Version Information: Microsoft .NET Framework Version:2.0.50727.832; ASP.NET Version:2.0.50727.832

Actually, I just encountered the same problem in DNN 4.9.something.  The HD is a 500GB Sata2 with 286GB freespace.
What do you mean by "where the application resides"?
On windows, there is no Max Directory Size like there is on Nix.

Website is down.  This is strange & critical. Need help please.

Here is the fix to my problem... and probably the fix to Edgar's problem also.
The problem:  ASP disconnected itself from between DNN and the SQL Server.
Here is the Fix:
In a DOS box:
C:/windows/microsoft.net/framework/v2.0.50727/aspnet_regiis.exe -u  (which uninstalls ASP)
then
C:/windows/microsoft.net/framework/v2.0.50727/aspnet_regiis.exe -i (then reinstalls ASP)

This solution was provided to be by Mitch Sellers of www.iowacomputergurus.com.  He remembered this because early versions of DNN would frequently corrupt the ASP on the machine.
