With a clean installation of Windows Server Standard 2022 as a VM on RedHat8, the IIS does not permit the Administrator to make any changes to a web sites file sharing permissions. In fact, it isn't possible to start with the defaults, then simply "Share" them.
The workaround is to use File Explorer to locate the directory you wish to share, then modify from that point without an issue.
Use the File Explorer to locate the web site directory under C:\inetpub\wwwroot\the_directory_to_share and change the permissions there.

I'm fairly new to developing with ASP.NET and in general. I have created a simple data-driven web application that will be used to display images the colors of which will be changed depending on certain criteria. I used Visual Studio 2019 to create it. When I test/run it from within VS 2019 using the "play" button, it runs perfectly and the page opens in my browser just as you would expect.
My issue is that I'm trying to deploy it to the IIS and host it from my machine here at work, so others can access the pages. I have published the application to a local file on my C:\ drive. I then open up IIS Manager and create the website by pointing to that local file. Now, when I choose to browse that site from the IIS manager, at first I was getting an error saying that access is denied.
Then I followed the instructions to configure the security on that local file folder to allow IIS_USRS to access the file, but when I run it, I just get a page that tries to load indefinitely.
What am I doing wrong? If I point the IIS Manager to the files after saving them to a location on my company's network, I again get the access is denied error.
Do I understand it correctly that IIS needs permission to access the files? If so, how do I configure it that way other than what I already tried? If I need to provide further information, please let me know. Thanks so much for your support.
I previously made my "Web Applications" type of projects inside some individual directories
and have been making "Web Site" types (based on visual studio's project types") inside IIS.
Although It should be a repetitive task but I want to know the most usual needed steps for doing so
What I need :
Access to the media with absolute paths
As an example
I placed my project inside "IIS Root folder/ProjectBase/Project"
and convert that to Web Application via IIS.
It seems that I couldn't access to my stored media files within the Project Folder.
What is the exact problem in this case ? Is it related to folder permissions of the "Project Folder" ?
Also should I make the "ProjectBase" Folder also a virtual directory ?
the program is running via cassini,
At first I want to have access to my Project based files via "absolute paths"
As a conclusion
Having "Web Application" Type running with possibility to access to its files via absolute paths.
It should be an easy task for the Pros, but, anyway I'm in hurry and needed good-fast advice.
thanks in advance
Could be a file permissions issue. You can resolve that by going through IIS and setting the permissions on the folders. Grant read/write to the IIS user for that machine. If you're actually writing anything back you may need to grant access to Network_Services as well.
Also you can look at adding a virtual directory to the website in IIS and point that to the actual physical directory on the box. That has solved some file access issues for me in the past.
Our asp.net app writes errors to a text log file in the web sites root folder. This has lead to all sorts of permission problems, different flavors of IIS and windows allow different things by default.
So what I am wondering is there a location somewhere in Windows where all types of users can write a file without any extra permissions that will also work for all IIS and flavors of windows?
I am thinking of the ApplicationData folder, but did this exist in Server 2003 ?
Thanks,

The easiest solution would be to use the App_Data subfolder of your web application for this. By default it's not viewable from the web, so Internet clients won't be able to read the logs.
Depending on your deployment method, you might have to change the permission to allow write access to this folder (to the user under which your web application is running).
Alternatively, there is a place where every user can write to: It's that user's temporary folder, which you can access through Path.GetTempPath. This, however, does not sound like a suitable location for log files.
You should always first think about wwwroot folder (%systemdrive%\inetpub\wwwroot) because it has the required permission.
The permission you need is to set a full control for IIS_IUSRS
Edit: you can simply give Everyone Full Control (not recommended at all) but this solves most of ntfs permissions issues with IIS
We're having trouble migrating our ASP.NET applications to Windows Server 2008 R2 x64 and IIS7.5. The problem is that our ASP.NET apps write log files, and these log files are not being written. The only way the apps write their log files is if I'm logged into the server as the local Administrator user or if I right click and run IE as Run as Administrator, neither of which is an acceptable solution for us.
Our platform is:
Windows Server 2008 R2 x64 (UAC setting is the default setting)
IIS7.5
ASP.NET 4.0 (using Windows authentication and impersonation, both on in web.config)
Our app gets installed to:
D:[appname]
[appnameWebSite] (all the .aspx, .dll, etc. files are in here)
\Log (the app tries to write the log file to this folder)
On the server:
Created new App Pool (name: [appname], .NET 4.0, Managed Pipeline Mode: Classic, Identity: ApplicationPoolIdentity, Load User Profile: False, all other properties are the defaults)
Created IIS application pointing to D:[appname][appnameWebSite] and added it the the new App Pool (Full trust level)
Have a domain user in local Administrators group
With all the configuration and default settings listed above, the ASP.NET app will not write the log file. The app appears to work fine in the browser, but no log.txt file.
To try to "fix" this issues, we've tried many things:
Tried Application Pool setting: Managed Pipeline Mode: Integrated
Tried Application Pool setting: Identity: NetworkService
Tried Application Pool setting: Identity: LocalSystem
Tried Application Pool setting: Load User Profile: True
Gave Users group full control to file system for our application folder structure (tried appname folder, tried Log folder only, tried appnameWebSite and Log folders only)
Gave IIS AppPool[appname] (matching the new App Pool) user full control to file system for our application folder structure (tried appname folder, tried Log folder only, tried appnameWebSite and Log folders only)
None of these things helped. Again, the app would run fine, just no log file created.
