I assume this is an IIS error, as this doesn't happen if I run the project on my local machine.
I have my stylesheets at ~/Content/css
Any files in that directory won't load on the page, and when I navigate to them directly, I get a server error:
401 - Unauthorized: Access is denied due to invalid credentials.
You do not have permission to view this directory or page using the credentials that you supplied.
This only happens with that directory, I have no problem accessing any other files. Is there something I need to do in IIS7 to stop this?
Open IIS and select site that is causing 401
Select Authentication property in IIS Header
Select Anonymous Authentication
Right click on it, select Edit and choose Application pool identity
Restart site and it should work
It is likely that you do not have the IUSR_computername permission on that folder. I've just had a quick scan and it looks like you will find the information you need here.
If that isn't the case, are you prompted for your username and password by the browser? If so it may be that IIS is configured to use Integrated authentication only, as described here.
Open IIS
select site where you are facing the problem
Select Below
- Right click on Anonymous Authentication and click on edit and follow below
You do not have permision to view this directory or page using the credentials that you supplied.
This happened despite the fact the user is already authenticated via Active Directory.
There can be many causes to Access Denied error, but if you think you’ve already configured everything correctly from your web application, there might be a little detail that’s forgotten. Make sure you give the proper permission to Authenticated Users to access your web application directory.
Here are the steps I took to solve this issue.
Right-click on the directory where the web application is stored and select Properties and click on Security tab.
Click on Click on Edit…, then Add… button. Type in Authenticated Users in the Enter the object names to select., then Add button. Type in Authenticated Users in the Enter the object names to select.
Click OK and you should see Authenticated Users as one of the user names. Give proper permissions on the Permissions for Authenticated Users box on the lower end if they’re not checked already.
Click OK twice to close the dialog box. It should take effect immediately, but if you want to be sure, you can restart IIS for your web application.
Refresh your browser and it should display the web page now.
Hope this helps!
You need to check the folder permissions on your server and check that the account that you are using to run your application has access to that folder.
For me the Anonymous User access was fine at the server level, but varied at just one of my "virtual" folders.
Took me quite a bit of foundering about and then some help from a colleague to learn that IIS has "authentication" settings at the virtual folder level too - hopefully this helps someone else with my predicament.
In our case it was Windows-integrated authentication specified in the app's web.config
BUT the windows-auth module was not installed on the IIS machine at all.
Just adding another possible reason.
Another simple fix I found was to delete the local IIS site (from within IIS Manager) and then re-create the virtual directory from the "Properties" of your web project in Visual Studio.

I have setup a application in my IIS7 that uses .NET Framework 4.0 (runned by NetworkService) but when browsing the site I get this:
Access is denied.
Description: An error occurred while accessing the resources required to serve this request. You might not have permission to view the requested resources.
Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists). Ask the Web server's administrator to give you access to*
I have tried to give NetworkService full permission on the folder that holds the website (the one that the web application in IIS is pointing against) but I do still get the access denied?
Why?
I gave access to "IIS_IUser" but instead it should be "IUSR". That solved the problem.
For me, nothing worked except the following, which solved the problem: open IIS, select the site, open Authentication (in the IIS section), right click Anonymous Authentication and select Edit, select Application Pool Identity.
I had the same problem, I enabled "Anonymous Authentication" but it still did not work.
So I also ENABLED "Forms Authentication" Then it worked without any problems.
OS : Windows 7 & IIS 7
If you still have permission denied after adding IUSR & NETWORK SERVICE.
Add also IIS_WPG. The addition of this last user solved my problem.
For people who can't find those users:
when you're trying to add a user in security of the folder (properties of the folder), click on "Advanced" of the window "Select Users or Groups". Change the location to the computer name then click on "Find Now". You'll find those users in the list below.
If you're using Anonymous Authentication, IIS 7 will use the "IUSR" account for directory access (unless you've set it to use the app pool identity. If you haven't granted IUSR sufficient permissions on your site's folders and files, you'll get this error
For me in windows 7 it started to work only after I gave 'Read & execute', 'List folder contents', 'Read' permissions to site folder for both users
IUSR
NETWORK SERVICE
Tried most of the solutions here, but no luck. What worked for me was adding "Everyone" to the security permissions. Properties -> Security -> Edit -> Add -> Everyone. The given defaults were enough for me to regain access.
In the near future, I should probably figure out what credentials are being sent to the server so that I can give proper permissions. But I hope it helps someone!
In the Authentication settings for APP itself (IN IIS), see if you have anonymous enabled.
