WCF / ASMX :: How To Create A Folder On A Network Share
Mar 7, 2011
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 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?

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.

If you use anonymous access + impersonation of a windows domain account to access a file on a network share, is the password sent in clear text?

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'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.

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'm searching an answer to this question on the web for 2 weeks unsuccessfully.I'm sure I'm not the only one to wondering about that! I have two web projects MVC2: a FrontOffice and a BackOffice.
The user has to be able to upload some image in the BackOffice, which will be display on the FrontOffice and vice versa. How can I share an image folder between these two projects? Has the folder to be necessary in the solution or can it be somewhere else on the server? My team and I are working with TFS.
I want to create an image folder in which we can write and read from frontoffice and backoffice. But I don't want to have to do a "get latest version" everytime someone is adding an image in the folder. I would like to create a folder on the server we can access from the backoffice AND the frontoffice with reading and writing rights in real time. I'm not sure to be very clear.

In this asp.net web application, users can upload files to the server through a web interface. All the uploaded files are save in a server side folder. If I want to create a new win form desktop client (actually, its a WPF application) which can be used to upload files to that same server side folder as web interface does, how can I share that server side folder with that win form client?

I've developed a file browser that will browser a different server shared folder. In order to get this working I'm using the unc path (\ServerSharedFolder) to return the files/folders. I've also added the following to my webconfig to get around the security <identity impersonate="true" userName="domainadmin"
password="password" />
It's simply a file browser, no create or delete functions will occur. The solution works and what I want to know is that this the safest way to do this? or the best way? I did try to use a virtual directory instead of unc path but asp.net would support this.

I need to iterate through a server share and list every file within every folder and write each file name with all of its attributes into a database table.I assume that using the FileInfo class and all of it's properties (CreationTime, DirectoryName etc etc) is the best way but I have no idea of how to start.I'm starting to create a web app

i have a situation where i need to develop a web system where sys. admin can create a shared folder in server and set who can access the shared folder programmatically.
i've manage to find example to create a shared folder from here:[URL]
and i also manage to find example to add user and set folder Security setting from here:[URL]
My problem is how can i add user in the Sharing permission setting since it is a shared folder. Default sharing setting is set to 'everyone'. This mean anyone in my company can browse to the shared file unless i set everyone security setting. I want to remove "everyone" and add users based on the user that i've already add at Security setting.

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 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.
