BizTalk WCF-SQL Error: Microsoft.ServiceModel.Channels.Common.ConnectionException: Login failed for user

And yes, this is just another “Login failed for user” SQL Server WCF-Adapter related error. In the past, I wrote about a similar topic, BizTalk WCF-SQL Error:

• Microsoft.ServiceModel.Channels.Common.ConnectionException: Cannot open database “Database-Name” requested by the login. The login failed

This time, the error message, the cause, and the solution are slightly different. This time, while trying to communicate to a brand-new SQL Server server/database to insert the date into a table through BizTalk WCF-SQL adapter, I got the following error:

Microsoft.ServiceModel.Channels.Common.ConnectionException: Login failed for user ‘BTSHostSrvc’. —> System.Data.SqlClient.SqlException: Login failed for user ‘BTSHostSrvc’.

at System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection(DbConnectionPool pool, DbConnection.

In the event viewer, the message is pretty much the same:

A message sent to adapter “WCF-Custom” on send port “STAGING_BULK_SQL_WCf_SEND” with URI “mssql://SQLSRV/ /ESBAsync” is suspended.

Cause

Once again, sometimes it is not quite right; the cause of the problem is simple to diagnose, and the error message provides excellent insight into the cause.

This problem occurs because the user account that you used to access the database, in my case the BizTalk Host Instance Account, doesn’t have permissions to connect… to the SQL Server or SQL Server instance.

Just to be clear, this is not permission to insert or read, or even full permission to perform the operation on a specific database; that is entirely different – I check all of that, and the user has the correct access/permissions. What I forgot was to give access to connect to the SQL Server/SQL Server Instance.

Solution

To solve this issue, you must give access to the user, in my case, BizTalk Host Instance Account, to connect to the SQL Server, and for that, you must:

• Open SQL Server Management Studio and connect to your server.
• In the Object Explorer, expand the Security folder under the server.
• Right-click on the Logins folder and choose New Login…
• Add the username or group in the format Domain\UserNameOrGroup.

• Choose the Securables tab and make sure that you grant Connect SQL permission to the SQL Server/SQL Server instance.

• Click OK, and your user will be created and have access to connect to your SQL Server.