We need to create a new user ComputerName\IUSR by going to the website folder-->Properties--->Security--->Edit-->Add and give read access. This would work definitely.
This solution is for IIS7
I went round and round on this and it turned out to be improperly set default page. Hope this helps someone else avoid an hour of wasted time.
In my case running c:\windows\Microsoft.Net\Framework64\v4.0.30319\aspnet_regiis.exe /i resolved the 403 access denied issue.
Checking the Application Pool Identity in Anonymous Authentication and enabling Forms Authentication would solve problem for access denied error. 😁
After some thinking and a lot of of trial and error I found out that this error occurred because part of my web.config was encrypted and for some reason the key was no longer valid.
Re-encrypting the config section solved the issue.
After watching this tutorial :
https://www.youtube.com/watch?v=RbrZbHpXBTE&list=PLp1Emx1rT4z9YWLDXBjUwBb130qv2Zq2x&index=4&ab_channel=LearningProgrammingTutorial
I had the same problem using RDP ( windows server 2016 Datacenter )
i followed the tutorial above & enbaled my directory browsing options from the IIS internet infromation services manager.
what you want to do is to access your IIS manager , you can check out the tutorial above to learn how to access IIS manager if you have trouble acessing there , it was useful for me that's why I'm sharing then ... go to :
you should gave access to IUSER
( or application tool identity , depends or what you want to work with )
and your problem would be solved! :)
Also you need to check your firewall and TCP settings , if ping between two machines didn't work for you , you can check this out :

It was due to WWWRoot directory security issue.
Simple solution is, Just copy applicatio folder to some other drive, Instead of "C:\Inetpub\wwwroot"
and then create a virtual directory for this new path. That's it.
If the IUSR user is already specified in Authentication and you're still getting this issue, it could be that your Directory Listing isn't enabled. Be sure to check that. That was the case for me.
This is what happened to me:
Get - Post is ok. Working well.
When I try to use Options verb, the server return error like that.
Then, beware with urlScan
I add OPTIONS verb to urlscan configuration .ini file, then everything works well.
To check if urlscan is installed or not, open your iis manager, and open ISAPI FILTERS url scan should appear at the list.
I was also facing the same issue,
Everything was normal all the rights were given to the user and for folder as well.
After many research i found that the wwwroot (Source code folder) was shared with some other user.
I stopped sharing and it worked like a charm.
I was facing this issue after pulling from remote master and adding to the appsettings on web.config.
I solved it by enabling Windows Authentication:
Click on the project and press f4
Make sure Windows Auth is enabled:
I have been trying to configure a small website on a Windows Server 2008 running IIS 7. Unfortunately, when trying to load the website I keep getting the error: Server Error 401 - Unauthorized: Access is denied due to invalid credentials.
The permissions on the website folder include read, write, and execute for user ASP.NET v4.0. I even clicked "Check names" before adding the user to folder, to make sure that I spelled everything correctly. But the error continues to show. Also, I noticed that everything works okay if I add "Users" to the permissions for the folders containing the website, but I don't see why this should be necessary. I only want to give ASP.NET v4.0 access to the folder.
Some other noteworthy points include that I'm using the ASP.NET v4.0 application pool, that the managed pipeline is integrated, and that load user profile is set to true.
If anyone has any ideas, I'd appreciated the help. I'm stumped!
EDIT: Does it matter that the website is on the d: drive? I just assumed this wasn't important...
I find I always need to give IIS_IUSRS access.
I'd recommend you to use the Process Monitor to detect which user is actually accessing the file.
Here you'll find an explanation about how to achieve that.
Open IIS7 on the server. Highlight the site, and double-click on the Authentication icon in the Security Section. Check that Anonymous Authentication is enabled.

I am trying to FTP to a new FTP site I setup with IIS 7.0 for the Windows Server Web (64-bit) edition. But I get the above error when I try to login to this site. But I can login to my other FTP sites.
Also, when I select this website from IIS Manager, the FTP section does not display in the middle section although it does display in Action panel. And I cannot successfully login to this FTP site either.
I have checked and I have Log on locally selected. I do not have allow only anonymous connections. I have Access this computer from the network selected.
I restarted my IIS and FTP services also.
The one different thing I noticed about this website in IIS different from the other site that has FTP working is that this one there are 3 virtual directories beneath the site. And that when I click on any one of these 3, then the FTP strip does appear in the center pane. Make sense?
How can I debug cause of this error? Any SW tools I can use?
Have you tried logging in from the FTP server? If you do this, and have "Show detailed messages from local requests" enabled under FTP Messages, then you'll get a clearer idea as to why the login if failing. In my case I got the following message (I am using IIS Manager Users, and Passthrough authentication)
530-User cannot log in.
