Desperate! Aspnet.mdf Screwed Up; User Login Impossible...

Aug 31, 2006

I hope anyone can help me with this. I am having problems connecting to the aspnet database.
It
all started when I noticed that I could not log in to my webapplication
anymore under debug mode, although I was able to log in when remotely
accessing the website. I got the error message that the machineaspnet
user did not have access to the database:  "Login failed for user
'GM-FEDORSASPNET' "

This was highly peculiar and rather annoying so I tried several things to straighten this out, but it only made things worse!
I
read that this had to with permissions of the database in question, al
though I could not understand why permissions suddenly had changed.
I
tried to change the rights by attaching it to Management Studio Express
and defining an aspnet login, but that failed because a login under
that name was not accepted.
I tried to make a copy of aspnet.mdf, delete the original and rename the copy to aspnet.mdf.
When that didn't work, I then deleted the aspnet.mdf, counting on it that it would be regenerated automatically, but alas.
I located the aspnet_regsql.exe tool to regenerate the database, but got the following error message:
System.Web.HttpException:
Unable to connect to SQL Server database. --->
System.Data.SqlClient.SqlException: 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. (provider: Named
Pipes Provider, error: 40 - Could not open a connection to SQL Server)
What can I do?

Login Failed For User 'MyPC/ASPNET'

Aug 11, 2006

Hi
I created my DB in SQL 2005 Express in VS IDE. I have my app in IIS. When I try to use the DB (e.g. try to login a user in the app) it gives me the following error:
Cannot open database "cvRepository" requested by the login. The login failed.Login failed for user 'MyPCASPNET'.
My guess was that I had to give permissions to ASPNET user so I did in SQL Server Management. Still not working! Checked my Connection string and I think it's fine...
connectionString="Data Source=.SQLEXPRESS;Database=cvRepository;Integrated Security=True;User Instance=True"
Still not working!
Can anyone explain me what's wrong and to solve this?!

How To Fix ASPNET Login Failed Problem With MSDE

Jul 9, 2002

I've searched all over the web trying to find a goddamn fix for this problem and no one has it right or they have the commands misspelled (!!!), so in spite of all those idiots, in spite of the makers of the Web Matrix guided tour for not pointing out this problem, and in spite of Microsoft who has not posted a solution themselves, here it goes:

* !! Change MYCOMPUTER below to the appropriate name of your computer !!
* Open a command prompt
* Type: C:
* Type: cd "C:Program FilesMicrosoft SQL Server80ToolsBinn" (or the exact location of the file "osql.exe" if different)
* Copy/paste the following commands

osql -E -S localhost -Q "sp_grantlogin 'MYCOMPUTERASPNET'"
osql -E -S localhost -d Orders -Q "sp_grantdbaccess 'MYCOMPUTERASPNET'"
osql -E -S localhost -d Orders -Q "sp_addrolemember 'db_owner', 'MYCOMPUTERASPNET'"

Jul 4, 2007

My system config is VISTA Ultimate, Visual Studio 2005 SP1, SQL SEVER 2005 SP2. Using 2005 SQL Server Management Studio I am unable to create a servername/aspnet login account.
I right click logins and get the new login form; key ASPNET Login Name; select Windows Authentication; click search; I get the Select User or Group form; under object type I select all three; location I select my server name; if I enter SERVERNAME/ASPNET and click Check Names I get an error; if I click Advanced and Find Now; ASPNET is not listed in Name(RDN) list.
I tried aspnet_sql.exe -E -A all; that did not work.
Where can I find information on creating an ASPNET Login after experiencing the above problems?

Login Failed For Localhost/aspnet - Please Help, Been Trying For Week To Solve

Nov 19, 2006

I am really at my wits end.  I have been trying for days to find an answer to this, and have tried so many things. 

I simply keep getting the error that localhost (Phantomlap in my case)/ASPNET cannot access the DB. This is a synopsis:.

Tools I am using:

V Studio 2005, IIS 5.1, XP Pro SP 2, SqlServer 2005 (using the EXPRESS server).

