Configure Windows Firewall for Database Engine Access

This topic describes how to configure a Windows firewall for Database Engine access in SQL Server 2016 by using SQL Server Configuration Manager. Firewall systems help prevent unauthorized access to computer resources. To access an instance of the SQL Server Database Engine through a firewall, you must configure the firewall on the computer running SQL Server to allow access.

For more information about the default Windows firewall settings, and a description of the TCP ports that affect the Database Engine, Analysis Services, Reporting Services, and Integration Services, see Configure the Windows Firewall to Allow SQL Server Access. There are many firewall systems available. For information specific to your system, see the firewall documentation.

The principal steps to allow access are:

  1. Configure the Database Engine to use a specific TCP/IP port. The default instance of the Database Engine uses port 1433, but that can be changed. The port used by the Database Engine is listed in the SQL Server error log. Instances of SQL Server Express, SQL Server Compact, and named instances of the Database Engine use dynamic ports. To configure these instances to use a specific port, see Configure a Server to Listen on a Specific TCP Port (SQL Server Configuration Manager).
  2. Configure the firewall to allow access to that port for authorized users or computers.Note
    The SQL Server Browser service lets users connect to instances of the Database Engine that are not listening on port 1433, without knowing the port number. To use SQL Server Browser, you must open UDP port 1434. To promote the most secure environment, leave the SQL Server Browser service stopped, and configure clients to connect using the port number.Note
    By default, Microsoft Windows enables the Windows Firewall, which closes port 1433 to prevent Internet computers from connecting to a default instance of SQL Server on your computer. Connections to the default instance using TCP/IP are not possible unless you reopen port 1433. The basic steps to configure the Windows firewall are provided in the following procedures. For more information, see the Windows documentation.

As an alternative to configuring SQL Server to listen on a fixed port and opening the port, you can list the SQL Server executable (Sqlservr.exe) as an exception to the blocked programs. Use this method when you want to continue to use dynamic ports. Only one instance of SQL Server can be accessed in this way.

Before You Begin

Security 

Opening ports in your firewall can leave your server exposed to malicious attacks. Make sure that you understand firewall systems before you open ports. For more information, see Security Considerations for a SQL Server Installation

Using SQL Server Configuration Manager

The following procedures configure the Windows Firewall by using the Windows Firewall with Advanced Security Microsoft Management Console (MMC) snap-in. The Windows Firewall with Advanced Security only configures the current profile. For more information about the Windows Firewall with Advanced Security, see Configure the Windows Firewall to Allow SQL Server Access

To open a port in the Windows firewall for TCP access

  1. On the Start menu, click Run, type WF.msc, and then click OK.
  2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
  3. In the Rule Type dialog box, select Port, and then click Next.
  4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number of the instance of the Database Engine, such as 1433 for the default instance. Click Next.
  5. In the Action dialog box, select Allow the connection, and then click Next.
  6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect to the Database Engine, and then click Next.
  7. In the Name dialog box, type a name and description for this rule, and then click Finish.

Implement remote blob storage SharePoint 2013

During my journey of installing, configuring and exploring SharePoint I came across an issue implementing Remote BLOB Storage (RBS).

In the first place I tried to configure RBS using the explanation on TechNet: Install and configure RBS in a SharePoint farm. Although it tells you in headlines what steps to take, it contains a few errors and is missing some bits and pieces.

Because of this i decided to write a blog post about the subject so that you won’t have to do all the research I did to get it working.

Okay lets start:

Prepare SQL Server

First of all you need to prepare your database to be able to use the FILESTREAM function that is used by RBS.

1.) Login to your SQL Database Server and open the SQL Server Configuration Manager
2.) Select the SQL Server Services and right-click on the SQL Server instance that hosts SharePoint
3.) In the Properties dialog click on the ‘ FILESTREAM ’ tab and select all check boxes.

remote blob storage sharepoint

remote blob storage sharepoint

4.) Click on Apply and OK to close the dialog box
5.) Close the SQL Server Configuration Manager

Okay the FILESTREAM is now available for this SQL instance. The next step is to activate the filestream by executing a stored procedure.
Sounds scary? It’s not just follow these steps.

