I have tried to remotely connect to SQL. I put in port 1433, I restarted the service, and I don't have Windows' firewall active. However, I can only use local connection, I can't remotely connect.
I read that SQL Server 2005 Express doesn't allow remote connection, but what about 2008? Does it allow remote connections?
You need to setup the server to accept tcp/ip connections.
This is done through the SQL Server Configuration Manager.
Start the manager, navigate to your server node and enable TCP/IP connections on it.

I am using Microsoft SQL Server Management Studio 17 to connect to a remote Microsoft SQL Server database. Looking at the connection dialog of Studio 17, I don't see any port number setting. Google tells me that Studio uses port 1433 by default.
I tried to use telnet to check if port 1433 is listening on the remote server: telnet example.company.com 1433
However, the connection failed. How can I find the port used for this database connection?
You could connect SSMS to your DB, run ProcessExplorer and examine the properties of ssms.exe. On the "TCP/IP" tab you possibly find what you are asking for:
Make sure you have connectivity to the server first. Since you mentioned "remote" there could be a firewall in the way, so your solution is going to depend on your network topology.
Can you ping the server? If ping works, I would reach out to the owner of the server and verify the DB connection parameters. Maybe your IP needs to be whitelisted. Etc. Etc.
Check if the server host has inbound port 1433 enabled, and whether TCP/IP is enabled using the SQL server configuration manager. If the SQL server instance in question sits on the cloud, you might want to check the specific provider's firewall rules on the container and adjust to permit 1433 inbound connections. The port setting entirely lies on where the actual SQL server instance sits. The management studio in your remote client will not be using any port.
I am trying to allow remote connections for SQL Server Express. When I connect from machine A to connect to SQL Server on machine B using Visual Studio, I get an error:
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
I followed the following steps below which did not help.
Enable remote connections on the instance of SQL Server that you want to connect to from a remote computer. Turn on the SQL Server Browser service. Configure the firewall to allow network traffic that is related to SQL Server and to the SQL Server Browser service.
In fact I tried by turning off firewalls entirely but no luck. Any suggestions ?
You need to open the SQL Server Configuration Manager and enable TCP/IP. This is not enabled by default. Port 1433 will need to be open for remote connections.

Using SQL Server 2008 R2
I have 2 SQL Server instances on my PC, SQL1 and SQL2.
I have Windows XP installed in a VirtualBox. In XP, I have an application which can connect to SQL Servers.
When I try to connect to SQL1, everything is fine, but when I try to do that with SQL2 it errors out with
Could not open a connection to SQL Server
So I started checking the settings. I can connect to SQL2 using SQL Server Management Studio (on a local PC), so I checked that 'Allow remote connections to this server' was enabled. Also, in SQL Server configuration tool I enabled all protocols for this instance, just as it is for the SQL1. SQL Server browser is working.
Configuration of both instances seem to be identical. There is only one difference between SQL1 and SQL2 that I have noticed.
SQL1 version is 10.50.4000
SQL2 version is 10.50.1600
What can cause one of the instances to be unreachable through the network while the other one can be, and both settings are the same?
It could be firewall settings or network settings. For an instance to be reachable, configure at least the following.
TCP protocol enabled (SQL Server Configuration Manager)
Fixed TCP port (SQL Server Configuration Manager)
Enable SQL Server Browser Service
Open firewall for SQL Browser service (UDP port 1434) if you have a named instance.
Open TCP ports for SQL Server Instances.

I am using MS Server 2008 with MSSQL 2008-R2 as database server.
Each time for some work i have to login to server via Remote connection.I tried to configure
the SQL Server remote connection on, followed the following steps....
1.Created Inbound and outbound rules for tcp port 1433.
2.In sqlserver configuration manager ,all is set for IP address and POrt no properties.
3.Set the SqlServer instance for remote connections.
But still its not working.
Also when i checked port 1433 for tcp on local computer it is shown closed.
thanks in advance.......
Probably port 1433 is disabled, so enable it using MS WIndows firewall.
or just use
netsh firewall set portopening protocol = TCP port = 1433 name = SQLPort mode = ENABLE scope = SUBNET profile = CURRENT
Probably MS SQL Server Browser Service is not running. So go to Services and start it.
or just execute under Run menu
%windir%\system32\services.msc
Probably TCP/IP channel is disabled under SQL Server 2008/2014 Configuration Manager. SO go there and enable all TCP/IP options.
Just in case at the same place (SQL Server 2008/2014 Configuration Manager) make sure you have 1433 port.
Make sure that SQL server is configured to allow remote connections. Use MS SQL Management Studio and right click on the top node which server itself.
In the SQL Server Configuration Manager->SQL Server Network Configuration->Protocols, check that named pipes and tcp/ip are enabled.
If that doesn't work then it may be your firewall blocking it, try this link: http://msdn.microsoft.com/en-us/library/cc646023.aspx
This may be useful too:
http://support.microsoft.com/kb/287932
If named pipes and TCP/IP access are already enabled in SQL Server Configuration Manager, then you need to either add a rule for UDP port 1434, or a rule for sqlbrowser.exe so that the SSMS client can talk to the SQL Server Browser service.
I actually see people having this problem surprisingly often so I wrote up an explanation here: http://blog.dereenigne.com/microsoft-sql-server-dynamic-ports-windows-firewall-and-you/
If you're trying to connect to an SQL Server Express instance as is my case right now... it doesn't use port 1433 by default. One must check the IpAll => TCP Dynamic Ports in Sql Server Configuration Manager. Mine is 52848.
After entering the correct port 52848 in DbSchema app (the one I'm trying to use), it connected successfully.
Check the following screenshot:
This is the way to go:
The default SQL Server express installation does not enable TCP
network protocols, so here are some steps to take to be able to
communicate with SQL Server Express. These steps should be similar for
MS SQL Server Express 2017, 2016, 2014, 2012, 2008, and 2005.
Launch the SQL Server Configuration Manager. It should be in the Start -> Programs -> Microsoft SQL Server 2005 -> Configuration Tools start menu option.
Select the SQL Server 2005 Network Configuration tab. There should be a Protocols for SQLExpress option, and one of the protocols should be TCP IP.
Enable the TCP IP protocol if it is not enabled.
The default port for SQL Express may not be 1433. To find the port it is listening on, right-click on the TCP IP protocol and scroll all the way down to the IP All heading. There should be a section called TCP Dynamic Ports. This should list the port SQL Express is listening on. You can then put this value into the port field when adding the connection profile via RazorSQL.
Make sure to restart SQL Express before trying to connect.

I had multiple NICs in my server. When I went to SQL Server Network Configuration -> TCP/IP and right clicked for properties there was a list of the NICs and at the bottom was the open port for my SQLEXPRESS. It was not 1433..... I do not know if there is a default but mine was in the 49,000 s.
How do you access a SQL Server 2005 Express Edition from a application in a network computer?
The access I need is both from application (Linq-to-SQL and ODBC) and from Management Studio
See this KB Article. How to configure SQL Server 2005 to allow remote connections.
Oh, and remember that the SQLServer name will probably be MyMachineName\SQLExpress
If you're running it on a 2k3 box, you need to install all updates for Sql Server and the 2003 server.
Check the event logs after you start the Sql Server. It logs everything well, telling you if its being blocked, and where it is listening for connections.
From a remote machine, you can use telnet to see if a sql server is listening for remote connections. You just need the IP and the port of the server (default is 1433). From the command line:
telnet 192.168.10.10 1433
If you get a blank screen, its listening. If you get thrown back to the command prompt, something is blocking you.
