Security - Accessing Network Folder With Network Service Account
Aug 17, 2010
My ASP.NET MVC 2 application runs under built-in local NETWORK SERVICE account. I want to set up access permissions for the folder which resides in another computer, but in the same domain. I located that folder right-clicked to open its properties form, clicked to Security tab and pressed Add button which displayed Add user form with correct domain name in the location field. I referred to the account with following syntax:
<domain name><server name>$
because I learned that NETWORK SERVICE account uses machine account when connected to other computers in the domain. However, the system couldn't find the account, so refuses to add the account. Without the domain name it adds a user, but that user seems to be local user, not web server's NETWORK SERVICE account. What am I doing wrong?
By the way, the above syntax worked when I created login for the sql server which is different computer from the web server.

How to add the ASPNET/NETWORK SERVICE account with Write permission.

First, I felt I had a clear understanding of how the Network Service account work. It is the default account ASP.Net runs under and has very limited access. I have verified in the Application Pool that ASP.Net is running under the Network Service Account. I have a UNC file share that is located on another server, let us say "\myservermyfiles". I have logged on to "MyServer" and right-clicked on the shared folder "myfiles" and just for the sake of testing, went to the Shared Tab->Permissions and added the Network Service account and gave it "change and read" access. I then went to the Security Tab, added the Network Service account and gave it all permissions. For some reason, I am still getting an "access denied" exception. I know impersonation is an option at some point, but I would really like to know why my ASP.Net application cannot copy a file to this share just for my own personal understanding given the fact that I gave the Network Service account the proper access. Like always, I will continue to research.

I've been researching and I've spent pratically all day on this. Here's my issue. The website uses forms authentication that we authenticate against active directory. I've been attempting to access files we have on a network share and push them down to the user (when they request them) in an http response. I keep getting "Access to the path <unc path> is denied".
Here's the code:
[Code]....
Things I've tried:1) When I add the "Computer" to the permissions of the folder it works and I dont even need to emulate a user (essentially just commenting out this code), but I'm not sure we want to explicitly give the computer access to some of our network shares 2) I've verified it's the correct username and password for the active directory account and that they have permissions on these network shares 3) I've fooled around with the WebProxy class with no luck (as I'm not entirely familiar with it) 4) I've tried impersonating the user by creating a windows token and passing the token as credentials (i've done this with similar websites) with no luck, plus this seemed a bit complicated for something I figured would be relatively easy.Its almost as if, the WebClient class isn't even using the credentials i've passed it.We've got it working now, but only by giving the "Computer" specific permissions on the network shares, which we'd like to avoid.

We have an issue with an internal application, where accessing it from LAN (private n/w) works fine, while access from external n/w throws up erratic behavior.
The Current System :
an aspx page (asp version 1.0) hosted on the IIS server (6.1). The front end is a vb form that connects to a sql 2000 database.
Users' credentials authorized using NTLM security.
Access from an external n/w - a reverse proxy configured with an ISA server 2006 to authenticate credentials.
Domain Controller - Windows Server 2008 R2 x64
The issue when accessed from external n/w :
everytime an entry from a drop-down is selected from an Ajax enabled control, instead of the fields populating, the page gets refreshed and the content of the box are cleared.
Also, clicking on other items that normally hyperlink to other pages, results in nothing happening.
Upon investigation, we realized that :
Everytime it fails, a string - "&AuthResend" followed by an alpha numeric string is attached, which attempts to authenticate the user's credentials everytime a request is made to the server.
ISA error logs yielded the following error msg :
"12210 Internet Server API ( ISAPI ) has finished handling the request. Contact your system administrator. "
This behavior is inconsistent except when accessed from Google Chrome, where it fails each time.
We have applied all the recommended hot fixes from Microsoft's KB pages.

A month ago I got everything working but now my code has changed and my server may have been misconfigured.
Basically, I'm running IIS 6.0 and Win2k 2003. The webserver will map a network path UNC share at: //wave/test
Also, I have webconfig set up to do: impersonate = true (no username/password defined)
the path //wave/test is another computer that runs Windows XP. Wave is the computer name, test is the folder name. So C: est is the folder to access. The current permissions under C: est on the file server is: Administrator, IUSR_WEB (read-only) and "Wave_user" (read-only)
Back in WinServer 2003, i've added a virtual directory and mapped to \wave est and applied a local username/password for Wave_user. I am able to see/browse all the files in IIS 6.0 and see the files/folders. I call the virtual directory alias: "Waves". Inside Authentication method for this virtual directory, i applied Wave_user and the local password of the local file-server PC , and checked enable anonymous access w/ integrated windows authentication.
Also, back in virtual directory, I set "Connect As" to wave est as username and password as the local password.
When I access the webapplication, using my current local PC credential, and try to access the network share, which in C# is the command: server.mappath@("wave"... i get a Server Error 401. in the browser.

