IIS7 folder permissions for web application - asp.net

I am using windows authentication without impersonation on my company's intranet website with IIS7.
Under IIS7, what account is used to access the folder which contains my web app using these settings?
Would it be IIS_IUSRS? Or NETWORK SERVICE? Or another I don't know about?

In IIS 7 (not IIS 7.5), sites access files and folders based on the account set on the application pool for the site. By default, in IIS7, this account is NETWORK SERVICE.
Specify an Identity for an Application Pool (IIS 7)
In IIS 7.5 (Windows 2008 R2 and Windows 7), the application pools run under the ApplicationPoolIdentity which is created when the application pool starts. If you want to set ACLS for this account, you need to choose IIS AppPool\<yourpoolname> instead of NT Authority\Network Service.

http://forums.iis.net/t/1187650.aspx has the answer. Setting the iis authentication to appliction pool identity will resolve this.
In IIS Authentication, Anonymous Authentication was set to "Specific User". When I changed it to Application Pool, I can access the site.
To set, click on your website in IIS and double-click "Authentication". Right-click on "Anonymous Authentication" and click "Edit..." option. Switch from "Specific User" to "Application pool identity". Now you should be able to set file and folder permissions using the IIS AppPool\{Your App Pool Name}.

If it's any help to anyone, give permission to "IIS_IUSRS" group.
Note that if you can't find "IIS_IUSRS", try prepending it with your server's name, like "MySexyServer\IIS_IUSRS".

Running IIS 7.5, I had luck adding permissions for the local computer user IUSR. The app pool user didn't work.

Worked for me in 30 seconds, short and sweet:
In IIS Manager (run inetmgr)
Go to ApplicationPool -> Advanced Settings
Set ApplicationPoolIdentity to NetworkService
Go to the file, right click properties, go to security, click edit, click add, enter Network Service (with space, then click 'check names'), and give full control (or just whatever permissions you need)

Working on IIS 7.5 and Windows 7 i couldnt give permission
APPPOOL/Mypool
IUSR and IIS_IUSRS permissions not working for me
I got to problem this way:
-Created console application with C#
-This appliaction using createeventsource like this
if(!System.Diagnostics.EventLog.SourceExists(sourceName)) System.Diagnostics.EventLog.CreateEventSource(sourceName,logName);
-Build solution and get .exe file
-Run exe as administator.This create log file.
NOTE: Dont remember Event viewer must be refresh for see the log.
I hope this solution helps someone :)

Read/Write permission for Web host application using IIS follow following step:-
1)Check the Application pool for the Site
2)Go to Application Pool and Check the Identity of the Site.
3)Explorer the Site and go to the main folder and right-click on that folder.
4)Go to Security Tab and click on the Edit button and then click on the user Identity and below you can see the multiple check box options which you want to provide permission for authenticated users after selecting the check box click on save.

Access to the path '0' is denied IIS 7

I have a web application developed in ASP.net 4.0 and hosted in IIS7(ProdServer).
In one of the pages I am creating a file and storing it in \someOtherServer\Storage\
folder.
when I log on to production server and hit run and \someOtherServer\Storage\
I am able to browse the folder.
When I run my ASP.net application I get the error
Access to the path '0' is denied.
Exception Details: System.UnauthorizedAccessException: Access to the path '0' is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
You will have to look at the identity of the apppool under which your ASP.net site is running and make sure that account has permissions to the resource on the other server.
To do this in IIS 7, do the following:
Open IIS manager and browse to the site where this is happening.
Right click on the site and select Manage Application -> Advanced settings.
The top most setting will show the name of the application pool you are running under. Most probably it is DefaultAppPool, but it could be something else too (preferably it should be something else).
Now cancel and click on the Application Pools node in IIS manager and right click on the application pool you saw above and select advanced settings.
Look at the Identity setting under process model - this might be ApplicationPoolIdentity. For you to access a resource on another machine you will have to run it either as NetworkService or as a domain account. I suggest you try the one and then the other. The domain account should be a service account which password does not expire (otherwise every time it expires you will have to retype it in here). Make sure that the domain account has access to the shared resource on the remote server.
Hope that helps someone.

401.2 Error in ASP.Net 2.0 on IIS 7.0 on Windows 2008

My "Hello World" c#.Net application works fine on my local Windows 7. Moving to our server I get 401.2 error.
Here what I have done (following advices in some forums):
Changed the Anonymous authentication use to application pull user
Created a new application pull
Created a new Windows user with access to application folders
Set the authentication of the application pull to that user
Set the application pull for my application to that application pull
Please note that:
I receive the error both from within the server and outside
I receive this error from all the browser I tested: Chrome, IE 9.0 and Firefox
An html file in the same folder is visible
What am I missing?
Thanks,
Asaf
You don't need to create a new windows user. I know you've said what steps you've done, but I'm going to highlight what I do each time I add a new site.
Set the Identity of the Application Pool to
ApplicationPoolIdentity.
In the website, set Anonymous Authentication to Enabled. Click
Edit on the right and set the Authentication Credentials to
Application pool identity.
In the website, again, choose Basic Settings on the right. Click
the Connect As.. button and make sure Application User is
selected.
Give the appropriate access to the folder on your hard drive(s); i.e
Application Pool name = hello.com, the user is IIS
AppPool\hello.com.
I think your issue is that you haven't given the folder permissions for the Application Pool User. I think you've incorrectly given them to an unneccessary Windows account.
HTH
Do you have the correct version of .NET installed on Server? Also you need to register ASP.NET in IIS - c:\windows\Microsoft.NET\framework\v2.0.50727 (or v4.0....)
aspnet_regiis.exe -i
and after restart IIS with iisreset in command line

