ProblemA new service, SQL Server Browser, was introduced with SQL Server 2005 and is also used with SQL Server 2008. In this tip I will cover what this is and how to use this service to improve your SQL Server environment.SolutionThe SQL Server Browser service introduced in SQL Server 2005, runs as a Windows service and it is an extension of SQL Server Resolution Protocol (SSRP) of SQL Server 2000. Like SSRP it plays an important role while working with more than one SQL Server instance installed on the same machine. The basic purpose of the SQL Server Browser service is to provide instance and port information to incoming connection requests.To configure a better and safe access mechanism for SQL Server, a DBA should have proper understanding of the SQL Server Browser service.Below I will discuss the access mechanism with reference to the TCP/IP protocol.How to access SQL Server Browser serviceSQL Server Browser service can be configured during installation or after installation it can be accessed in number of ways. Here are couple of common ways to access the SQL Server Browser service.Through Windows Services MMC. Access Windows services through the control panel or enter services.msc in the run box.Through a command promptThrough SQL Server Configuration Manager (SQL Server 2005/2008)Through Surface Area configuration (SAC, SQL Server 2005 only)It should be noted that SAC just provides access to start/stop or to change the startup type for the SQL Server Browser service. For management of all other parameters like ports, paths you have to use SQL Server Configuration Manager. Also SQL Server Browser service can be started by using command prompt.What if SQL Server Browser service is stopped?The SQL Server Browser service is installed with installation of SQL Server 2005/2008. It also serves earlier versions installed on the same machine if there any. The SQL Server Browser service has different impact in different situations, such as:If you have just one instance installed on machine and it is running on default port 1433, then status of SQL Server Browser service does not make any difference in your connection parameters.If there are more than

You can not have the browser service started for one instance and stopped for others on the same machine. If SQL Server Browser service is started, it would be serving all incoming connection requests.Same concept may be applied in case of clustering. You have to separately install and start the browser service on each node of the cluster.If you are using any type of firewall then do not forget to include UDP port 1434 in the exception list. UDP port 1434 is a port used by the SQL Server Browser service.If you are running SQL Server 2000 instance side by side along with SQL Server 2005/2008, then make sure to apply service pack 3 for the SQL Server 2000 instance. SP3 is required to work correctly with the SQL Server Browser service.It would be better if you have SQL Server Browser service with same settings on both development and production servers. It would prevent any problems due to differences of connection string information.Testing the configurationsI have a named instance with the following customized static port as shown in TCP/IP properties of instance in SQL Server Configuration Manager.If SQL Server Browser service is not running then start it through the command prompt or any of the other ways mentioned above.When the browser service is running, I can access the instance without a specifying the port. I can successfully login with the following connection parameters (IP + InstanceName).Now stop the SQL Server Browser service with net stop sqlbrowser command in the command prompt or one of the other ways that were mentioned above. Also exit SSMS and reopen it. Try to login again with the same parameters as before. This time you will get a message like the following.TheWindows XP Services - Computer Browser Service?