6.) Open your SQL Server Management Studio and login to the SharePoint instance
7.) Now click the New Query button of hit CTR+N on your keyboard to start the Query Editor.
8.) Enter the following query and click Execute

EXEC sp_configure filestream_access_level, 2
RECONFIGURE

sql-query-editor

SQL query editor

9.) Restart the SQL Server service!

Provisioning the BLOB store

Okay we are almost halfway the configuration of the BLOB.

The next thing we have to do is specify a BLOB store. This is nothing more than a folder we’re the BLOB’s are stored.
This can be done by executing a set of queries in sequence. In the queries provided in this post you need to adjust a couple of settings to match your own environment.

In my example below I am creating a BLOB store for the record center where SP2013_Record_Center is the name of my content database.

use SP2013_Record_Center
if not exists
(select * from sys.symmetric_keys
where name = N’##MS_DatabaseMasterKey##’)
create master key encryption by password = N’Admin Key Password !2#4′

use SP2013_Record_Center
if not exists
(select groupname from sysfilegroups
where groupname=N’RBSFilestreamProvider’)
alter database SP2013_Record_Center
add filegroup RBSFilestreamProvider contains filestream

use SP2013_Record_Center
alter database sp2013_record_center
add file (name = RBSFilestreamFile, filename =
‘D:BLOBStore’)
to filegroup RBSFilestreamProvider

After executing this SQL Queries It’s time to check if the result is as expected.

10.) Open the path provided in your query and verify that there is a folder and file created.

the next thing we have to do is installing the RBS provider components.

Installing the RBS Provider

This is where it gets tricky when following the article on TechNet.
The article on TechNet provides the wrong link to the RBS Provider that needs to be installed on the SharePoint servers! They redirect you to a page to download and install a x86 RBS.msi instead of the x64 bit version.
This Provider needs to be installed on all Front-End and SQL servers.

11.) The correct link to the download is RBS.msi
12.) Open the cmd window as an Administrator and browse to the download file is on the machine waiting for you to be installed.
13.) Copy and paste the command provided below in to the cmd window.

msiexec /qn /lvx* rbs_install_log.txt /i RBS.msi TRUSTSERVERCERTIFICATE=true
FILEGROUP=PRIMARY DBNAME=”SP2013_Records_Center” DBINSTANCE=”MSSQLSERVER”
FILESTREAMFILEGROUP=RBSFilestreamProvider FILESTREAMSTORENAME=FilestreamProvider_1

Again change the name of the content database (SP2013_Records_Center) and the Instance name (MSSQLSERVER) matching your own server.

14.) Fine, now that’s done check the log file that sits at the same location as the initial .msi file. Somewhere at the bottom there should be shown a Completed Succesfully message.

We’re almost done now 🙂 the only thing needed, besides testing, is enabling RBS for the content databases that you want to use.

Enable Remote BLOB Storage for the content databases.

15.) The easiest way to do this is using the SharePoint management Shell. Make sure you run this as Administrator.

First of all we need to get the content database for the web application. After we placed the content database in a variable we can use it to change the settings of that content database.

Sound all very difficult but it is not. To make it easy i wrote a PowerShell function that does the job. The only thing you need to do is run the script and tell the script what the URL of the web application is.

$cdb = Get-SPContentDatabase –WebApplication
$rbss = $cdb.RemoteBlobStorageSettings
$rbss.Installed()
$rbss.Enable()
$rbss.SetActiveProviderName($rbss.GetProviderNames()[0])
$rbss.Installed()

Configure the minimum file size (Threshold)

The last thing that needs to be done is configuring the minimum file size for the files that needs to be stored outside the content databases. By default this is set to 60 kb but I would recommend to change this to 1 MB.

16.) Open up the good old PowerShell again and execute the following code.

$cdb = Get-SPContentDatabase –WebApplication
$cdb.RemoteBlobStorageSettings.MinimumBlobStorageSize=1048576
$cdb.Update()
Migrate data from or to the RBS

If you activate RBS in an existing SharePoint environment you might want to move the current data out of the database to the BLOB location. Again this can be achieved through PowerShell.

17.) You might have guessed it already, Open PowerShell to execute the following code.

$cdb = Get-SPContentDatabase –WebApplication
rbss = $cdb.RemoteBlobStorageSettings
$rbss.Migrate()

Depending on the amount of data in your databases this can take quiet a while.
