Hello,
I have 3 instances of DNN on a local machine, periodically one of the sites gives the message:
'DNN Error
Unable to connect to the database' (or words to that effect)
Each time I check the following:
SQL Server (Express) service is running (even though this would effect all web sites)
That the web site's Application Pool is running.
Under IIS, ensure that the desktop modules directory hasn't become a virtual directory which Visual Studio seems to do randomly and occasionally.
In the end, I have to reboot and each time that solves the issue.
So does anyone have any suggestions to what would cause this issue?
What else is there to check? So it must be something relating to the specific instance of DNN on each occasion.
There isn't one site that always fail, each one seems to take it's turn.
I think I previously posted a similar question, on that occasion it turned out to be a virtual directory created on the desktop modules directory.
Best Regards,
Steve
