We are using DNN for our Intranet site. The site has been going down on a regular basis (weekly) and requires an IIS reset. Is there a process I can monitor or some other strategy in finding out the issue? I am guessing the problem is with the DB simply because it is driven by it... but I'm not sure. Thanks in advance!

check out the server logs for any hints, what caused the down state.

We've been looking at the logs and there aren't any clues to point us in the right direction. 
However...
When the site went down yesterday we looked at the logs on the DB and found that there were a bunch (30+) of NT AUTHORITY orphan connections. Once those were killed, the site came back up. I don't think those connections are from DNN... but I am not sure. Any ideas on that?

One time we "fixed" the site by changing the ASP.NET version on the virtual folder from 2.0 to 1.1 and back to 2.0... and most other times we have just done an IIS reset.

Look in the DNN Event Log. Do the crashes happen after an application restart?

About my reply earlier, the NT AUTHORITY connections are not related. Chasing ghosts! :)

The site does not crash after the IIS restart. It usually fixes it.

In the DNN Event log there were 2 errors right before the site went down. A Page Load Exception and a Module Load Exception. Here are snippets from that respectively:

Page Load Exception
