I'm having a heck of a time getting a MS SQL datasource connected through my railo installation. I can connect fine through Adobe ColdFusion, but railo keeps throwing an error
In Adobe ColdFusion I have my server set as mycomputername\sqlexpress and port 1433. In Railo using the same server, database, username and password. I'm getting the following error
The TCP/IP connection to the host myservername, 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."..
I've also tried connecting via the IP address listed in SQL Server Configuration Manager IP4 is set to active and enabled with an IP address of 127.0.0.1 but that throws the same error as above
I have IPv6 turned on and that shows up as IP1 in my TCP/IP settings, but I don't know why that would be causing an issue.
Port 1433 is open as I can connect through Adobe ColdFusion. I hope I'm missing something obvious, but I'm stumped.
I finally got this working by changing the Listen All setting to no in SQL Server Configuration Manager > TCP/IP Propertiest
and setting the TCP Port to 1433 and enabling the datasource in IP2 below

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.
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: TCP Provider, error: 0 - The wait operation timed out.) (Microsoft SQL Server, Error: 258)
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?
Issue resolved with the help of SQL Server configuration Manager
I have a Windows Server 2008 R2 running SQL Server 2012 Standard Edition and:
Allow remote connection to this server (in SQL Server Management Studio)
TCP/IP Enable and configured IPserver and 1433 port (on SQL Server Network Condiguration -> Protocol for...)
Named Pipes Enable (on SQL Server Network Condiguration -> Protocol for...)
Shared Memory Enable (on SQL Server Network Condiguration -> Protocol for...)
Firewall Off
When I run telnet localhost 1433 on the server - connect perfect. But if I run telnet IPSserver 1433 or telnet DomainNameServer 1433 - not connect
Something else netstat -a display:
0.0.0.0:1433 NameServer:0 LISTENING
[::]:1433 NameServer:0 LISTENING
Any ideas?
You probably have the Firewall turned on, so you have to create an exception to TCP/1433.
Be aware that if you have multiple instances you must also create an exception for UDP/1434 and check on which port the multiple instances are binding.
We recently installed a sonic firewall on our network. We have a SQL 2005 express server that's configured to listen on dynamic ports. In its configuration manager the dynamic port number is set as 1067 with its default port still 1433.
From my understanding we need to have the following ports open for it to work:
Tcp 1433
Tcp 1067
Udp 1434
Problem is we still cannot connect to the server from outside. When we switch off/disconnect the firewall we can can access the server.
This tells me that the SQL server's setup is fine and the that the problem must be some port we are missing on the firewall.
Any ideas?

Client-Server Communication Over a Firewall
Setting up a client to communicate to a SQL Server over a firewall is a simple three-step process:
Make SQL Server listen on a specific port on TCP (the default is 1433) or RPC (the default is a random port greater than 1023). You have to cycle the server after this change.
Configure your firewall server to allow traffic on the specific .
Make the client (on the other side of firewall) use the appropriate connection string to talk to the on the server. You can also use the Client Configuration Utility to add an "Advanced" entry with the appropriate Net-Library and connection string.
