I get the following .NET error when trying to load my Orchard CMS website:
Access to the path '\\.........\www\App_Data\Dependencies\Lucene.dll' is denied.
Exception Details: System.UnauthorizedAccessException: Access to the path '\\WDP\DFS\30\7\4\5\3024678547\user\sites\5481517.site\www\App_Data\Dependencies\Lucene.dll' 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 <identity impersonate="true"/>, 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.
How do I actually go about granting access rights? I've googled and found I should go into the server and right-click on the directory and edit the properties. BUT, I am in a shared hosting plan and don't think I can do that.
Am I pretty much at a dead end?
Things I've tried:
Setting file permissions through FTP, but I get a:
500 'SITE CHMOD 777...command not understood
I've downloaded and installed IIS Manager and successfully connected to my site, but still did not find any options to set permissions in there.
I've also called Network Solutions, but all I was told was to try to do the file permissions settings (as I mentioned above).
Thanks in advance.

I've a requirement of writing into a network folder from ASP.NET.
So I just used Streamwriter class and it works fine when trying from local system using Visual studio web server. But when trying to host it into IIS on the same machine writing into network folder not working at all.
It saying
Access to {\MYSERVER\specialfolder} is denied
So I thought it as some access issue. What I tried was as follows
Changed Default Applicaiton Pool (Which is the pool using for my
domain) identity to local system (And tried the other 4 ones too) :
Still the error
Authentication change for my site. Change from
Anonymous for specific user IUSR into Application pool Identity : No
help
Right clicked on my site and then selected edit permission, then
specified write permission for IIS_IUSRS group : Not worked
Also I tried, Right Click on the network folder itself -> security ->
But there is not IIS_IUSRS group
What else I'm missing for having the write permission into network
folder.
Details about my system
IIS 8.5
WINDOWS SERVER 2012R2
VISUAL STUDIO 2015
As far as I know, the IIS use the LOCAL user which generated by the IIS, this is local computer account.
If you want to access another network folder, you should set the enough permission to the IIS application pool identity.
You should use AD to assain enough permission to a spcial AD account.
Alternatively, using ActiveDirectory you could create a Domain User account, configure the application pool identity to use that domain user, and grant that user access to the network files.
More details, you could refer to below article:
http://www.iis.net/learn/manage/configuring-security/application-pool-identities
I am using IIS7 to host an asp.net 2.0 site. However, whenever I browse it I get the error
The requested page cannot be accessed because the related configuration data for the page is invalid.
Now I realize that this is because the IIS_IUSRS does not have access to the web.config. My question is how can I grant access to IIS_IUSRS
When I look under Application Pools and check the Identity. It shows
ApplicationPoolIdentity(default), LocalService, LocalUser and Network Service
However, I cannot seem to find IIS_IUSRS
Where do I find it
IIS_IUSRS is actually a Windows group so you won't find it under the application pools in IIS.
If you need to grant this group access, then this will need to be done via the file system, e.g. you could go to the folder where you have deployed your ASP.NET application and grant permissions to the group:
I published my website on the IIS6.

How can this be handled?
You need to give writing permissions to the Aspnet user in that folder.
See this:
http://devnet.logixml.com/rdPage.aspx?rdReport=Article&dnDocID=209
Best regards.
It's not a good idea to write to a variable directory under C: drive. I suggest you not to give permissions to write under C, rather, write to a directory under your web app's directory, which you can get by Server.MapPath("~"). Make sure you give write access to the application pool's user account to whatever folder under your app directory, and you'll be much safer.
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.

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.
I have a problem when I try to access a file from a shared folder in a local network.
When I run the application in Visual Studio it works fine and I can download the file, but when I deploy the application to IIS, it simply doesn´t work.
I don´t understand why, cause I give full permissions to all users, including NETWORK SERVICE and IIS_USR.
I'm currently using my computer to test this. It has Windows 7 and running IIS 7.5. The shared folder I'm trying to access is on a Windows Vista installation which doesn´t have IIS installed.
The code to download file is this:
protected void button_Click(object sender, EventArgs e)
{
Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=S10.png");
Response.WriteFile(#"\\192.168.1.82\Machine\file.png");
Response.End();
}
and it gives me the following error:
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more
information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Acesso negado
ao caminho '\192.168.1.82\Machine\file.png'.

You have given access rights on the file system (full control is overkill for this, read or modify should be fine), but you will likely find the share permissions are still at the default of read only. You need to change the share permissions.
Read this for more info.
EDIT: The reason it works ok when debugging is because it's using the account you are logged on with, not the aspnet account in VS.
Create a new app pool, running under a service account which is a member of the IIS_WPG group on the IIS server and has permissions on the share you want to write back to (remember to set the service account to password never expire). Give the IIS_WPG group Read & Execute, List Folder Contents, and Read permissions to the Web site directories. Change the web app to run in this new web pool.
solution 1:
You can define a domain user. Let IIS server run with this user ( through Pool identity or 'connect as'). give this user access rights on Shared folder.
Solution 2:
Add IIS server account into user group of the server that contain shared folder, Give this user access right on shared folder.
If the file and the Machine folder is in C Drive, then you also need to give permissions to the root folder containing this file path because C Drive is usually read/write protected as it has System Files in it.
So for example if the file is in the path C:\Machine\file.png.
Then you need to add and give relevant permissions to IIS users group to Machine Folder and not just to the file i.e., file.png.
