sometimes the .net cache cause this problems.
shutdown iis and delete (rename) the cache.
somewehere within the following path:
C:\Windows\Microsoft.NET\Framework\v???\Temporary ASP.NET Files\your site name
restart IIS
clear the local browser cache (dont know why but nessesary at my notebook)

possible some Virusscanner or local firewall produce tis error.
(seen with symanted endpoint protection or MCAfee)

Before I start deleting things I want to be crystal clear.  In the Temporary ASP.NET folder I have citrix_pnagent and citrix_xenapp.  Delete 1 or both?

rename the folder. if your weninterface not work it is "citrix_xenapp" . You font this within the path of your website.
afrer renaming - start IIS  and opening the website , this folder are recreated and filled.

but you can rename booth. this cost you only some additional seconds at the next site-opening.
What does it mean to be "Always On"?

even after stopping the service, I can't rename them.  States in use by another program.  Any ideas?

stop the services
- web-publishing
- iisadmin
or use iisreset (stops and restarts the IIS services)

i am able to rename the folders.
