Grant permissions for that folder to the application pool. So you'd go to the C:\FileStorage folder in Windows and edit permissions, and add IIS APPPOOL\appPoolNameHere as a user, then give it full permissions.

Hope that helps.

EDIT

Step by Step Instructions...

-Open Windows Explorer

-Browse to your folder

-Right click the folder and go to Properties

-On the Security tab click Edit

-Click Add

-Under Locations, make sure it is pointing at your local machine, not a domain

-For the object name, enter below but replace MyAppPool with the name of your application pool...

IIS APPPOOL\MyAppPool

-Set the permissions to Full, or just add Write, or whatever you need.

would you please add little more details? – user1429595 Jun 05 '13 at 19:47
What part are you having trouble with? You know how to add permissions to a folder for a user right? You do the exact same thing, but you add it for the application pool. – Jim Jun 05 '13 at 19:51
the problem is I dont know how exactly how to add permission to a folder or IIS – user1429595 Jun 05 '13 at 19:53
My question is, how do you determine the name of your app pool? Is there a default name that can be used if you haven't specifically set one up? – B. Clay Shannon-B. Crow Raven Feb 06 '14 at 19:13

@B.ClayShannon To determine the app pool, you need to go to IIS, click on your website and then click on Basic Settings. The app pool should be displayed there. – Bat_Programmer Dec 16 '16 at 03:47
@Jim I am facing the same issue but when trying to access a network shared folder. Do you have any solution for this scenario? – Bat_Programmer Dec 16 '16 at 03:48
Maybe it is interesant for someone more: the default name is IIS APPPOOL\DefaultAppPool – Carlos Oct 31 '18 at 16:59

or you can repalce APPPOOL to the name of your server or computer and with the IIS_ISURS. example:

yourserver\IIS_IUSRS
