Check database connection settings and user permissions.

To check the database connection settings:

1. On the Delivery Controller, open a PowerShell command window.
2. Type `asnp  Citrix*`.
3. Type `Get-AdminDBConnection` to generate the database server hostname.
4. Confirm that the server hostname is valid. If mirroring is used, confirm that the failover partner is correct. 
5. If hostname is not valid, need to null out currrent setting. Each service one has it's own connection string on every controller 
6. Set-[Admin]DBConnection $NULL (services needs to be nulled in the correct order, Delegated Admin, CentralConfig, ConfigLogging need to be last when nulled, and first when re-set)
7. Set-[Admin}DBConnection $connectionstring 

Connectionstring examaple: Server=SQLServer; Initial Catalog=CitrixSitenameSite;Integrated Security=True
