Cannot open database “DataLayer.Context.MedicallexiconContext” requested by the login. The login failed.
Login failed for user ‘CL-xcsd-\medicallexicon_web’.
this is my context

public class MedicallexiconContext : MyDbContextBase, IUnitOfWork
    {
        public DbSet<Word> Word { get; set; }
        public DbSet<Category> Category { get; set; }
        public DbSet<Language> Language { get; set; }
        public DbSet<Picture> Picture { get; set; }
        public DbSet<RelationshipBetweenWords> RelationshipBetweenWords { get; set; }

        #region IUnitOfWork Members

        #region IUnitOfWork Members
        public new IDbSet<TEntity> Set<TEntity>() where TEntity : class
        {
            return base.Set<TEntity>();
        }

        #endregion

        #endregion

        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Configurations.Add(new CategoryConfig());
            modelBuilder.Configurations.Add(new WordConfig());
            modelBuilder.Configurations.Add(new PictureConfig());
            modelBuilder.Configurations.Add(new LanguageConfig());
            modelBuilder.Configurations.Add(new RelationshipBetweenWordsConfig());
            base.OnModelCreating(modelBuilder);
            }

It looks like an ASP.Net app is using this code?

Looks like the app pool user is CL-xcsd-\medicallexicon_web. Make sure that user has appropriate permissions to the database.

For others that may find this… the default app pool user for IIS 7 is NETWORK SERVICE. If you have not changed the default app pool user, this is the account that needs permission in SQL.

Adding the user to SQL Server

1. Open SQL Server Management Studio
2. Find your database
3. Open the Security folder under your database
4. Right-click on the Users folder (inside Security folder)
5. Select New User…
6. Click the (…) button next to Login Name
7. Click the Browse button
8. Select your user and press OK
9. Press OK again back on the Select Login dialog
10. Give your user a User Name (e.g. medicallexicon_web)
11. Check the Database Role Membership checkboxes that apply (probably db_datareader and db_datawriter)
12. Click OK
