i tried everything possible to fix this but nothing worked for me ,pls help me to create a table on my database .
AS your question title says, the error is a clear problem with your user autentication. This problem may be due to a very large list of causes, but I will give you what in my humble opinion is a quick troubleshooting that may lead you to solve this problem:
First of all, check the permissions of your user on the specified database. Using SQL Server Management Studio, right click your user, properties, then user mapping. Right there you have to check for the correct database mapping and the desired role.
Check server authentication mode, to see if it is on mixed mode. In many cases, I´ve seen many installations where the authentication is set to windows only, and users keep getting this message having the correct permissions on user and correct mappings.

I have a strange issue when trying login to my WPF application I published. I am using Microsoft SQL Server 2016, I am also a Server admin. I have a Database called Project Tracking in the server. When trying to log in I am able to login just fine. When another user tries to login they get this error: The underlying provider could not be opened.
Now, if I add them as system admins to the SQL server they are able to login just fine no errors. Although this is not what I want to do for obvious security reasons. How do I go about actually adding them for read/write access to the database?
The connection string in the application is: "metadata=res:///Model.ProjectTracking.csdl|res:///Model.ProjectTracking.ssdl|res://*/Model.ProjectTracking.msl;provider=System.Data.SqlClient;provider connection string="data source=EPLANDB\PROD4W;initial catalog=ProjectTrackingDB;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient"
This is my first go around using SSMS and SQL Servers, so not sure what exactly the problem is or how to word it correctly, I hope I gave enough information if someone could point me the right direction.
Here is a picture of my setup on SSMS.
I figured it out. I found this article over the subject and it worked for me.
I had to go into Security for the Server right click Logins and hit New -> Login.
Your are then brought to this screen. Click Search...
Not sure if this part matters. But I clicked Object Types and checked the Groups.
Add the username you want to include. Make sure to include the domain name.
Click User Mapping.
Check Your Database.
Make sure to check data reader and data writer and any other roles you would like to include.
Here is where I found the solution.
Answer to Problem
I have searched high and low for a solution to this problem to no avail.
Basically, the situation is as follows:
We are currently migrating our existing TFS server to another machine, which has been going well up until now.
Unfortunately i'm unable to complete the configuration of Report server and the likes as I get the following error:
"Failed to add SWSERVER\susan account to the TFSEXECROLE role on the Tfs_Warehouse relational database"
SWSERVER is the name of the previous machine that hosted the TFS server.
The thing is that SWSERVER\susan is an absolete account, and was actually removed as a user account on the previous machine, which I think is a major part of the problem.
From what I can gather is that TFS can still see it in the restored databases and thinks it's a viable account but seeing as the account technically doesn't exist it can't actually do anything with it.
Another part of the question is that if I go to the original (SWSERVER) and remove the SWSERVER\susan user, will that have an effect on how TFS or SQL operate especially if that account (or any other similar account) are linked to anything in either program?
I'd much appreciate any help anyone can provide.
I've hope i've explained my situation well enough but if anybody needs any more information, please don't hesitate to let me know.
You can't remove users, they will fall out of scope anyway, however that is not your problem. Your TFS instance has been moved from one server to another without following the documented procedure.
You need to follow the instruction to Move Team Foundation Server from one environment to another. Although they will be based on the more common move of Domain to Domain you can think of a non-domain joined server as having a domain of the same name as the local computer.
Now this documentation also follow as using the same hardware so you will need to mix and match between Move Team Foundation Server from one environment to another and Move Team Foundation Server from one hardware configuration to another.
While not really that hard you do need to follow all of the steps...
Just want to thank you for your reply and help. As it turns out I was flogging a dead horse with the TFS Reporting setups when I found out that the reports aren't even used currently on the existing setup.
I did however manage to figure out that if I added every user that previously existed as Windows users on the new machine and then used the TFSconfig Identities /change command to change the domain (machine name, in this case) name to that of the new server then I stopped getting the error messages and after 3-4 reinstall attempts all seems to be working the way it should.

Recently I inherited a database from another programmer (created / stored with SQL Management Studio 2008), and I am having massive difficulties accessing, modifying, or even viewing the previously created databases.
Specifically, when I try to load one of the databases in SQL Management Studio I get the following error message:
"The database [database name] is not
accessible. (Object Explorer)"
I am connecting to the SQL server with windows authentication.
Anyway, is this a permissions issue left over from the last dev? (he's unavailable, unfortunately) And is there an easy work-around short of completely reinstalling SQL Management Studio?
Edit: Update:
Upon trying to access User Mapping, as suggested below, I got the following error message:
"One or more databases are inaccessible and will not be displayed in list."
Unfortunately, none of the databases I am trying to access appeared in the list, so I assume they are still inaccessible.
