I was able to connect to MSSQL 2008 express on local machine using SQL server management Studio for host 'nash-pc\sqlexpress'. But when I connect with Microsoft JDBC driver it gives me error like below. JDBC has problem with having '\' in the host name? I'm not sure how to make host name to become 'localhost' instead of 'nash-pc\sqlexpress'. funny thing is that if i use server name as 'localhost' then I could not even connect with SQL server management Studio.
"The driver encountered an unknown error: com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host nash-pc, port 1433 has failed. Error: "Connection refused: connect. Verify the connection properties, check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port, and that no firewall is blocking TCP connections to the port."."
My JDBC connection string
Driver: com.microsoft.sqlserver.jdbc.SQLServerDriver
url: jdbc:sqlserver://nash-pc\sqlexpress:1433;databaseName=jruby

I have a SQL Server setup on one machine, where I have created a user and assigned a database to the user.
Now I want to access that server from client machine using management studio.
What I did:
I enabled remote access from Management Studio on the server machine from server properties and set authentication mode as "Windows auth and SQL Server auth"
I set TCP port as "1433" for IPAll in SQL Server Network Configuration and restarted SQL Server Services
I created an inbound rule in firewall settings to accept all connections on port "1433"
I added port forwarding in my router settings as follows: Router Port Forwarding
(That's my private IP address in destination address)
I types public IP (49.36.55.132\SQLEXPRESS) in client machine SQL Server Management Studio along with username and password with SQL Server authentication mode.
Getting this error on client machine:
Cannot connect to 49.36.55.132\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)
Check out your port forwarding on your Server machine, you should add your port on your modem.
change your port, 1433 is default port.so you need to have Dynamic Port for you service.
First you have to completely disable firewall in server machine and check if client machine sees server. After that if it's ok, check connecting with sql server management studio from client and at last enable firewall with rules to check if error is from firewall port settings.
I'm having a hell of a hard time trying to figure out why I can connect to my SQL Server using Management Studio using my local ip or local computer name or sql instance name but I can't connect to the same SQL Server using my public ip address.
I have tried all of the below steps but nothing seems to fix the Wait Operation Timed Out error message:
Disabled firewall on the SQL Server and the computer I'm trying to use to connect with.
Port forwarding is enabled for the port I'm using which is the default 1433
Ran the telnet command: telnet publicip port from a computer outside of my network and it was successful
Restarted the SQL Server plenty of times
Enabled remote connections for the server and enabled tcp/ip for the 1433 port
I also enabled port forwarding for the sql browser service using the recommended port of 1434 via udp
Tried to connect with named instance but only works with local ip and not public ip
I am pretty much out of ideas at this point so any help is greatly appreciated
Here is the full error message just in case anyone needs to see it:
Cannot connect to XX.XX.XXX.XXX,1433.

My database and my web application are at the same server at the moment and I would like to access SQL Server as localhost and close the SQL Server port for remote connections.
This is my current connection string, how can I modify it so it will access the database from as localhost?
"ConnectionStrings": {
"DefaultConnection": "Server=tcp:152.242.211.112;Initial Catalog=testdb;User ID=usera;Password=********"
}
I tried:
server=(local)
tcp=127.0.0.1
Data Source=(local)
using Data Source=(local)\\SQLEXPRESS
I got this message:
A connection was successfully established with the server, but then an
error occurred during the login process. (provider: Shared Memory
Provider, error: 0 - No process is on the other end of the pipe.)
SQL Server uses the magic string (local) instead of localhost - this is because SQL Sever can use transports other than TCP/IP for connecting to the server instance (like Named Pipes and Shared Memory) whereas the hostname localhost is specific to TCP/IP.
So use Data Source=(local);Initial Catalog=... in your connecting string.
I've tried enabling TCP/IP - setting tcp port - restarting sql service - creating firewall inbound rule for the port - allowing remote connections on sql server - I'm able to ping - server name: tcp:, with correct credentials - server name: , and still not working.
What am I missing?
Error I'm getting:
Cannot connect to <server name>
ADDITIONAL INFORMATION:

If you are not setting the domain users then make sure you are using SQL Server authentication and either set up local user in the database or simply use the sa user (not recommended)
Because you are not specifying the SQL Server edition, please take a look this link for enabling remote access if you are using SQL Server 2005
I'm installing an application and getting following error:
Can't connect to SQL Server DB.
Error: The TCP/IP connection to the host , port 1433 has failed.
Error: : Connection timed out. Verify the connection properties.
Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connection at the port.
Make sure that TCP connections to the port are not blocked by a firewall.
Can someone please advise me?
