve this question edited Jun 7
