Folder Access denied error when trying to create a file from a web project - asp.net

I have solution in which there are two projects one is a web project and one is a windows application. The windows application does some file read write things. Recently I have got a requirement to refer those in Web project. I referred the windows project in my web project and it worked great.
But the issue is there is a file writing part in Windows Project which is triggering an Access Denied error. When I am running locally its not triggering that file error. When running from IIS that error triggers.

You need to assign Write access to IIS_IUSRS user group in that folder. Just right click on the folder, go to security tab and add IIS_IUSRS with read + write access and click OK.

Access denied when trying to delete a file in Temporary ASP.NET Files folder

I am unable to run a web application after a build in VS 2013. I get the following error:
Access to the path 'C:\Users\Thelonius\AppData\Local\Temp\Temporary
ASP.NET Files\vs\3874c594\43dbfd8b\DotNetOpenAuth.OpenId.dll' is
denied.
I tried to delete the DLL using Windows Explorer directly, but I was met with the following dialog:
You require permission from the computer's administrator to make
changes to this file DotNetOpenAuth.OpenId.dll
I found it odd since I was running as the administrator. When I tried to change the permissions from the Security Tab in Explorer, I got the following message:
You must have Read permissions to view the properties of this object.
I am unable to change the ownership on the project. Is there a solution to this problem or should I just make another ASP.NET temporary file folder? This is strange. If it helps, I am running Windows 10.
For what it's worth, Windows Handle utility claims that VS 2013 has the file open, but why can't it delete it? Also, if the file is open by Visual Studio 2012, shouldn't the error message say that the file is open?
To been able to clear the Temporary asp.net directory you need to :
Stop the IIS service (or just stop the web site that you wish to clear)
Close all visual studio programs (or only the web site that you work with)

using Process.Start in an IIS Website

I have created an ASP.NET website using VB.NET. The functionality of the website generates a .bat file and saves it in a location - it then uses Process.Start(filelocation) to run the bat file.
This works fine when in debug mode on my PC - but when I have uploaded the website on to an IIS 7 server, it creates the file (proving that it has access to the area), but seemingly cannot run it?
I am assuming there is a permission issue here - Any ideas what I am missing?
Thanks

Every webapp in IIS run under a specific user. Check if that user has privileges to run applications, in particular the *.bat (in your output directory) and related *.exe files.
If you do not use impersonation, you can set the user at App pool level.
My suggestion is to create a dedicated Windows user with the right permissions and run the app pool under that user. The app pool should contains only your web application.

I don't seem to have an ASPNET user account running on my machine

Hi: I'm reading up on ASP.NET, and just came to a chapter that explains how to upload a file to your website. It says that in order to save a file to your file system, in the case of every OS except Win Server '03, an ASP.NET page executes in the security context of the ASPNET account. I don't have an ASPNET account running on my machine (win xp pro sp3; .NET 3.5). The program runs fine, by the way, I'm just trying to understand what an ASPNET account is exactly, and why it doesn't seem to show up on my list of user accounts. Thanks.
ASPNET is only used if use IIS. This was the norm in ASP.Net 1.1
However in new versions of Visual Studio IIS is not needed, so it uses an internal web server.
If ASPNET exists in a command window ( Start -> Run cmd Clikc OK) type and press enter
net user ASPNET
you should see the details of the account and in Task Manager you will see a process asp_wp.exe
File Access
The Network Service account has Read and Execute permissions on the IIS server root folder by default. The IIS server root folder is named Wwwroot. This means that an ASP.NET application deployed inside the root folder already has Read and Execute permissions to its application folders. However, if your ASP.NET application needs to use files or folders in other locations, you must specifically enable access.

How to give Write Permission In IIS Version5.1?

I have developed an web application using Asp.net ( .Net Framework 3.0). In this application I have created a folder in the application directory. This folder contains an xml file to read and write data. when I tested this application in my local machine I can read and write data. But, when I deployed in IIS Ver5.1, I can read the data but when I try to write data in xMl file i could not.
So, I hope this problem is in IIS. I gave the write permission to my application folder in IIS.
or Is there any steps to do that?

ASPNET user does not have write access to Temporary ASP.NET Files

I get the following error when running my Visual Studio 2008 ASP.NET project (start without Debugging) on my XP Professional box:
System.Web.HttpException: The current identity (machinename\ASPNET) does not have write access to 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files'.
How can I resolve this?
Have you tried, the aspnet_regiis exe in the framework folder?
I had the same problem. This is what I did:
Go to c:\windows\microsoft.net\framework\v2.0.50727
right click on "Temporary ASP.NET files"
Security tab
Select "Users(xxxxxx\Users) from Group
check "Write"
OK
Either grant that user the level of access to that directory, or change the identity that the application's application pool runs under - in IIS Manager, determine what App Pool is used to run your application, then in the App Pool section of IIS Manager, look at the properties for that pool - the tab you want is "Identity" I think (this is off the top of my head).
You can set it to another user account - for example, Crystal Reports .Net requires update and delete access to C:\Temp - so we have a "webmaster" user, with administrator access, and use that identity for those applications.
You can try to fix it using the automated regiis utility aspnet_regiis.ext available in c:\windows\microsoft.net\framework\v2.0.50727
Otherwise just manually add the needed file permissions as noted in the error.
you can right click the Visual Studio & select run as administrator.
I had this problem when trying to build a Web Deployment Project (*.wdploy).
Simply creating the folder on the framework path solved the error.
Just because the most recent answer is 5 years old, what had to be done in our environment was to delete the app, app pool and recreate them.
We evidently have some security under the hood with recent changes to it.
Doing this re-created a folder in Temporary ASP Net Files with all the correct permissions. Why the one site I happened to just get from source control, rebuild, etc. failed this way, no idea. 2 others recently set up where Get Latest Version was downloaded, rebuilt, etc. they just worked.
But ripping out the app, app pool and just recreating them with the same IIS permissions as the 2 other known working sites recreated all the needed objects and now it all works.
Make sure the ASPNET user has permission to write to that folder. Right click on the folder, Properties, Security tab.