HTTP Error 401.3 - Unauthorized

I am getting this errror in my newly created website in Windows 7 and IIS 7.5. I created an SSL certificate and done binding new website.
HTTP Error 401.3 - Unauthorized
You do not have permission to view this directory or page because of the access control list (ACL) configuration or encryption settings for this resource on the Web server.
Earlier when I created the website, I selected 'application user(pass through authentication)' in 'Add Website' dialogue. and when I click "Test Settings ..." button, I get this error message:
The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that \$ has Read access to the physical path. Then test these settings again.
Please suggest solution to this.
Thanks.
I had the same issue, ensured my DefaultAppPool was running under ApplicationPoolIdentity and the DefaultAppPool had permissions to the folder, but some files still didn't load.
Turns out my problem was that the anonymous authentication user was set to someone else instead of ApplicationPoolIdentity
Screenshot
Make sure that application pool of your website and website both are running under the same identity. Then make sure that this identity has required permissions on the virtual directory. I had exact same issue and above two checks fixed it.
IIS 7 also creates "IUSR" as default user to access files via IIS. So make sure user IUSR has read access to files/folders.
How to check if IUSR has read Access? Right Click -> Folder -> Properties -> Security Tab See if IUSR is in Group or user names list, If No.
Click Edit -> Add -> Advanced -> Find Now -> Select IUSR and click OK -->click Apply
The below worked for me. I did not set up an SSL, just a new website within IIS. Upon doing so I was immediately unable to access the website with this error message.
When I created the new website, a new Application Pool was also created. The Identity of this Application Pool was set to ApplicationPoolIdentity. As mentioned by Suhas, the Application Pool of the website and the website itself must be running under the same identity. (I do not know how to check the identity of the website, but the Application Pool's Identity can be checked by going to Application Pools and looking at the Identity column). The default Application Pool name is DefaultAppPool.
I added permissions to the site (right click the site name -> Edit Permissions -> Security -> Edit -> Add), linking the site to the DefaultAppPool object, which in turn gives the site access to the default user and it's settings. (The default user is created when IIS is installed. Read more about this in Microsoft's docs).
I thought this would be all that's needed to obtain access, but this is incorrect. The website's Application Pool must also be set to DefaultAppPool. This can be done by right clicking on the site -> Manage Website -> Advanced Settings -> Change the Application Pool value to DefaultAppPool.

Asp.net Account in windows 7?

I want to authorize the asp.net account to access some folders in my project.
However, I get this error::
System.UnauthorizedAccessException: Access to the path 'D:\ProgramingPart\FromYamn\WebExercise\WebExercise\AccordionImgs' is denied.
I am using win 7 so what is the name of the asp.net account that I should use?
This depends on a couple of things:
What identity is the application pool running as?
What IIS authentication method are you using?
If you are using IIS7 in Classic Pipeline Mode, what authentication method are you using for ASP.NET (see your web.config file).
Try running visual studio as Administrator.
Under Win7 the default IIS user is ApplicationPoolIdentity. This is somewhat confusing as it's not a real user account. In order to adjust the permissions you need to drop to the command line first and issue
icacls D:\ProgramingPart\FromYamn\WebExercise\WebExercise\AccordionImgs /grant "IIS APPPOOL\DefaultAppPool":(OI)(CI)(RX)
From there you can return to explorer and edit the permissions using the properties tab for the directory. Or you can simply type "IIS APPPOOL\DefaultAppPool" in the add users field in explorer, but I have a preference for icacls myself :)
Probably you want to add the permissions a bit further up the tree. In real shared hosting scenarios application pools tend to get their own, full user accounts, but Server 2008/Win7 added the app pool user so pools can be created, isolated without having to do that.
This worked for me:
On the folder of your application, which might be something like:
C:\Users\YourName\Documents\YourSite
or
C:\inetpub\wwwroot\YourSite
Right-click the folder, choose Properties, go to the Security tab.
You need to add IIS_IUSRS to this list, and probably give full control.
Then, in IIS Manager, assuming you've set up your project folder as an application here, click on your folder/application. Then click the Authentication option. Right click the Anonymous Authentication, and check the user identity. Mine is IUSR.
Go back to your folder security, and add this user, with full control too.
Hopefully it works now!

Proper setup for IIS7.5 machine account for anonymous Web site access

Using IIS 7.5, IIS_IUSRS is supposed to be the account to use. I get '401 - Unauthorized: Access is denied due to invalid credentials' error. If I add an EVERYONE account with Read, it works. But rather not have Everyone account. Any idea why IIS_IUSRS does not work? It has Read access. Anonymous Access=enabled. Specific User=IUSR
As a side, on the Basic Settings... for the site, Test Settings button says 'ok-on Authenticate' but Authorization 'cannot verify access to path'.
In IIS 7.5 this has changed from being an IIS_IUSRS account to being a user under the IIS AppPools top level windows group
if you create an application pool called
www.mysite.com
then the sites default created user account that it runs as becomes
IIS AppPools\www.mysite.com
Check the following Microsoft Doc under "Securing Resources" to see more
http://learn.iis.net/page.aspx/624/application-pool-identities/
Under the 'Securing Resources' section listed here:
Open Windows Explorer.
Select a file or directory.
Right click the file and select "Properties"
Select the "Security" tab Click the "Edit" and then "Add" button
Click the "Locations" button and make sure you select your machine. Enter "IIS AppPool\DefaultAppPool" in the "Enter the object names to select:" text box.
Click the "Check Names" button and click "OK".
Substitute DefaultAppPool with the name of the application pool you created/used when adding your site to IIS. This IIS AppPool (not IIS AppPools as of iis 7.5.7600 on Windows 7 pro) group is a group of virtual accounts that you will not see when performing a normal account search on your local machine or via a directory service.