Configurations:


web.config:


<connectionStrings>
 <remove name="localsqlserver"/>
 <add name="localsqlserver" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|aspnetdb.mdf;Integrated Security=true;User Instance=True"
   providerName="System.Data.SqlClient" />
</connectionStrings>

Website is stored at:

C:Inetpubwwwroot
(within that I have an App_Data folder with following permission):
(I allowed, via security, the ASPNET account read/write access)

SQL Server status:
Phantomlap/aspnet user is added
Phantomlap/aspnet security as just about everything checkmarked

Please note--I am using SQLServer Express--I am not entirely sure I added the ASPNET account correctly--is there a tutorial on how to do this?

Please help,

Kind Regards

ASPNET User

Jun 10, 2004

I just moved my website to a shared host, and I face some trouble.
Since there is more than one DB on the SQL server they don't want to create a ASPNET user. Is there a way to make my SQLCommand use my user name instead of ASPNET ?

Otherwise, can anyone explain to me the result of the ASPNET user on other website who will use the same server as me security wise ?

How Do I Add ASPNET User To SQLExpress DB?

Sep 1, 2006

I am going though the ASP.NET QuickStart tutorials.  One of the lessons is to add a datagrid.  I am able to do that with VWD and am able to connect to the database in VWD.  However when I try to execute the application I get a "Login failure" message because the user pcName/ASPNET cannot login. How do I add the ASPNET user to the SQLExpress database?  There don't seem to be any administration tools that were installed with SQL Server Express 2005. Thanks in advance for the help!

User In SQL Server Is ASPNET?

Jun 15, 2004

I have developed an asp.net application and have deployed it to the web server. The application accesses an SQL Server to allow users to make changes to data. My connection string is the following:

"data source=" & ServerName & ";initial catalog=" & DatabaseName & ";integrated security=SSPI;" & "persist security info=False;packet size=4096"

On the SQL Server side, I have a trigger that logs when changes are made and by whom. The suser_sname returns <Servername>ASPNET as the user making the change. Why is this? Should it not be the user id of the user? If the SQL Server thinks that the current user is ASPNET then how can it make changes when this is not a user defined for the database.

The web site is set up to allow for Integrated Windows Authentication only. SQL Server is on the same machine as the web server.

ASPNET User In MSDE

Feb 18, 2005

Hello.

I am using MSDE in an ASP .NET application using forms authentication in order to the user can visit my website anonymously but have to authenticate in some pages.

Web server and MSDE server are in the same computer.

I would like to know how role I should set for the ASPNET sql server user. I am using Microsoft SQL Web Data Administrator and when I am creating the ASPNET user, then a page with some roles is shown.

Roles like public (default), db_owner, db_accessadmin, db_datareader, db_datawriter...

I had applied db_datareader and db_datawriter but now, when I use store procedures in my code, an error is made so I have applied db_owner role for the ASPNET user.

Is this correct or db_owner is a excessive privileged role for the ASPNET user?

Thank you and sorry for my English.

Aspnet User Can Not Access Sql Server

Sep 13, 2005

We have an ASP.net application that currently sits on a server that runs IIS and sql server. We are spliting IIS and SQL server into 2 seperate machines. I believe I have the connection string okay as I can see the entries in the security log on the sql server machine however it keeps saying aspnet user invalid user or invalid password.  What gives with this.  We put .net on the sql server however this just added the aspnet user to the machine. Do I need to create an aspnet user inside the sql server and give it control of the dbases as well?  I am running this using the personal web server not IIS on a server.  I have a project on my desktop and am using the "local" IIS or personal web server that comes with visual studio out of the box.  What kills me is that when I put the project on a real IIS server that has sql server on the same machine I have no issues.  However when I split the dbase and the IIS apart onto 2 servers I get this aspnet invalid user or invalid password.  HELP

ASPNET User With Network Resources Elsewhere On A Domain

Dec 6, 2004

I've been trying to workout how, without impersonation, I can allow an application running under the default ASPNET user to access a network resource (SQL Server/ADAM) not on the same physical machine.

It seems that because the ASPNET user is a local user not a domain user I can't setup windows authentication on the network resource. That seems to leave impersonation which MS et al say is unwise.

Have I mised something here?

Regards,

Steve.

Access Denied For User &<machine Name&>ASPNET

Jan 14, 2005

Hi!

I've just started to learn to use Visual Studio, and has come to database access.
I ran into this errormessage:

access denied for user <machine name>ASPNET

The book I'm using just only say that I have to grant the ASPNET user account permissions before the Web application will have access to a SQL database. ... Seems clear at first glance ... but I lack a "how to" ...!

