I don't really know what to do. I was trying to get some bcs working, and because they were not, I've decided to restart the server.
After it restarted I was unable to go on any site / page or on the central administration. I had this message :
[WebPartPageUserException: Cannot connect to the configuration database Error]
Microsoft.SharePoint.ApplicationRuntime.SPRequestModule.EnsureInitialize(HttpRequest request) +740
Microsoft.SharePoint.ApplicationRuntime.SPRequestModule.BeginRequestHandler(Object oSender, EventArgs ea) +164
System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +80 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +171
I first tried to do a open sql server manager, and discovered that I couldn't connect to sql server neither. After some researches I found how to restart sql server manager. And know it's okay, I can connect to sql server via sql server manager. But I still can't connect to my SharePoint server via browser.
I tried to do an iisreset, but it doesn't work. So if you have any idea on how I could resolve this issue, I would be really thankful.
