How to assign or give the permissions in the windows IIS server


Windows IIS(Internet Information Services), it is an extensible Windows web hosting server created by Microsoft for use with the Windows NT family, it supports HTTP, HTTP/2, HTTPS, FTP, FTPS, SMTP, and NNTP.


When you are working on the windows server you might across an issue while create or access a file or a folder, In such case, the main reason would be because you would not have adequate permission, let us look at an example where you will face such issue or error.


For Example: when you have just moved away from IIS6 on Win2003 to IIS8 on Win2012 for hosting ASP.NET applications and when you need to create and delete one particular folder in my application. After you have copied the files to the new server, you might face an error while deleting the file, the following error might be observed


Access to the path 'D:\WebSites\myapp.co.uk\companydata\filename.pdf' is denied.

When you are facing such errors you can resolve the error by granting the IIS_USER and NETWORK SERVICE and giving full access to the given permission  As shown in the below image


When you are giving/adding the user /group names we also need to add permission for the particular domain from the access control list.


Now let see what ACL or access control list means.It is the list permission linked to the object or group name and each of the permission entries is called as an Access Control Entry (ACE) It basically contains a permission associated with a particular identity. The most common permissions t in ACE are read, write, execute, and list folder contents.


Read / executes Permissions

It provides read and execute access to the file system object, respectively. The execute permission is applied to an operating system which can execute a particular application as the specified user.


List Folder Contents Permission

The list folder content permission, it is used for displaying the contents of a folder and to register file change notifications on a directory.


Full Control

The full control permission provides all access to the file system object. It is better to avoid giving full control, instead try giving read/write permissions.


Read permission

Read permission provides  read access to the file system object respectively


Modify Permission

Modify  permission when provided the username/group name will have access to modify the file  system object respectively


The IIS_IUSRS group replaces the IIS_WPG group. This built-in group has access to all the necessary file and system resources so that an account, when added to this group, can seamlessly act as an application pool identity.
