Answer 1

You need to change permission for SharePoint_Config database, you can do as follows:

Login to SQL Server Management Studio under Database Engine using authorized login account. Expand Security tree and then r-click on Logins > New Login Click Search and then type your new login account (remember that you must use fully structure domain_name\user_name) After creating new login account, expand Databases tree, r-click on SharePoint_Config database and then select Properties. Click Permission setting, select account and then select permission you want to assign for account. Another Resolution

This error occurs because the SharePoint Timer service cannot log on to the SharePoint_Config database on the instance of Microsoft SQL Server that is used by SharePoint. To deploy Microsoft Dynamics NAV Portal Framework, Microsoft Dynamics NAV Setup creates a SharePoint Timer job through the SharePoint application programming interface (API). The SharePoint Timer must have access to the SharePoint_Config database.

To resolve this issue, add the logon account of the SharePoint Timer service as a user of the SharePoint_Config database. Give role membership to the account db_owner.
