Had to reset virtual directories on our Exchange 2010 server and now get runtime errors on all virtual directories we attempt to access. Have verified the dill file paths are correct in web.config. Event Viewer shows the following errors:

What build level of Exchange 2010 are you on, what is the host OS and what is the latest version of netframework that you have installed?

Looks like the app pools are wrong.
How did you reset the virtual directories? Did you use the manual Shell method, or did you use the wizards in EMC?

Fixed the issue doing the following:

Browsed to:C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files

change the owa directory to owa.old

replaced OWA web.config with copy from another virtual directory

restarted IIS


Works now