Win32 error: Access is denied.
Error details: Filename: \\?\C:\Windows\system32\inetsrv\config\redirection.config
Error: Cannot read configuration file due to insufficient permissions
To solve this I gave the NETWORK SERVICES user read only access to the config directory specified in the error message. I'm not 100% sure this is the right thing to do, but it certainly fixed this issue for me.
in my situation, I was missing Role Service FTP extensibility, which is actually allows IIS Manager Auth.
This is pretty tricky, as you could allow IIS Manager auth, but still it would not work until you have not installed FTP Extensibility
In my case I forgot to enable the Basic authentication
There seem to be many different possible causes. In my case, I was unable to login with the plain "username" with the same error as mentioned.
It was solved when I logged in with ".\username" instead.
For some reason the FTP client was trying to login with a domain account, while I just wanted to login with a local computer account.
Hope this helps someone.
Try submitting your credentials in this format:
UserName: Domain|Username
Password: secretSquirrel
I had the same problem, I removed the FTP site and followed this:
http://www.iis.net/learn/publish/using-the-ftp-service/configure-ftp-with-iis-manager-authentication-in-iis-7
Prerequisites - I set the permissions on the folders using the 4 command samples but this did not alone fix the issue, so I cannot in good faith say this step is needed, but it is what I did and it now works.
CONFIGURE THE IIS MANAGEMENT SERVICE AND ADD AN IIS 7 MANAGER -
Just do step 4, removing the existing user first and then re-adding them.
Creating a New FTP Site and Configuring an IIS 7 Manager Account -
All the steps here
CONFIGURE THE FTP SITE TO USE IIS 7 MANAGER AUTHENTICATION
All 12 steps here, including the "administrator" setting in step 5.
Then it started working for me, I am guessing when I did this without a guide I skipped something simple.
In My case I have made that user a member of IIS_IUSERS.
Using IIS Users.
Do not isolate users -> User name directory was working fine. Users started in the right folder.
When I was switching to Isolate Users -> User name Directory I had the following error:
Response: 530 User cannot log in, home directory inaccessible.
Win32 error: The system cannot find the path specified.
For some reason, you need to add the LocalUser virtual directory that points to your root.
It has to be that exact name and it's case sensitive.
That worked for me.
Per this knowledgebase article, you would need the log on locally privilege enabled.
http://support.microsoft.com/kb/200475
I had the exact same error. In my case, I was using a local user defined on the server running FTP. The username was very short (3 characters). I could "run as" this user on the server, confirming that Windows was Ok with it, and allowed it to authenticate. But when testing FTP, it would return User cannot log in.
Solution? I renamed the user to be longer (4 characters). Of course, updated its name under Authorization as well. Then FTP worked. Hope it helps someone!
For me, I've configured the IIS as per usual procedure properly. The anonymous authentication was working but specific user are not.
because, the user accounts were created in IIS. Actually it was also supposed to be created Windows local accounts.
Then it worked.
Please Check the security of folder which is use that ftp .
see if the user or group you select for that ftp is associate with security of that folder .
In my case I had to remove domain from user.
So, your user should be like username, not like domain\username.
Hope it helps to somebody.
For some reason my user was "locked". So I could "unlock" it at local user manager (computer management). Now it works fine. I hope it helps.
I would recommend checking FTP logs first. The status code will give you more information about the issue. Here is the explanation of the status codes: The FTP status codes in IIS 7.0 and later versions
I had this issue because my IIS didn't support passive mode. After entering data in FTP Firewall Support module, the issue was solved.
More scenarios from this post 530 User cannot log in, home directory inaccessible
Authorization rules. Make sure to have an Authorization rule that allows the user or anonymous access. Check “IIS > FTP site > FTP Authorization Rules” page to allow or deny access for certain or all users.
NTFS permissions. The FTP users (local or domain users) should have permissions on the physical folder. Right click the folder and go to Properties. In the Security tab, make sure the user has required permissions. You can ignore Shared tab. It is not used for FTP access.
Locked account. If you local or domain account is locked or expired, you may end up seeing “User cannot log in” error. Check local user properties or Active Directory user settings to make sure the user account is active.
Other permission issues. The user account may not have “Log on locally” or “Allow only anonymous connections security” rights.
I spent long time looking for a solution, I've tried every shared answer on the internet and nothing could solve the issue. It is an issue I was ignoring for years and I never could fix.
Ok, I've Plesk installed and I'm not sure if it has some effect on IIS FTP to do the following behavior ...
