We have been running instances on Windows 2003 32 bit OS, now all machines are Windows 2008R2 64bit .
On 2003 I am seeing ASP.Net deadlocks, I cannot find the cause but I can watch the app pools consume more and more resources until finally they crash IIS.
The crash error says this:

On the R2 x64 my problem is getting DNN to run with UNC share. The variables in this environment are plenty, and I'm fumbling around to find the correct combination.
AppPool - trying to use the cross-application pool isolation; big problems with this on the UNC share. Our machines are in a domain, I assign the webhead to have permission on the UNC share but I can't assign the DefaultAppPool (from the webhead) not sure if this is my problem really because even using Network Services my site runs, but no images and no CSS shows up (running the site from the webhead).
(does anyone else find this editor as frustrating as I do?)
