I have reviewed all posts related to my issue but nothing seems to work yet.

I'm working with SHP2010 and I'm getting the classic: <br/>
`Cannot connect to the configuration database` while trying to connect to the Central Admin.

The LOG says: <br>
`Cannot open database "SharePoint_Config" requested by the login...`

But I'm not being able to grant permissions to my user since the DataBase seems to be in a readonly state. (although I'm an Administrator)

More information:

 - I've tried it with all Administrator users.
 - All Windows Services are running (shpAdmin, shpTimer, all MSSQLSERVER services)
 - I've restarted all services listed above and also did IIS-reset.
 - I've tried to re-run Sharepoint Wizard and I'm getting same permission error.
 - When I open Sharepoint 2010 Management Shell as Administrator, I have the following message: `The local farm is not accessible. Cmdlets with FeatureDependencyId are not registered.`
 - `Psconfig.exe -cmd upgrade -inplace b2b -wait -force` gives me the same permission error.

Any thoughts? <br>
Thanks in advance!<br>
