I had a SQL server suddenly stop working last night & can't get it going again. The service is running & will stop & start just fine but none of the apps (eg Sharepoint) can access their database & I can't use EM to access it.
When I use EM from the SQL server I get the error message "Invalid Connection. ConnectionOpen (Invalid Instance())". I have deleted & recreated the SQL Registration in EM to no avail. It is using Windows Authentication & I am logged into the server as an Administrator.
Any assistance would be appreciated as I'm currently at a loss as to what I should do next.
Thanks...TJ
