How to configure SQL Server 2005 to allow remote connections

INTRODUCTION

When you try to connect to an instance of Microsoft SQL Server 2005 from a remote computer, you might receive an error message. This problem might occur when you use any program to connect to SQL Server.

For example, you receive the following error message when you use the SQLCMD utility to connect to SQL Server:
Sqlcmd: Error: Microsoft SQL Native Client: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.


This problem might occur when SQL Server 2005 is not configured to accept remote connections. By default, SQL Server 2005 Express Edition and SQL Server 2005 Developer Edition do not allow remote connections.

To configure SQL Server 2005 to allow remote connections, you must complete these steps:
  • 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.
This article describes how to complete each of these steps.

More information

To enable remote connections on the instance of SQL Server 2005 and to turn on the SQL Server Browser service, use the SQL Server 2005 Surface Area Configuration tool. The Surface Area Configuration tool is installed when you install SQL Server 2005.

Applies to
  • Microsoft SQL Server 2005 Developer Edition

Check dot net core framework version in my PC Or System

 Open My Computer → double click "C:" drive → double click "Windows" → double click "Microsoft.NET" → double click "Framework" → Inside this folder, there will be folder(s) like "v1.0.3705" and/or "v2.0.50727" and/or "v3.5" and/or "v4.0.30319". Your latest .NET version would be in the highest v number folder, so if v4.0.30319 is available that would hold your latest .NET framework. However, the v4.0.30319 does not mean that you have the .NET framework version 4.0. The v4.0.30319 is your Visual C# compiler version, therefore, in order to find the .NET framework version do the following. Go to a command prompt and follow this path: C:\Windows\Microsoft.NET\Framework\v4.0.30319 (or whatever the highest v number folder) C:\Windows\Microsoft.NET\Framework\v4.0.30319 > csc.exe Output: Microsoft (R) Visual C# Compiler version 4.0.30319.17929 for Microsoft (R) .NET Framework 4.5 Copyright (C) Microsoft Corporati...

ASP.NET Routing

ASP.NET routing enables you to use URLs that do not have to map to specific files in a Web site. Because the URL does not have to map to a file, you can use URLs that are descriptive of the user's action and therefore are more easily understood by users. The ASP.NET MVC framework and ASP.NET Dynamic Data extend routing to provide features that are used only in MVC applications and in Dynamic Data applications. For more information about MVC, see ASP.NET MVC 3 . For more information about Dynamic Data, see ASP.NET Dynamic Data Content Map . In an ASP.NET application that does not use routing, an incoming request for a URL typically maps to a physical file that handles the request, such as an .aspx file. For example, a request for http://server/application/Products.aspx?id=4 maps to a file that is named Products.aspx that contains code and markup for rendering a response to the browser. The Web page uses the query string value of id=4 to determine what type of c...
