Cannot connect to Sql Server Local Instance

Posted By:      Posted Date: September 12, 2010    Points: 0   Category :ASP.Net
 
Hello allI just installed sql server 2005 to my pc and when i try to log in to the server instance i get an error log in failed for user xxx (error 18456). I browse to the server instance and i keep getting the same error even though i chose windows authentication option during the installation. I restarted the service for the sql server instance (which is running).The only problem i can think about is a problem with permissions but again there should not be any problem there because i logged in as administrator. Any suggestions please!!!

Can't connect to SQL 2005 Enterprise using Management Studio with Server Name (only (local) works

  
This is a test system, everything running locally & no domains. Win 2003 Ent. Server & SQL Server 2005 Enterprise. I can't log into SQL Server Management Studio using the server name & using either Windows Authentication or SQL login. If I change the name of the server in the drop-down list to "(local)", I connect just fine (both Windows & SQL security modes). Shared Memory, Named Pipes & TCP/IP enabled in both server & client. Remote connections allowed. I have IP adresses (both 127.0.0.1 & external IP) in my hosts file pointing to the server name. Does SQL require a DNS server? This wouldn't be a problem except for the fact that I can't install SQL 2005 SP3 due to authentication failure since there's no way to enter (local) as the server name. SQL tools (management studio, SP install) seem to see the SQL server running but won't authenticate the user through any means other than setting server name to (local). This is driving me crazy!!!

Failed to generate a user instance of SQL Server due to failure in retrieving the user's local appl

  
Hello everybody.I am working on Login control and I am new in ASP.NET. So far what I did is :1. In Website->ASP.NET Configuration I change the form authentication to internet.2. I created a user profile3. This gave me a ASPNETDB.mdf database.4. I added this code :<connectionStrings> <remove name="LocalSqlServer" /> <add name="LocalSqlServer" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/> </connectionStrings> in web.config file.4. I added login control to my login page :<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Login.aspx.cs" Inherits="Login" Title="Untitled Page" %><asp:Content ID="MainContent" ContentPlaceHolderID="MainContentPlaceHolder" Runat="Server"> <h1>Please Login</h1> <asp:Login ID="LoginAuth" runat="server" > </asp:Login></asp:Content> 5. And the login.aspx.cs file has :using System;using System.Collections;using System.Configuration;using System.Data;using System.Linq;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.HtmlControls;using System.W

Can not connect to user instance of SQL Server 2008 Express with Advance Services in Visual Studio 2

  
I used SQL Server 2008 Express with Advanced Services (not SQL Server 2008 Express) in Visual Studio 2010 because it is the fast and easy way to developed and managed data-driven applications with powerful built-in reporting and full-text search functionality. I received Sql Server 2008 Service Pack 1 with Windows Update. It's ok if I connect to instance of SQL Server 2008 Express with Advance Services (with SP1) through SQL Server Management, but if I try to attach a database in Server Explorer (Visual Studio 2010), I get the following error: "Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed." I'm stuck at this point. Is there a fix or a workaround? I've already tried deleting the 'C:\Users\Administrtor\AppData\Local\Microsoft\Microsoft SQL Server Data\SQLEXPRESS' directory as mentioned in other posts, with no luck. The error.log at 'C:\Users\Administrator\AppData\Local\Microsoft\Microsoft SQL Server Data\SQLEXPRESS\error.log' has the following relevant entries: 2010-09-01 14:44:10.47 Server      Error: 17156, Severity: 16, State: 1. 2010-09-01 14:44:10.47 Server      initeventlog: Could not initiate the EventLog Service for the key '3677F6D3-17C7-4F', last error code is 2. 2010-09-01 14:44:10.47 Server &

local pipes vs. network pipes (to connect to SQL Server)

