Yesterday, after the Windows Server 2003 running dotnetnuke 4.3.4 was patched with critical updates from Windows update and restarted, any attempts to load any dotnetnuke page result in 404 "This page cannot be found".

My investigation so far has led me to believe that it is a dotnet application pool crash.