Special attention has been given to generate the smallest amount of rules when compiling filter lists into rulesets at extension build time.The current limit imposed by the various implementations is a guaranteed 30K. It is possible for an extension to use more rules, but anything above above the global limit will not be enforced. Currently, the global limit in Chromium is 330K static rules.The default ruleset in uBOL hovers around 17K when using Optimal or Complete mode (less in Basic mode).When also enabling all five Annoyances rulesets, three Miscellaneous rulesets, and one large regional ruleset, the total number of DNR rules is still under 30K.What are the upsides of an MV3-based content blocker?For Chromium-based browsers specifically, MV3-based content blockers which are entirely declarative will properly filter at browser launch, which is not the case for MV2-based content blockers. Not all MV3-based content blockers are entirely declarative, so these may still suffer filtering reliability issues at browser launch.Note though that this is not an issue for Firefox MV2-based uBO, see uBlock Origin works best on Firefox / Browser launch.Is uBO Lite a bad faith attempt at converting uBO to MV3?See goal with uBO Lite is a reliable and efficient MV3-compliant content blocker, leveraging the filter lists used by uBO. I am satisfied that I fulfilled that goal by ensuring uBO Lite was entirely declarative -- though at the cost of limitations beyond those intrinsic to MV3.Reliability: Being entirely declarative, uBO Lite's service worker is not required to initiate network-, cosmetic-, or scriptlet-based filtering in a timely manner.As a result, uBO Lite reliably filters at browser launch, or when navigating to new webpages while its service worker is suspended. This can't be achieved without uBO Lite's declarative approach. Example:ABP 4.1 (MV3-compliant): fails to filter properly at browser launch abp.mp4 uBO Lite 2024.5.29.835: filters properly at browser launch ubo.mp4 Efficiency: uBO Lite being entirely declarative means its service worker is lightweight and initialize optimally when activated.Non-declarative MV3-based content blockers will suffer unreliable filtering when their service worker has been suspended, since waking up a service worker requires a lot of initialization work and delays time-critical filtering abilities. Such content blocker may end up using trickery to force their service worker to always be up and running.For instance, ABP 4.1 uses such trick to keep its service worker alive and ready to act: the service worker is force-restarted each time it is terminated by the browser, so every 30 seconds when the browser is idle. Despite using this trick, there is still no guarantee reliable filtering will occur should timely filtering be required just as when the service worker is being woken up (all event handlers are non-blocking in MV3).Task manager: ABP 4.1 vs. uBO Lite 2024.5.29.835This is a capture of Chromium's task manager at browser launch.uBOL: Service Worker: chrome-extension://jifpbecc... entryABP: Service Worker: chrome-extension://cfhdojbk... entry. Notice the peaks in CPU and memory usage every 30 seconds. a-2024-06-02_10.50.36.mp4 The choice of being entirely declarative for the sake of reliability and efficiency meant sacrificing being able.

One instances running on the same machine, in that case either you have to start SQL Server Browser service or provide the port number along with IP (or server name) and instance name, to access any other instance than default.If SQL Server Browser service is stopped and IP along with port number is not provided then connection will be refused.If SQL Server instance is configured using dynamic ports then browser service is required to connect to correct port number.Also your named instances will not be published in the list of SQL Server instances on the network (which could be a good thing)Best practices for using SQL Server browser serviceThe way you use SQL Server Browser service affects the access to your SQL Server instances, hence the security of installed instances. At one end, the most security conscious approach may be to use customized static ports for your instances and access SQL Server with fully qualified connection parameters. It would include IP + InstanceName + Port. In this configuration your instance would not be exposed to the network also more parameters are required in the connection string.It would be a secure configuration compared to having the SQL Server Browser service running and serving the incoming connection requests with instance and port information. If you have no problem in using fully customized connection strings (IP + Name + Port), then you can stop the browser service permanently and access the instance through a fully qualified connection string.In another type of configuration, if the instance is configured to use dynamic ports each time, then SQL Server Browser service should be running, otherwise there would be no way to keep track of the dynamic ports that are assigned.If you have just a default instance installed (with default port) on your machine then SQL Server Browser service may be stopped to avoid overhead.As part of best practices, always run SQL Server Browser service with a minimum privileged account. According to BOL any Windows user having the following rights would be capable to run the SQL Server Browser service.Deny access to this computer from the networkDenyThe Computer Browser service depends on the Server service
Platform: The person identifier (such as a CRMID) that represents an authenticated user. The browser identifier (such as an ECID) that represents the web browser. Consider the following example: You log in with your username and password combination to an e-commerce website using your laptop. This event qualifies you as an authenticated user, thus Identity Service recognizes your CRMID. Your use of a browser to access the e-commerce website is also recognized by Identity Service as an event. This event is represented in Identity Service through an ECID. Behind the scenes, Identity Service processes the two events as: CRM_ID:ABC, ECID:123. CRMID: ABC is the namespace and value that represents you, as an authenticated user. ECID: 123 is the namespace and value that represents your web browser usage on your laptop. Next, if you log in with the same credentials to the same e-commerce website, but use the web browser on your phone instead of the web browser on your laptop, then a new ECID is registered in Identity Service. Behind the scenes, Identity Service processes this new event as {CRM_ID:ABC, ECID:456}, where CRM_ID: ABC represents your authenticated customer ID and ECID:456 represents the web browser on your mobile device. Considering the scenarios above, Identity Service establishes a link between {CRM_ID:ABC, ECID:123}, as well as {CRM_ID:ABC, ECID:456}. This results in an identity graph where you “own” three identities: one for person identifier (CRMID) and two for cookie identifiers (ECIDs).