I wrote a web service sometime back, and uploaded to one of our network Server's IIS. The webservice needs to access a network folder, which was working perfectly fine till a month ago. Now, when we use the webservice in our .Net application, it fails with the exception message "Access to the path '\<networkMachine ><Folder >' was denied" (may be some group policies changed). But when I run the webservice from my local machine's Visual Studio debugger, it can access that folder. What could be different on the server's IIS w.r.t. my service? Why was it able to access the network folder before but not now? Please note that I can manually access that shared network folder from my machine, and also when I remote desktop to that <networkMachine> from windows explorer.
I saw in the task manager on the server that the IIS process w3wp.exe is running under 'NETWORK SERVICE' account. Though the network folder is not shared specifically with this account, but that has given read & execute access to 'Everyone'. Then what is the problem that it cannot access the folder. By accessing I mean creating a 'DirectoryInfo' object of the path '\<networkMachine ><Folder >' and reading all the subfolders -
just read.

I have a web application that uses Windows Authentication, not forms, and has identity impersonate = true.
From an .aspx page, the following code can create a folder on a network share successfully but fails in my .asmx page.
dirPolicyFolder.CreateDirectory(ConfigurationManager.AppSettings("PolicyApplicationsPath") & strFolderName
I have confirmed that the same user is logged in both examples, permissions on the parent folder are set correctly, and the logged user has propper right to do this.
If I change the path to a local one, the asmx page can create the folder.Why would this fail when running in the .asmx page?

I am stumped. i want my asp.net website to access a network share folder which is located at say, //hero/superman. I can do it manually.
I've done the following:
1. Included <identity impersonate="true" userName="IUSR_TEST" password="test" /> in my web.config.
2. Set anonymous access in IIS 5.1 with username IUSR_TEST and password: test in the account that is used for anonymous access. Checked integrated windows authentication.
3. Created a profile for IUSR_TEST in computer/management/local users and created the password: test for it. It is a member of guest.
4. Created a user account IUSR_TEST for the network share computer. gave it the same username and password.
4. On the network share computer, I've enabled access for the following people: ASPNET, NETWORK SERVICE, and IUSR_TEST.. all with full potential (for now) for the directory path in question //hero/superman which is really located on: c:herosuperman. I've given it full access.
But when I StreamReader fs = File.OpenText(Server.MapPath(@"\herosuperman est.txt"); I get the error "UnauthorizedAccess Exception". Access to the path \herosuperman est.txt is denied.
So what did I miss, what am I doing wrong. The key thing here are:
the webserver is on a domain. the network share computer is NOT on a domain, it is on it's own workgroup. This workgroup, lets just say is called "villains". So if I have to manually map the network drive to access the files, I must type: /villains/IUSR_Test and password: test to be able to map it on my webserver local computer.

I have an Image control with the ImageUrl property set to point to an image on a network folder, the address looks like this:
\fs01PRODUCTSimagesAM101.jpg
It renders correctly in IE but not in Firefox.
pasting the url/path directly into the browser, the address is maintained in IE: \fs01PRODUCTSimagesAM101.jpg
But in Firefox, it is converted to this: file://///fs01/PRODUCTS/images/AM101.jpg
I suspect this is related to the problem.

i developed a simple web application. A label and a button. On click of Button, the label will display Hello World.
When I deploy this web application on my web server and access the URL, I get this error message.
The current identity (NT Authority/Network Service) does not have write access to C:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
I have tried the following -
Navigate to C:WindowsMicrosoft.NETFrameworkv2.0.50727 and typed the following command -
aspnet_regiis -ga "NT AuthorityNetwork Service"
After that also, it did not work.
We checked the permissions of the folder Temporary ASP.NET Files and for the Network Service user, we checked the Security Permissions and it has all the permissions as required.

We have ported an existing ASP app to ASP.NET and are now having problems printing from the server to network printers, e.g. to\hereprintername.
This used to work with our ASP app, and printing to server-locally installed printers still works.
I suspect that there is some security or Group Policy object that must be changed to allow printing from an ASP.NET web application to a network printer?
Or perhaps, accessing Active Directory from an ASP.NET application is a problem?

I have a few computers (with Vista Business OS) connected in a private network. A C#.NET application running on one computer is currently able to access the network shared folders without problems. However, I am trying to get an ASP.NET application on that computer to access the same folders but I am getting "Access denied" errors. I added NETWORK SERVICE to all the shared folders' security (with full control) but it still gives the same errors.

In the IIS, it shows that the web app (i'm using) is using an application pool that uses NETWORK SERVICE account for identity. But when I debug/run my web app, User.Identity.Name shows that my windows user login instead. I checked my web.config file, and it does not have Impersonate enabled. In fact, I set it to false, and it still shows the same.

I want to upload files to the web servers from the client machines.
Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
