Think of this as the target IP address for the packets coming in through this rule, whereas the Remote IP addresses are the source IPs. This is referring to the IP addresses of the server. Optional: for additional security, go back in to each of your firewall rules and set the Scope to restrict access to the Local subnet (assuming all valid connections come from inside your local network):Īnd yes, the top half of that dialog, Local IP address, is intentionally set to Any IP address. Create an inbound port exception for UDP 1434:Īt this point, you should be able to connect remotely to your SQL server.ģ. The limitation comes from DB level or OS level. If I shall use Server version of OS then what can be the max concurrent user connections. of connections for SQL Server 2012 Express: the number of connections is limited or unlimited. It is the limitation of instance based or per database based No. Another TechNet article says that the Browser service uses UDP connections to port 1434. The limitation of SQL Server 2012 Express is 10 GB. What wasn’t clear is that the SQL Server Browser service also needs a firewall exception. So for SQL 2012 Express, create an inbound program exception allowing access to C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\Binn\sqlservr.exeĢ. This TechNet article says that when using dynamic ports, the inbound firewall on the server needs to allow access to the slqservr.exe program, not a port. This is the area where things seemed a little ambiguous.ġ. In SQL Server Express user connection limit is 32,767. You can do that from the SQL Server Services node by right-clicking on SQL Server (SQLEXPRESS) and selecting Restart. After you enable TCP/IP connections, you’ll be advised that you need to restart the SQL Server for the new setting to take effect. You can also look at the Properties, but they should already be set to allow dynamic connections.Ĥ. On the right side, right-click on TCP/IP and click Enable. Still in SQL Server Configuration Manager, on the left side, click on the SQL Server Network Configuration node, then highlight the Protocols for SQLEXPRESS node. SQL 2012 is not on there, and according to some other documentation Ive found, SQL 2012 is only compatible with Server 2008 (plus R2) and Server 2012 (Plus R2). Go ahead and start it manually now (right-click on SQL Server Browser and select Start).ģ. That will start it automatically whenever the server boots. On the Service tab, set Start Mode to Automatic. On the right side, highlight the SQL Server Browser service, right-click, and select Properties. In SQL Server Configuration Manager, on the left side, highlight the SQL Server Services node. Click on Connections, and in the right pane, check Allow remote connections to this server.Ģ. In SQL Management Studio, right-click on the server name and select Properties. This part seems pretty well documented but I’ll repeat it here for completeness.ġ.
You can reconfigure it to use a fixed port, but I wanted to see if I could get it to use dynamic ports. the port number can change whenever SQL starts. That’s important not only because you need that name to make network connections, but because named instances by default use dynamic TCP ports for their connections, i.e. if your server is named SVR2012E, your default SQL Express instance will be named SVR2012E\SQLEXPRESS. That’s the “SQLEXPRESS” in the SQL server name, e.g. SQL Server Express is by default installed as a named instance. There is so much information about network and firewall access, I wanted to write down what worked for me. I’m using it to host GoldMine CRM databases.

Then tried to attach the database again and it worked.I’ve recently installed SQL Server 2012 Express SP1 under Windows Server 2012 Essentials. It was related to a path issue regarding the. mdf file I got from this sample project from DayPilot: Scheduler for ASP.NET MVC 4 Razor (C#, VB.NET, SQL Server).
