Security :: Webservice Is Denied Access To Network Folder
May 27, 2010
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.

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.

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'm not able to open the file when I click on the link on page in MVC. I get the following message. I've added the impersonation in the code. I'm able to delete and save the file.
Access to the path '\servernamefolder1folder2folder3foder4filename.pdf' is denied. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access to the path '......same as above....' 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) 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 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.

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 am using the following in my webconfig, so that only admin an access the admin folder.
<location path="Admin" allowOverride="true">
<system.web>
<authorization>
<allow roles="Administrators" />
<deny users="*" />
</authorization>
</system.web>
Now when the guest user tries to access this he is redirected to the Login page. I want the user to either sho a popup that user cannot access it or just stay on the same page with some error message in a label on that page... Here is more code in webconfig
<authentication mode="Forms">
<forms loginUrl="Login.aspx" protection="All" name="Cookie" timeout="120" path="/" slidingExpiration="true"
defaultUrl="Default.aspx">
</forms>

I'm working on an ASP.NET application that accesses Team Foundation Server 2010 and creates new work items. The application is running in the DefaultAppPool, using NetworkService as the identity. I'm getting the error below:
[UnauthorizedAccessException: Access to the path 'Cachev10' is denied.]
[code]....
We were able to work around the issue by turning the Cache folder into a network share and giving NetworkService full access to the share. I'd prefer not to have to do this, but it seems to be working correctly now.

I have implemented role based security in my asp.net 2.0 vb.net application using windows authentication and the windowstokenroleprovider and limiting access to certain pages using the location tag to specific active directory groups.
The issue is that when a user tries to access a page they are not authorized to view it brings up a login prompt and when it does not pass it takes them to the default page that tells them they are not authorized to view the page. I am wondering if there is a way to throw up a custom page that tells them they are not athorized to view the page that I can incorporate into the site itself with the header and so forth? if this page could come up in lieu of the sign in box popping up as well.

I have the following web.config file in my MemberPages directory:
<configuration>
<system.web>
<authorization>
<allow roles="member" />
<deny users="*" />
</authorization>
</system.web>
</configuration>
If the User is a "member", he/she is allowed access to web pages in the MemberPages directory. Otherwise, he/she is denied access. The mechanism works. However, when the User is denied access, the following very unfriendly message appears:
Server Error in '/MyWebSite' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies)could have been removed, had its name changed, or is temporarily unavailable. the following URL and make sure that it is spelled correctly.
Requested URL: /MyWebSite/MemberPages/member_page.aspx
How can I redirect the User to a more friendly page if he/she is denied access?

I am new to IIS and have some questions.
I've put my application on IIS with a App Pool I newly created. The App pool setting is integrated and networkservice.
My application reads a local file from a local machine. When it tries to do that, I receive an exception saying that "Access to the path c:..xxx is denied". Isn't the app using the credentials logged into the local machine?!
doesn't "integrated and networkservices" mean.. use the credentials logged in to windows?

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.

I'm a lowly DBA.I am supporting a web app that allows users to upload images (among other documents). The system is deployed and working and not having issues with the uploads. However, I upgraded my development box recently and since then I have been encountering an "access denied" issue. Initially I thought it was a simple security issue but now it seems it is more complex.

I have set up a simple bit of code to upload an image to the web server. It works offline without a hitch but online I get an error saying denied access.I am not overly surprised to be honest as I have not configured anything on the server (through my web host "Mochahost") to allow unknown users to upload files. I wonder if someone could point me in the right direction.

I have read this post [URL] about something similar to my problem, but here is the thing, this Web Application worked without problems until someone changed some rights in the folder: '\ServerNameFolder' I have write permissions for both "DOMAINusername" and ASPNET but it doesn't work, anytime I attempt to upload a file from theweb app the "access to the path '\ServerNameFolderTest.xls' is denied" appears. But if I do it
manually with "DOMAINusername" it works.

I am using NeatUpload file upload control: but issue can be generic i am thinking .. that's why posting on asp.net site...
Code works fine on my DEV machine (both file system and localhost) but when i deploy the code on Staging or Prod (on web server)... upload feature works fine but when I try to access the uploaded documents from staging server or Prod server, it says Access denied and cannot open the PDF document??
tried all the options but could not solve this issue... is this related to control or settings on my IIS...
before using NeatUpload(single upload) we were using microsoft upload control and it works fine in accessing the documents....
again upload works perfectly fine... the issue is accessing the documents..
I am using :
try
{
saveLocation = <paht name> + fileName;
FileUpload1.MoveTo(saveLocation, MoveToOptions.Overwrite);
}catch{<some return value>}
finally
{
FileUpload1.FileContent.Position = 0;
FileUpload1.FileContent.Flush();
FileUpload1.FileContent.Close();
FileUpload1.FileContent.Dispose();
FileUpload1.Dispose();
GC.Collect();

I'm currently working on an ASP.NET app that I inherited. There are a variety of file operations it has to perform and I'm getting and Access denied error when I attempt to create a directory.I've confirmed that the correct account is being impersonated and authenticated by checking WindowsIdentity.GetCurrent I've also confirmed that the account has full control for the parent folder of the directory I'm trying to create.The only think I can think of is that there might be an issue using a domain account rather than a local account. I'm not really 100% solid on how permissions work in this situation.Any ideas on why the account wouldn't have access? Is there any other code I could try to get more details about what is going on?