A web browser is a special software program (application) used to retrieve files from remote web servers. A web browser can open Web-based HTML files, FTP connections, graphic images and other files. The browser application is smart enough to be able to tell the difference between these files and display them properly. Browsers are also created to be 'intelligent' enough to be able to 'learn' to handle even more types of files using 'plug-ins'.Web browsers are software. They run on your computer and do not connect you to the Internet. You use a web browser after you connect to your Internet Provider. A browser is not an online service like America Online, MSN or Compuserve. The online service provider provides telephone numbers and dial up connections. A web browser uses that connection to reach across the Internet and download files and information.Now, you should know that America Online purchased the organization that produced the Netscape browser. Because there was great confusion about what the Internet and Internet Service Providers are, the online service "Netscape" was created to take advantage of the confusion between web browsers and the Internet.Netscape and Microsoft Internet Explorer are applications not Internet Service Providers. There now exists a "Netscape" Internet Service Provider.Browser Applications The most well known browsers are listed below. InetDaemon.Com does not endorse any browser. The order of the listing of the browsers is in relation to the number of copies of the software installed on computers. Microsoft Internet Explorer tops the list only because it is automatically installed with the operating system and there are no options to remove MSIE from the installation in versions of Windows prior to Windows XP. By U.S. Government court order Microsoft has added a feature to Windows that will allow you to uninstall most of MSIE's functionality; however, Microsoft completely integrated the browser into the operating system and completely removing all functions of the browser would actually damage the operating system, or so was their argument to the court. Microsoft Internet Explorer This browser is automatically installed with Windows. No, you don't have a choice about it. You CAN set another browser as your default however. Available for Windows Mozilla Firefox Free web browser supporting plugins and renders web pages using the Gecko engine derived from Netscape originally. Available for Windows, Mac, Linux, Unix/Solaris Opera - Originally a strippded-down browser offering less functionality but greater page rendering speed. Available for Mac and Windows Apple Safari - Web browsing engine using the Apple WebKit rendering engine. Available for Mac and Windows Google Chrome - Web browser from Search Engine giant Google that uses the Apple WebKit rendering engine, but utilizes additional sandboxing and instance isolation features for better.

2025-04-05The epic journey of adapting our browser extensions to Manifest V3 is still on, and we've hit another milestone! Now the time has come for your faithful companion in ad-blocking: we are ready to announce AdGuard Browser Assistant v1.4, fully adapted to MV3.While using the extension, you may not even notice any difference in your user experience or in its overall functionality, but make no mistake: a lot has changed. Due to the limitations of the new API, adapting extensions to Manifest V3 is a laborious task, but the work needs to be done — slowly but surely, extensions are hopping on the MV3 train.So where are the changes then?In a nutshell, the background page is gone in the MV3 version of AdGuard Browser Assistant. The background page is responsible for a separate process, in which extensions could maintain their active status and work with the browser APIs. In Manifest V3, this page is replaced by a service worker, which is often interrupted by the browser. When the browser stops the service worker, the extension goes into a kind of sleep mode. For the extension to be functional, something must wake up the service worker: it can be loading a page or a message that has been sent to the service worker. In the AdGuard Browser Assistant v1.4, the service work is triggered by the AdGuard desktop applications themselves, to which the assistant is connected.Dealing with the service worker posed one of our main goals, but we encountered a few other necessary changes along the way. In our previous posts, we've delved into the process of transitioning to MV3 in detail, particularly with our AdGuard Browser Extension and AdGuard VPN Browser Extension. A lot of what we learned during those transitions turned out to be incredibly valuable as we developed
2025-04-15Reason is that the browser service is not running and the customized static port is also missing in the connection parameters. To login successfully we have to provide the customized port number in the following way. The server name field would need IP\InstanceName,PortNumber.Hopefully this has given you enough information to understand how the browser service runs and when and when you do not need to have this service running.Next StepsBefore making any changes to the SQL Server Browser service make sure that connection strings in existing code are changed to meet the changed configurations, otherwise you may have some connection issues.
