For those of you who us the Microsoft Solution Accelerator “System Center Service Manager 2010 Dashboard,” but find the dashboard site presenting a “Cannot connect to configuration database” error, do this.
- Start > Administrative Tools > SharePoint Products and Technologies Configuration Wizard
- Complete the Wizard
- Reset IIS (or reboot)
This fixed my issue (Thanks Miles, superstar SharePoint guru for the tip). Mine was due to an MS .NET security patch (please see complete list in the graphic).
