Access to the path 'Global\{xxx}_YYY-YYY:13552' is denied. Hangfire?

As the title says I encounter a "Access to the path" error in my MVC web application. The sites application pool is DefaultAppPool with identity Network Service. I have set Full Control to the Network Service user with no luck, I then tried to give Everyone full control but it still does not work. I'm running another application from the same folder (C:\Users\YYY\Documents\Visual Studio 2015\Projects) and it works without a problem.
The file that fails contains the method that starts Hangfire. Could this have something to do with it?
I'm running Windows 10 Pro with IIS 10.0.
public void Start()
{
lock (_lockObject)
{
if (_started) return;
_started = true;
HostingEnvironment.RegisterObject(this);
GlobalConfiguration.Configuration
.UseSqlServerStorage("connection string");
// Specify other options here
_backgroundJobServer = new BackgroundJobServer();
}
}

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 File
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.

Found the problem, I had two websites with Hangfire running on the same application pool. When I created a new application pool for each website everything started working.
It seems as both instances of Hangfire when running on the same application pool tried to communicate through the same port and because of this the application that got started first was the only one to be working. The reason they were on the same application pool to start with was pure laziness, I only created a virtual directory from within Visual Studio at my local IIS to run the project.

IIS - Access to the path is denied

This question have been asked like million times, but I have tried those solutions and still can't find out why this error is coming up:
Access to the path '\server1\Folder1\Folder2\Folder3\file1.dwg' is denied.
Here is the action which returns the error:
public ActionResult Download(string fileName)
{
fileName = fileName + ".dwg";
string path = Path.Combine(#"\\server1\Folder1\Folder2\Folder3\", fileName);
return File(path, "application/octet-stream", fileName);
}
I have tried to giving permissions to "Folder3" for multiple usernames, for example "SERVER1\NETWORK SERVICE" - Full Control.
Application is running under Default Web Site. Application is running under DefaultAppPool and DefaultAppPool has identity of "NetworkService".
Following code gives identity "NETWORK SERVICE".
WindowsIdentity identity = HttpContext.Request.LogonUserIdentity;
The application was working fine (same download directory) on my own computer, but after deploying this problem showed up.
Server is running Windows 2008 R2 SP1 and IIS 7.5.

Try this:
"Access to the path 'xxxxxx' is denied."
As error says you need to assign permissions to folders
Right Click Folder
Go to Security Tab
Click on Edit
Click on Add
Click on Advanced
Find Now
Give Permission to IIS_IUSRS (Full Control)
Click On OK
Click On OK
Click On Full Control in allow
Click On OK
Again Run the Application
Note: if these steps are not working, then try to give same permission to NETWORK, NETWORK SERVICE users

For my case, I went to the root folder of my project, right clicked on it and opened the properties window and unchecked the Read-only attribute. After clicking OK, all started working.

If anonymous authentication is enabled on your server set read permissions for the IUSR account. To allow access for the application pool identities set read permissions for IIS_USERS group. For UNC-path sure that there are relevant permission for your shared folder (see https://technet.microsoft.com/en-us/library/cc726004(v=ws.11).aspx for details).

Please give the full control permission to your directory. Please do this
-Right click on folder
-Go to security
-From Edit give access to IIS_USERS

file copy to remote server access error

I kept getting Access error on the following code:
var fileName = "test.dgi";
var local = Path.Combine(#"C:\aaa", fileName);
var remote = Path.Combine(#"\\sw933chipqw001\tmp\", fileName);
Error I got is:
Access to the path '\sw933chipqw001\tmp\test.dgi' is denied.
I tried to give Read/Write access to IUSR, IIS_ISURS and the service account I set in the app pool. nothing worked. I'm using IIS7.
But if I add "Everyone" with the Read/Write access, it works. Anyone know what is the specific account that I need to give permission to?

Well the default account that an app pool is running in IIS7 is:
IIS AppPool\<AppPoolName>
In your case it's probably
IIS AppPool\DefaultAppPool
Here is a little bit more info.

I just tried to grant "Authenticated Users" full control on the remote folder and it works!

How can I take ownership of files with incorrect security?

I have a folder structure on a (Server 2003 SP2) file server and I need to delete it using C#. I can't do that because I get System.UnauthorizedAccessException: Access to the path '\\xyz\blah\...' is denied. (where the path points to a sub-folder) because the permissions on the sub-folder are incorrect. So, I've been trying to take ownership of the files and this fails with System.UnauthorizedAccessException: and now I'm stuck.
Detail
I have an admin tool used by users with minimal privs. They need to delete folders and files to which they don't have access, so I wrote a UI which calls a web service. The web service runs under an AppPool with a domain account which is (now) a member of Administrators on the file server, so it should have access to delete the files and folders. But some of the folders have incorrect permissions. For example, when I log onto the file server with an account in Administrators and open the security tab for the folder, I see:
And for these folders my code doesn't work.
I've given the appPool account 'Take ownership of files or other objects' on the web server using Local Security Policy. Other posts (e.g. this one) have pointed out that you need to explicitly enable SeTakeOwnershipPrivilege in code and recommended Process Privileges which I'm using in my web service:
using (new PrivilegeEnabler(process, Privilege.TakeOwnership))
{
System.Diagnostics.Debug.WriteLine(String.Format(
"Privilege:TakeOwnership status: {0}.",
process.GetPrivilegeState(Privilege.TakeOwnership)));
SetFolderOwnerToCurrentUser(folderName, groupName);
}
When I run this, I see:
Privilege:TakeOwnership status: Enabled.
(Before adding the priv via LSP, I was seeing Privilege:TakeOwnership status: Removed.)
In SetFolderOwnerToCurrentUser if I just use
var directorySecurity = new System.Security.AccessControl.DirectorySecurity();
directorySecurity.SetOwner(WindowsIdentity.GetCurrent().User);
System.IO.Directory.SetAccessControl(folderPath, directorySecurity);
I also get System.UnauthorizedAccessException: Access to the path '\\fs\blah' is denied. Again, it's the sub-folder it's complaining about.

file upload C# asp.net

i am trying to upload files in asp.net and putting a specific path to be saved. windows user.
it is outputting me an error :
System.UnauthorizedAccessException was unhandled by user code
Message=Access to the path 'C:\Users\USER\Desktop\fyp2\CMS TEST4\CMS\CMS\Upload' is denied.
my code is:
var guid = Guid.NewGuid();
if (File.HasFile)
{
var length = File.PostedFile.FileName.ToString().Length;
var ind = File.PostedFile.FileName.ToString().IndexOf('.');
var sdfs=guid.ToString()+File.PostedFile.FileName.ToString().Substring(ind, length - ind);
File.PostedFile.SaveAs("C:\\Users\\USER\\Desktop\\fyp2\\CMS TEST4\\CMS\\CMS\\Upload");
}

The ASP.NET worker process does not have access rights to that path. By default I believe IIS worker processes run under the Network service account. You can either add write rights for the folder to this account, or set up a new Application Pool with a different identity (i.e. a user that does have write rights).

As simple as the error puts it, your application requires the folder to have proper write permissions.
I'm asuming this is a Web Application. In that case, you'll need that the user which IIS uses to run applications has Write permissions over the specified folder.

The users directory is fairly locked down. If the account the web server is running under is not the specified user, it will not, by default, have access to the path. You can either grant explicit access to that path to the account running your web server, or create a folder with appropriate permissions external to that path and create a link on the user's desktop.

Looks like current user has not permission to save. Before writing try use FileSystemRights with AccessControlType.Allow to know permission info of the destination.
