I need help connecting from a blank access 2010 database to my remote SQL Server 2005 database. This is because I'm going to write all my client apps in Access, and store everything on the server with SQL Server. I'm using the wizard, and trying to make a new DSN. What do I put for:
Which SQL Server do you want to connect to?
Server:
The server is windows server 2008, and it is remote. I've been connecting to it with a .RDP file, but I'm not sure how to set up the link.
Please ask me to clarify anything that doesn't make sense.
Thanks.
Enter the IP address or the Windows Host Name for the server that has SQL Server on it.
You'll need to make sure that your server has port 1433 open in it's internal software firewall. If you're going through any kind of router that router will also need to have port forwarding and possibly the firewall opened up for port 1433.
Also, you'll need to make sure that your SQL Server instance is setup to listen on TCP/IP with port 1433 (unless you choose a different port).
You might be best off trying to connect to it from SQL Server Management Studio first. Once you have that working you should have an easier time setting up your DSN.

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 have a client for which I am setting up a new SQL Server Express and (on a different computer) connecting their Access front end to that SQL Server. I created an account on SQL Server, changed authentication to SQL Server. I am able to log on to that account with no issues locally (through SQL Server Management Studio) on the server itself, but when I go back to the client machine and try to create either an ODBC connection or connect directly in Linked Table manager, I get the error below. Looking at the error log in SQL Server I can see no failed logins. In Access and/or ODBC I use Servername\SQLEXPRESS, choose SQL authentication and type in the username/password that I created. But it's still being stubborn.
I'm kind of at my wits end with this one. I checked to make sure that login is enabled, that the created database is mapped to this user, but I'm out of answers. Anyone have any ideas? I'm sure it's something really stupid that I'm overlooking, I've used SQL Server for a long time but I'm not an experienced DB Administrator I'm sure it's something really simple I'm overlooking, but I've done this hundreds of times before. And Windows Authentication won't work because it's on a different computer.
To connect to a named instance on SQL Server Express with Servername\SQLEXPRESS, you need:
SQL Server Browser service running,
and its UDP port 1434 open in the firewall.
https://learn.microsoft.com/en-us/sql/sql-server/install/configure-the-windows-firewall-to-allow-sql-server-access
SQL Server Browser service
UDP port 1434
The SQL Server Browser service listens for incoming connections to a named instance and provides the client the TCP port number that corresponds to that named instance.
The fixed TCP port for your instance open in the firewall.
You set this in SQL Server Configuration Manager
https://learn.microsoft.com/en-us/sql/database-engine/configure-windows/configure-a-server-to-listen-on-a-specific-tcp-port
This looks more like a network setting rather than server issue.
Check if all necessary permissions, configuration and settings on your machine running the server are OK to accept external connections.
Usually its the server that is rejecting the connection for security reasons.
Alright, I know this sounds pretty basic, but it is eluding me. I have a local server with SQL server 2017 installed (Express Edition, because - Free). I can access the database when remoted into the server without issue. The problem is when I try to access the server using the public IP rather than the local hostname. My router has this server in the DMZ currently and port forwarding is setup for port 1433. The server firewall is currently even turned off and I still cannot see it.
The SQL server does have TCP/IP enabled, it is listening on port 1433.
If you need any further information, let me know. I've been troubleshooting this for two hours and just lost at this point. I am no where near new to technology and servers, but not too familiar with SQL Server.
Make sure you have enabled remote connections.

I dont have much experience with MsSql. I have no problem to connect to database by SQL management studio with SQL Server Authentication Mode on ip 127.0.0.1.
But my program fails to connect. I created file connect.UDL for test connection and got this error
[DBNETLIB][ConnetionOpen (Invalid Instance()).] Invalid connection
Some information may usefull
SQL server is on configured as Mixed Authentication Mode
DIsabled my firewall
Enabled all protocols (Shared Memory, Pipe names, TCP/IP, VIA)
Using 127.0.0.1 and 1433 port for TCP/IP protocol
Allowing remote connection on server
Can provide more information if you need. Thanks
EDIT : I deleted everything and installed SQL SERVER 2008 R2. Everything working now. Thanks all for your effort.
Ensure you have installed SQL Server as a "Default instance" in order to be able to connect with just the IP address or hostname. If it's a "Named instance" installation, you will need to specify the hostname and instance name to connect. (i.e. MY_HOST\MY_INSTANCE)
Check out the SQL Server Configuration Manager, and under SQL Server 2008 Services section, does the installation have the "Names instance" in brackets? - That's your named instance.
How do I connect to SQL Server 2005/2008 using Management Studio or other desktop application over the internet?
Check out WCF Data Services:
http://msdn.microsoft.com/en-us/data/bb931106.aspx
That way, you don't have to totally expose your database server out to the internet, but you get fine grained control over what gets exposed and who (which type of user) can see or modify what.

I finally solved this by:
Changing default SQL Port to 8080 from 1433 (our ISP was blocking)
Turning off Windows Firewall on the server. I know this is not a long term solution, but at least I was able to pinpoint the problem. I had set two inbound firewall rules to allow port 8080 and SSMS program, on the server. I created an outbound firewall rule on the client for SSMS (but don't think this mad a difference).
I had to change all apps to use the new port instead of the default port. I had to configure our router to handle the new port 8080 and forward to the database server.
I will modify the Windows Firewall settings to see what was blocking SSMS.
DB Server: Windows 7 Pro 64bit 24 GB RAM
If you put 'your' SQL server (any brand, I'm not bashing) on the internet ... it won't be yours for long, unless you add some rather effective security measures ...
I suggest you look into VPN.
To be able to access your database over the internet, you will need to make sure that the server that hosts the database is accessible over the internet and the port that the database instance uses is open on that machine. You will also need to allow remote connections using the SQL Server Configuration Tool.
For Management Studio access I would recommend rather than opening the server to the outside to use a VPN solution that allows you to create a secure connection to the server and from there you can use the server name or IP to connect as if your machine is part of that network.
For the desktop application I would recommend looking into having the data be consumed through a web service or WCF rather than needing to have a direct connection to the database over the internet.
Hope this helps.
Firstly, if we put security consideration on the side, you have to configure SQL server (sql surface area configuration) to accept traffic, then you have to open proper ports on you server and allow inbound traffic thru to your router to the SQL server.
When you open sql server management studio in connect to server window and at the server name type the IP of your server and enter your username and password.
correct format : IP\InstanceName
you should have a user on target database.