Using Process Monitor tool, and making ftp login request and watching the tool and doing your investigation using this tool, you can get a hint about the REAL reason of the problem.
For me, I found out that IIS FTP was trying to access the ftp folder from a path DIFFERENT than the actual ftp path I've set, I do not know why, but maybe Plesk has some effect on this.
The actual ftp path is
C:\inetpub\vhosts\zidapp
The path that IIS FTP was trying to access DURING the login process is
C:\inetpub\vhosts\Servers\7\localuser\zid_app_ftp_user
I fixed the issue by creating a folder link from 'actual' folder path to the path IIS was trying to access - using the tool mklink tool
CMD command
mklink /d C:\inetpub\vhosts\Servers\7\localuser\zid_app_ftp_user "C:\inetpub\vhosts\zidapp"
I've fixed the issue that way, so wen FTP is trying to access the folder from the wrong path, it is now goes to the correct one.
Please note doing folder shortcut wont work for this, you need a link like linux, not a shortcut ...
I hope it will help you :)
You can check the reference account you are using to log in.
Mine happened to be locked out causing the 530 error.
I was looking for the the trick to resolve that error (google, stackoverflow.com etc) and every nothing works.
I need to dynamically create an .aspx file via the asp.net application.
What I've done to try fix it:
1) In the folder's Properties -> Security, I've added IUSR_TONY and also IIS_IUSRS and allow them the Full control to the folder. Just to check if that will help. Nope, it won't.
2) in the IIS Manager, I tried to change the Application's Pool Defaults Identity (based on that) I checked all options, with no success
I don't know what to do more to fix it. Any ideas ?
Directions for IIS 6
You need to change the 'Home Directory' permissions with IIS Manager.
Open Properties on the website. Select the 'Home Directory' tab. Check the 'Write' checkbox to enable write permissions.
If you are set on doing this, I would suggest only enabling write on a particular directory and not the entire website. Changing the permissions for a single directory is the same as above except instead of selecting Properties for the entire website, choose Properties for the directory where you will be creating files.
Directions for IIS 7
Open Internet Information Systems (IIS) Manager
Expand the site you want to modify (hit the plus next to the name)
Right-click the directory where you would like to be able to write files and select Edit Permissions
Click on the Security tab
Click on Edit... under the group and users list
Select IIS_IUSRS from the "Groups or user names" list and add make sure the Allow checkbox is marked for Write.
I know this sounds a lot like what you did in 1) of your question but I'm guessing you may just edited the permissions through Windows Explorer rather than IIS Manager. Let me know what error(s) you see if the steps above still don't work for you.
I tested writing a file to disk using an example from aspalliance.com and it worked great when I granted IIS_IUSRS write permission to the output directory and stopped working when I removed the write permission.
Please state your operating system and version of IIS.
You need to grant access to the account that is running the app-pool in IIS. It is usually NT Authority\Network Service, so try granting full control to that account.
However, if you are using windows integrated security (and have impersonation=true) on your website, the user that must be granted access, is the user requesting the page.
Finally, I really want to discourage you from making a blog system that creates aspx files on the fly. It's simply not the way to do it.
This application is using windows integrated authentication in IIS. No anonymous login.
It's also using an application pool defined to log on with a domain user.
If a try to browse any page, it pops up the username and password dialog box and even though I entered a valid user (including the domain administrator) it doesn't log on into the app. I keep getting the username/password dialog. If I logon locally (in the IIS box), it works OK.
Also, if I change the application pool to use Network Services, it works OK.
The domain user is already a member of the local IIS_WPG group in the IIS box.
Am I missing something here?
If you use a domain account for the Application Pool you have to run a series of scripts on the domain controller. So, apparently it's not recommended to use a domain account, rather a local server account. Microsoft has this issue documented on a case:
http://support.microsoft.com/default.aspx/kb/871179
I suspect the NTFS file persmissions on the .aspx files don't allow the users you are logging in as the needed access to read/execute them. What are the file permissions on the files you are trying to view? What do your authorization and authentication elements in web.config look like?
This sounds like it's related to the privilges assigned to the domain user. i.e. whether they, or indeed the server, are permitted to impersonate the user that is logging in. Or, something regarding "Trusted for delegation" in the server's settings in AD. Either way, you'll probably get a better response on serverfault =)
Try entering the same user of the appPool as the anonymous user (Web Site Security tab)
I had the same user/pwd Popup problem in Svr 2003.
I solved it by CHECKING ANONYMOUS ACCESS in directory security of DEFAULT WEB SITE.
It promps you if you want to also affect your sites you click OK.
That did it.