---

I've tried to search the net for solutions ... several thousands of pages came up ... indicating that I'm far from the first who have this problem. ... So after I now have spend hours reading, without finding any useful ansver to the question. ...

So let me just tell the most popular answers. (So You don't repeat something I allready have read hundreds of times.):
This question has been asked before
Yes, true answer, but it doesn't help.

See the FAQ
If it was stated were in the FAQ to look it could have been useful.

Use something called "enterprise manager" (WIN XP pro, don't have this, though.)
I use WIN XP pro, so that answer dosn't help me either.

---

Hope some one can help.

SqlException (0x80131904): Cannot Open User Default Database. Login Failed. Login Failed For User 'xxxASPNET'

Jun 17, 2007

Hey Microsoft: this affects development that will eventually sell a lot of seats on SharePoint Server 2007. If you guys and gals can't straighten out this mess, you can't expect custom solutions with custom web parts. So pay attention for your own good. Yes, SPS 2007 is what this is all about. I've created simpe web parts and deployed them, same VS 2005, but I need local development and debugging for more complex stuff. I'm really disappointed that you have no solution for this problem.



I've seen other posts on this, but the result seems to be the same: if you fix it, it's by accident, not by design.



1. I created a blank ASP.NET web site

2. I added a web part manager

3. I added a web part zone



I get the error described above. I have no idea why SQL Server settings are so screwed up.



I've tried all the stuff in the other posts - security settings, command line installation, etc. None of those worked.



The default template(s) don't copy anything into App_Data, nor create an empty folder. I don't know why that is. I have other web sites working just fine, but they use remote SQL databases, or local ones I created, and didn't need profile management (no forms authentication, no web parts, no web zones).



I've also started out with a local database, using SQL Authentication, later moving it to a remote server, and never had any problems. The SQL Server developer edition and Express seem to work just fine. I can also debug stored procs when the .mdf is in App_Data. So the problem isn't one of connectivity.



What would cause the default screw-up? This would seem to point from all directions to a problem with Visual Studio (2005)? The installation is defalt - perhaps some extras included (copy local), but nothing unusual. AJAX for ASP.net is installed, but not used in the above "default web site" trial. Likewise Syncfusion's tools, which work fine on other developer workstations at this same location, all of which are from the same image (purchased at the same time & imaged). That web parts work on other boxes, running all the same management tools (anti-virus, remote sys admin/sms etc.) makes none of those suspect.



I think Microsoft needs to have a clean problem solution and publish it. SP1 certainly doesn't fix it. What's worse is the stupid, lame error message. "I can't open the default database". Well, what did you try? What do you think the default is? What settings are you using? Why is there no debugging information other than the usual worthless trace information showing it's all deep within the ProviderBase and SqlClient namespace code? How is that supposed to be helpful?



If anyone has anything solid, not guesses, I'd like to know.

Newbie Problems Adding ASPNET User To SQL Express Logins (Vista)

Apr 30, 2008



Hello,

I am trying to create an ASPNET Login for a SQL Server express Database (As Installed via Visual Studio) so my ASP Web Applications can invoke the Database. But SQLServer Managemnt Tool is not recognising any ASPNET user names I try.
I am trying to add via Microsoft SQL Server Management Studio Express, but get an error
" An Object (User or Built-in Security principal) with the following name cannot be found "mycomputerASPNET". "

Any obvious reason why ASPNET is not being recognised as a Login object object

Unfortunately I am on VISTA and IIS7 ( I have enabled, and checked that ASP Applications Run.)

- The process works OK on my other XP machine, ASP.NET via IIS 5.1, which seems more straightforward to set up.


Any help Appreciated, Since I am really stumped

Cheers

The Permissions Granted To User &&<MachineName&&>ASPNET' Are Insufficient For Performing This Operation.

Jul 25, 2007

Hi,



I wanted to deploy my Sql 2005 reports to my local machine and want it to get viewed by all the users through Asp.Net application.

User can directly view the reports by clicking on the direct link to report but when they try to view it using application having Report Viewer, running on iis it gives acess denied 401 error and can't view the reports

If I make my application to run on default port then it works fine

If I give rights to <particularMachineNameASPNET> then that user can view the report but if there are 100 users then will i Add 100 such entries???

I think I am making mistake in this case.

Any response will be appriciated.





-Thanks,
