I have an asp.net webapplication that uploads files from specific folder on the server. locally everything works fine, but when I deploy the application to the Webserver, I begin getting the error:
"Access to the path "Access to the path
'\192.168.16.5\Files$\2\tmp\MV12148B-801_DWG1.CGM' is denied." is
denied".
Shares with a "$" suffix are administrative shares and only those with administrative permissions are able to use them. More-than-likely the account under which your IIS website is running (specifically, the account under which your website's Application Pool is running) does not have administrative rights--nor should it.
I suggest giving it a "regular" share name and then you can better control the permissions associated with that share.
Give the identity--under which your Application Pool is running--write permissions to the new (regular) share that you set up.
If the Identity for your App Pool is "ApplicationPoolIdentity", then the account name to use is:
IIS AppPool\{application_pool_name}
Therefore, if your App Pool name is DefaultAppPool, then this user account name is:
IIS AppPool\DefaultAppPool

I am trying to store images in a FileTable that is accessible from a website.
According to my understanding, the FileTable needs "SELECT" granted to the account running ApplicationPool that the website runs in.
Example of what I have:
IIS (6.2)
Application pool user : Domain\Bob.
SQL Server login Domain\Bob
Database has Domain\Bob in db_owner group. I explicitly granted Domain\Bob select on the file table also.
DB.dbo.FileStream_FileTable is \\DEV\FileStream_FileTable\
IIS has SiteA
SiteA has virtual directory Image targeting \\127.0.0.1\DEV\FileStream_FileTable\
If I look at the IIS authentication, IIS errors saying insufficient permission to access web.config - but there is no web.config.
On the server, running Internet Explorer, referencing an image as \\127.0.0.1\DEV\FileStream_FileTable\<...>\Image1.jpg it resolves to the jpg.
On the server, running Internet Explorer, referencing an image as HTTP://127.0.0.1/SiteA/Image/Image1.jpg, IE errors (same error as the authentication error)...
Config Error
Cannot read configuration file due to insufficient permissions
Config File
\?\UNC\127.0.0.1\dev\ItemImage\web.config
There IS no config file.
I have tried specifying the Windows user (Domain\Bob) context when accessing the virtual folder "Images" targetting \127.0.0.1\DEV\Filestream_FileTable
and also not specifying the windows credential...
I do not understand why the Image is visible using the UNC path in Internet Explorer (it must authenticate my context as having select on the filestream_filetable table) but not when using the context specifying a Windows context of a user who also has select on the table, in IIS.
NOTE: As an experiment, I modified the user, in IIS, used to access the share to Administrator. Then the IIS site resolved the image.
(Virtual directory targetting the \\servername\sql_instance_filestream_handle\directory\tablename)
The Windows User Domain\Bob has full rights on database - database owner.
There is another user's question, Access to SQL Server FileTable from IIS, that has servername in file share being a potential issue if the IIS and SQL server is on the same host, which I have taken into consideration.
I have added Domain\Bob to IIS_ISURS group...
What is Domain\Bob not a member of that grants access?
I can't very well make all my IIS shares accessing with Administrator accounts!
In some case, IIS will try to create web.config if the UNC path just return access denied error. If IIS failed to create web.config, It will also fail to access web.config with 500.19.
So please ensure your Application pool identity is set to a domain account who have read/write permission to access the folder.
Then please try to set Anonymous authentication->edit..->Application pool identity.
The Windows user Domain\Bob was not a login in the DEV sql instance.
Creating a sql login solved it. blush
Database level had the user, yes, but the SQL server didn't have a login.
facepalm
My deployed application is creating file on a shared location.
To get it work and allow applicaiton to write file on shared location, I have set applicaiton pool as domain\user account.
Please guide me how should i get it working using applicationpoolidentity account too ?
Versions of IIS 7.5 and later create a virtual app pool user account running under the umbrella of ApplicationPoolIdentity. This will be unique to that app pool and therefore won't be the same account as on another server.
You'll need to have the same specific local user account or domain user account set as having permissions against both the shared folder and the app pool.
In my asp.net web application I am trying to retrieve images from a shared network folder. When I put this website live in IIS, I am getting an error that "Access to the path is denied" when I try to access the network folder. What is considered the user that IIS uses, and how would I grant permissions to the network folder?
Thank you.
The issue is because your application pool identity or the user that IIS is using to run the worker process does not have permissions on the network path.
You may want to grant this user permission on the network path. However, if you are using IIS AppPoolIdentity that is not possible as they are built-in account per machine. As is the same with any buit-in account.
I would advice you to use a network account and give that account appropriate permissions on both IIS and the network share.
You may have to add this user to the IUSR group.
I am trying to have my local website within dropbox using IIS. When I add the dropbox directory I get the error: The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that \$ has Read access to the physical path.
I am admin and have allowed all access to the dropbox folder. What is wrong?
You should add IIS user account to the list of users who are allowed to view/read the files. IIS usually runs via separate user account for security reasons.
This is done the following way:
Right-click on your site folder in Dropbox
Select "Security"
Click "Add"
Find IUSR user and/or IIS_IUSRS group
Add them both (or one, if only one is present) and assign them read permissions
Try adding your site folder again.
This should fix the issue.
Ok I'm stumped. I've configured an IIS 6 website with its own App Pool, which has its own AD domain credential. When I attempt to browse the site, I see a page that simply says "Access is denied.". There is no error code or information in Event Logs.
I am able to open Notepad with the app pool account credentials (and open the html file I'm trying to browse).
If I add the app pool's domain account to the local administrators group, the site loads. However, this is not acceptable for our environment.
I have successfully configured this site on two servers (that are supposed to be identical in a load-balanced pair). However, try as I might, I can't find any difference between these two servers' configurations.
Is your pool identity present in the local group IIS_WPG ?
This group ensure the Worker Process will have the required privileges to run correctly.
Also, your WebSite root folder must have Read permissions for IIS_WPG, which is the case if your root is in Inetpub\wwwroot.
Same for C:\WINDOWS\Microsoft.NET\Framework\vx.x.x.x\Temporary ASP.NET Files + Write, if you run ASP.NET WebSites.
FYI, in IIS 7, the group is now known as IIS_IUSRS.
Default permissions and user rights for IIS 6.0
Configuring Application Pool Identity in IIS 6.0
I reinstalled IIS 6 and the error has gone away. After reinstalling IIS, I had to reinstall .NET 4 as well.
Thank you very much for your suggestions and advice though!
