UCMDB Server Connection Error to DataBase

Hello Experts, I am installing UCMDB 10.20 with DB SQL 2008. In the beginning of the installation, the wizard creates UCMDB Schemas Without problem. But When I try to open Browser Don’t Do it. In the logs, the error Says:

The user doesn´t connect to database but is the same user.

I already create the same user in the database and add to the server where the Database located is.

 

I Reinstall Database but now in the 2012 version, The Same Error Appears.

 

Do you have any ideas?

Thanks in advance.