It could very well be a permissions problem. If you open Object Explorer in SQL Server Management Studio and expand the Security node (the one under the server instance, not the Security tab under the individual databases) and then expand the Logins node you'll see the list of logins that have been created on the server. Have a look at the properties of each of those and check out the User Mapping information. You'll be able to see which logins are mapped to which databases. It's possible the previous programmer only granted access to the database to certain logins. If you find a login that's mapped to the database you want, try changing the password of the login and then connecting to the database with that login and password. NOTE: be careful when changing the password as it may affect production applications that are using that login and password!
This message:
"One or more databases are inaccessible and will not be displayed in list."
Means that the user you are using right now cannot access to that db. If you can enter with a user that does have access and from that user change your actual user's rights through User Mapping, then you will see it.
You need a dba (or someone with dba equivalent access) to give you rights to the database.
I am developing a web app that connects to a SQL 2000 database. Everything works perfectly on my database (which is actually SQL 2008) but when I try to migrate it onto another server (that's actually running SQL 2000) I get some strange errors.
I'm getting Login Failed for the username that the web app uses, so I did my normal troubleshooting steps...
I reset the password to what it should be, made sure the user was mapped to the database it's trying to connect to. I connected to the database through Enterprise manager using the user name and password and was able to run queries. I reset the SQL server.
I'm fresh out of ideas other than there might be a place in my app that the password is for some reason getting changed. Is there anyway to see what password the SQL server is seeing? I just want to narrow down my search a little.
Either that or does anyone have any other suggestions on how I might be able to fix this?
EDIT: Also, the web app CAN talk to the database, it hits the database to get login credentials and it can login with no problems. The error is coming up later in the app when I try to get more information from the database, like parameters for a report or an export location.
Thanks in advance!
First, the problem is not that the login failed for a user. From your description, the login succeeded. However, you stated that you later got an exception when trying to access certain objects. This sounds like an authorization/permissions issue with the database user to which the login is associated and the objects it's trying to access. Have you tried connecting to the database using Enterprise Manager and the same credentials used by the site and executing the identical query as the web application?
Possibly your SQL server isn't set to allow remote connections?
EDIT: or your firewall doesnt have the right ports opened?
EDIT2:
If your web script is on the same server as the SQL server, the only thing that i can think of is that you have specified an incorrect password, of if you referenced the old server by name (even though it was localhost) and you have not updated it. If the web script is on a different server, check your firewall ports and ensure the sql server is set to allow remote connectioins.
EDIT3:
Appologies, i didn't see your update before i posted the last edit (EDIT2). Thomas is right, give that a go.
Not sure how you're doing your migration but you may want to make sure your sql user is not getting orphaned:
From - http://www.fileformat.info/tip/microsoft/sql_orphan_user.htm
First, make sure that this is the problem. This will lists the orphaned users:
EXEC sp_change_users_login 'Report'
If you already have a login id and password for this user, fix it by doing:
EXEC sp_change_users_login 'Auto_Fix', 'user'
If you want to create a new login id and password for this user, fix it by doing:
EXEC sp_change_users_login 'Auto_Fix', 'user', 'login', 'password'
I found the problem!
It was actually some lingering queries I had in the app. I started populating some down downs differently and the queries were never removed, as soon as I took those out the errors stopped popping up.
Still it's strange that this would not effect the app on my machine but on this other machine would cause all kinds of havok.
Thank you all for your help and suggestions, it really helped narrow down the problem. Thomas gets the accepted answer though because his suggestion pointed me in the right direction.
Lately there has been a problem running some of our reports in access. Last week(the beginning of the week) we tried to run a reports lets call it A and it kept giving us the log in prompt. Even when the correct user-name and password were entered the log in box would just keep reappearing until cancel was pressed.
I clicked the debug and checked the query. I then logged into the database it is pulling the data from with the same user-name and password and received no trouble. Around Wednesday A was working again, even though nothing was changed. This week A is working but another report B is doing the same thing..
Anyone have any idea what this could be? I'm thinking maybe someone else has the report open? Any help is appreciated.
EDIT: I have narrowed down the error to one linked table that is causing the login prompt. It seems it has the DSN setup but no database specified. So i just need to relink the table..Is there anyway to do this at the GUI level? Also should I leave this question up for future users or just delete it?
Was the login prompt from Access or from Windows? If from Windows, then I'd say that there was some sort of file permission or network access issue at hand. If from Access, then I would say that something in the SYSTEM.MDW that you are using is corrupt or has been reconfigured.
If the login prompt is from ODBC it probably means that the credentials that are being used to access the backend database (per your comments you mentioned it was SQL Server) are either invalid or disabled. (Or it could be as simple as the backend database is/was temporarily unavailable).
If you are using linked tables in Access to a SQL Server it means that an ODBC connection was created and you might try verifying that the ODBC connection is working ( Control Panel, Administrative Tools, Data Sources(ODBC) ). In that dialog there is a place to test the connection.