  
Choosing a Network Protocol (SQL Server 2008 R2) tells: "It is also important to clarify if you are talking about local pipes or network pipes. If the server application is running locally on the computer that is running an instance of SQL Server, the local Named Pipes protocol is an option. Local named pipes runs in kernel mode and is very fast" Well, it is not me who is talking in cited article, I believe so. Should it be understood that "If the server application is running locally on the computer that is running an instance of SQL Server" and configuring/choosing Named Pipes mean running "local Named Pipes"?

connectivity issue with local instance of sql server

  

hi everbody,

well for the last couple of days i have almost taken my head out to get this issue resolved.

but still i am no where. i have already referred to so many tips available online but still can't fix the prob.

i am trying to connect a C# ( .net 2005) program to connect to the  integrated sql server 2005 instance on my local computer.

i have got windows 7 home basic on my pc with .net frame work 2.0 sp2 and have also upgraded to sql server 2005 sp3 as per some online study.

i have also tried all these steps but still getting the error 40.

1. Check Whether the SQL Server is running or not.
Because the trial to connect to the stopped server may also cause this problem.

2. Check the name of the SQl Server.
For example, if we try to connect to SQL server using .NET application, for some SQL Server, the name of the server "localhost" works, but for some server, we may need to mention "(local)".

3. Check Whether the SQL Browser Service is running

4. Check Whether the TCP/IP is enabled for SQL Server Configuration

* Expand SQL Server Configuration Manager
* Enable TCP/IP

5. Firewall Settings

You may need to add the port of Sql server to the Firewall if it is other than the default port(1433).

SQL Server Express2008 R2 brings app down, instance problem

  

I have tried dozens of changes and modifications to many settings as I will outilne here and all to no avail.

The short answer here though is that I uninstalled SQL Sever Express 2008 R2 and went back to the "NON" 2008 R2 and got things working. But like the fool I am wanted to run on the more current rev and updated again, all problems returned....

SPECS

Server:

Win Server 2003 R2 SP2

SQL SERVER EXPRESS 2009 R2

VWD2008 Express (removed)

IIS 6

 

Workstation:

XP Sp3

VWD2008 Express

SQL Server Express 2008

 

I was orginally getting this message after updating to SQL Sever Express 2008 R2, I removed VWD 2008 Express from the web server, no good, then uninstalled SQL Server 2008 Express R2 and reinstalled SQL Server 2008 Express. worked but had issues, couldn't install MGTM Studio. Then I removed SQL 2008, cleaned folders and reg. Reloaded SQL Server 2008 Express, still flaky, couldn't get the Management Studio to install. So I removed it again and used the Web Platform Installer, which worked but loaded 2008 R2 again. Which brought back the message.

Pick up old local users on new server with new local users with same name

  

Hi, All!

I has old server with name "test", worked with SQL server 2008 and Sharepoint 2007 SP2. There was five users like "user1", "user2", etc. They have content on main page "http://test" and some data at mysite host "http://test:81". Well I create new server with the same name "test", create all users "user1", "user2", etc, then i add them to shared services profiles with the same names like in old server. Then from old server backup content base from MS SQL server for applications on 80 and 81 port, and restore them on new server. Then I make commands "stsadm -o addcontentdb -url http://test -databasename wss_content_80" and "stsadm -o addcontentdb -url http://test:81 -databasename wss_content_81". Then I delete databases which created when i create new web applications from sharepoint central administration. and did iisreset. Well all data and settings picked up, BUT all user ID were old. So question is: how i can compare old users to new? I want to compare old and new users everywhere in DBs wss_content_80 and wss_content_81. Like replace old ID with new ID


sqlcmd, cannot connect to server

  
I have SQL Server installed on a machine called SQLDEV. I log on to that machine and I run the command sqlcmd -s SQLDEV -Q "select * from <db>.<schema>.<some_table> -E This command works and returns a result set.   Next, I go to a different machine. On that machine I can use SQL Mgmt Studio to log on to SQLDEV using window authentication. However, if I run the same command as above, I get some kind of a connection error. The error says, ".... 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 .....   Any suggestions/ideas why I am getting this error?
