what database are you using, if you are using MS sql, check if the user has access to the database, not only logon persmission. Looks like the user is not allowed to use the database. You can set users database access from sql login properties/Database access tab, check the databeses the user must have access to.
It appears that your Server may be using Windows Authentication
1. Right click on the server in Enterprise Manager
2. Click on "Properties" Menu Item
3. Click on "Security" Tab
4. Check the "SQL Server and Windows" under Authentication.
5. Click on the "OK" button.
6. Re-start MSSQL Server.

If it is a database access permissions problem, you'd have to ensure that the SQL Account used has access to the database concerned.
1. Expand the database you are seeking access to.
2. Click on the "User" item located on the left pane.
3. The dialog window "Database User Properties - New User" pops up.
4. Select the appropriate login, type the user name if not the same.
5. Check the appropriate roles.
6. Click on the "OK" button.
7. You do NOT need to re-start MSSQL Server

well then if it is a hosted site, you'd have to liase with them. You do not have full control on SQL Server.

If Mixed Security is set up then obviously, it is an database access permissions problem. To test this out, can you log into your SQL Server hosted by your ISP via Query Analyzer with the user name and password. This is a quick way to see if the account has access permissions to the db.

sql server of my site, dose'nt have a valid IP, so i can't check it with query analyzer, or other sql server tools,
i make a simple web application thet test the connection, and that application show the above error.

then you are working blindly. You cannot then say that you know the user account has the correct access permissions. I would say insufficient access permissions to the database, or incorrect authentication mode.

thanks b1xml,
it means that my user name and password is correct but, my login don't have my database permission .
"it means that my user name and password is correct but, my login don't have my database permission ."

Not necessarily.  I'm guessing they setup your login/password, but you don't have permissions to the  database they assigned as your "default database".

Call your host....
