Hi,
Based on the error message, the login failed for user 'WREN\SVC-SC-OM12-DW', have you changed its password? Please make sure the account can access the SQL server where your data warehouse installed.
Or we may reset the account. And the article below should be helpful for changing password for data warehouse account:
