First, put some debug code in that checks your connection string:
ConfigurationManager.ConnectionStrings["MRDDstringConnection"].ConnectionString;
If this is null (meaning the connection string does not exist for your current application), this is something you will need to fix. Also, make sure it has a username/password.
The third thing to check is how you are logging in. If this is a SQL Server, you may have Mixed Mode Authentication turned off for the database. You might be able to log in fine using Windows Authentication Mode, but remote applications will not be able to access the database until Mixed Mode Authentication is turned on.
You can read more about it here:
http://support.microsoft.com/kb/889615
Hope this helps.
|||<addname ="MRDDstringConnection"connectionString="server = khazad-dum; database = mrdd3;"providerName="System.data.SqlClient"/>
</connectionStrings>
that is the HTML i used for creating the connection string is something wrong in there?
|||
i found the problem in my html.....didn't work at all so thanks for all the help you got me started in the right direction
|||
Text should be:
<connectionStrings> <addname="MRDDstringConnection"connectionString="Data Source=khazad-dum;Initial Catalog=mrdd3;Persist Security Info=True;User ID=<username here>;Password=<password here>"providerName="System.Data.SqlClient" />
</connectionStrings>
Once you have this in your web.config file, you'll need to make sure you have Mixed Mode Authentication turned on. In SQL Server 2005, you can do this by right-clicking the server, go to Properties, select Security, and make sure "SQL Server and Windows Authentication Mode" is selected.
** PLEASE NOTE: You will have to put a username and password in the connection string above.
|||
i put in the username and password and it doesn't work it says i can't login...i know the username and password are correct...where is it checking for the user name and password cause my administrators are idiots...and they don't know what they are doing so i'm trying to figure out this part....
|||
Check to make sure Mixed Mode Authentication is turned on. What are you using for a back-end? SQL Server 2005?
|||
yes...the back end is SQL server 2005, and mixed-mode is turned on...and i created my username in the enterprise manage and set the permissions to the owner of the db....withouth the username and password i had it successfully going through with no errors, but it wasn't writting so now once the database knows its my user name i will be able to write to it...i'm lost at this point
|||
Are IIS, the .NET Framework and the SQL Server all running on the same machine? If so, make sure you are using a login that exists on the SQL Server (open SQL Server Management Studio and look under Security -> Logins).
The only reason you should get a Login failed for user '(null)' is:
1) there was no login ID supplied
2) the login ID supplied does not exist as a SQL Server login
3) mixed mode authentication is off
If mixed mode authentication is on, and you are supplying a login ID, we should start looking at the existing logins under SQL Server.
|||
ok, when i go look in the Enterprise manager the login name I'm currently under (MIRKWOOD\plan) that is the login name that shows up on the logins page, now i don't have to include MIRKWOOD in the html portion becuase of the fact that MIRKWOOD is the server name...but i tried just regular (plan) i tried (MIRKWOOD\plan), i tried it with the password i use, and without the password i use...none of them work...i have no clue...and the mixed mode authentication is on....also in the security tab it says "Audit Level" - "None" checked, "Ownership Chairing" - not checked, "Start and Run SQL server in the following account" - its a totally different user name and password i've seen....is that where the problem is?? maybe this will help you...sorry for being a hassel...i've just never delt with this before
|||
Put this in your web.config file (replace your old connection string):
<addname="MRDDstringConnection"connectionString="Data Source=<servername here>;Initial Catalog=<database name here>;Persist Security Info=True;User ID=<username here>;Password=<password here>"providerName="System.Data.SqlClient" />
You will have to change the Uesr ID and Password to a login you know exists.
I have to admit I am a bit confused. Earlier, it looked like you were trying to connect to a server named "khazad-dum" (neat Babylon 5 reference, by the way
) and a database named "mrdd3", but now it appears you are trying to connect to a server named "MIRKWOOD" and a database named "plan".
The User ID and Password would be the login as it exists in SQL Management Studio.
|||
I am trying to connect to a server name Khazad-Dum...that is where SQL server is located and my database...but my user name and password come from this other server name mirkwood....when i look in the security tab and then logins there is one under there called "MIRKWOOD\plan" now i'm almost 100% positive that is my login name but when i put it in my code it says that the name does not exist..really wierd...and my admin has no clue how he names stuff so i'm stuck here trying to figure this out...ughhh...if you have anymore suggestions that would be great...thanks for the help you have provided so far i understand everything you are saying and how it goes...i'm assuming it is the naming sequence...