As mentioned above, the only way that the log file is created when the app runs is if we log into the server using the local Administrator account (which makes sense since he's a super user) or if we run IE as administrator and elevate privileges.
Any suggestions? Help? Questions?
Thanks!
I tried granting every permission possible and still wasn't getting any log files. Finally I came across this which suggested changing the ownership of my logfiles directory. I checked, and the directory ownership was set to SYSTEM. I changed it to Administrators and applied the change recursively. I bounced IIS, hit a webpage from the site in the browser, and now I have log files. Hooray!
Note: the thing that tipped me off was checking the System event log. I was getting 15006 errors saying "Owner of the log file or directory C:\inetpub\logfiles\W3SVC1\some.log is invalid. This could be because another user has already created the log file or the directory."
Well, after days of trying every IIS option, user and group accounts, file system permissions, Process Explorer, etc., I think we got it working:
We reset all our IIS app pool and web site settings to their default values
We also reset the folder/file system permissions on our Log folder to the default settings
Then we turned off Internet Explorer Enhanced Security Configuration on the server
And success! The log file is written as expected no matter what user is using the ASP.NET application, and no matter if they're running it on the server itself or from a workstation.
I don't know if turning off Internet Explorer Enhanced Security Configuration on the server is the "correct" thing to do or if it violates any best practices, but it seems to work for us.
Does anyone have anything to add?
I struggled with this one for a while. The ApplicationPoolIdentity is a member of the Users group and the Users group has limited access.
From Explorer, right-click on the folder where you are trying to write and go to Security. Click the Advanced button. you will see that Users have Read and Execute permission and the Users group may or may not have Special permissions. If not, Click on Change Permissions and give Users the ability to Create files / write data and Create folders / append data. This is restricted to this folder. I usially use a subfolder so that I not provide write access to my whole website.
Try creating log files again. This is the only permission that I needed to set to make it work.
For me the trick was giving write access for SYSTEM and Administrators not only to the log folder itself, but also every folder in the path. This is not how permissions usually work in Windows, but IIS appears to be really rather particular about it. Not that there is a good reason to remove these two from the ACLs to begin with.
If you suspect this to be the problem, check the Event Log under Windows Logs / System. This issue manifests itself as an Error entry from source HttpEvent, and reads "Unable to create log file C:\path\to\logs\W3SVC1\u_extend1.log. Make sure that the logging directory is correct and this computer has write access to that directory."
P.S. This is true for IIS 10 but may apply to other versions too.
I've just installed windows server 2008 r2 along with visual studio and dropbox. I'm using it as a VM for development and dropbox helps me keep my files in sync with other machines.
I've got my site set up in IIS but I'm getting an access denied error when trying to view the site. I've had this before and to get around it in the past I've gone through and added the IIS_User account to the list of permissions to read/modify the files. I assume because the file's have been copied down with drop box the files don't have the necessary permissions. Here's the bugger, I can't batch update the files by modifying permissions on a folder, I'm having to do it right to the file level and even worse, one at a time! I can't have this.
I'm relatively new to 2008 r2 and IIS 7 so I have no idea what's happening here. Can someone explain what is going on and if there's an IIS/file permission setting I can update to resolve it at the top level folder?
I've tried adding anonymous permssions on the website in IIS and I've added permissions on the folder for IIS_User (even Everyone). I have an Administrator account and that's already set to allow me to read/write/modify the files.
This is typically the message I'm getting 'An error occurred loading a configuration file: Access to the path X is denied'.
This is happening on ascx & aspx files as well as config files.
Edits:
The site is visible when debugging from Visual Studio.
The site is operating in Full Trust (internal)
Please help, this is stopping me from working and driving me insane!
By default in IIS 7, websites run as the local system's network account (NetworkService), not as IIS_User.
To verify, in IIS Manager, select the Site in question, click Basic Settings... and check the Application Pool it is assigned to. Then go into Application Pools and check the Identity for that Application Pool. Make sure that user listed is in the ACL.
Adding Everyone to the ACL should work instead, but just in case I would suggest you check the above. Also of course make sure when you set the ACL to check the box for resetting inheritance on all subfolders, if that is appropriate for your application.
You could also try setting the identity of the application pool to a local (or domain) user you have created which has access to your application directory.
Hope that helps.
Regarding whether other identities would work for your app pool, that depends entirely on whether those identities have permissions to all the files and/or databases and other resources you application needs to access. Right now you have the application running under your user account, which is generally not recommended. IIS has your password cached, and if you change it, your application will stop working until you update the application pool configuration.
As far as setting NTFS permissions, it can get tricky. Once you have disabled permissions inheritance, that file or folder will need to be updated individually every time you need a permission change. The flip side of this is that you cannot remove inherited entries on an ACL, you can only add to them. However you can design a strategy that offers a baseline level of permission at the root of a file structure, and then add permissions to subfolders/files.
In order to check & reset inheritance on a folder, go into its properties, security tab, click advanced, then click Edit. You can see whether this folder inherits permissions from its parent, and optionally wipe out all subfolder/file permissions and enable inheritance on all child folders & files.
Hope this helps.
