Is it possible to use a small .NET page to set folder permissions on some folders on the server where it resides? What is the code or objects that can be used for this? I am on Windows Server 2003.
Basically I want to hit the page with a GET or POST and have it run and check and/or update the permissions on a folder.
I am using windows authentication without impersonation on my company's intranet website with IIS7.
Under IIS7, what account is used to access the folder which contains my web app using these settings?
Would it be IIS_IUSRS? Or NETWORK SERVICE? Or another I don't know about?
how can we set grant or dynie access or permissions to folder by programming c# in asp.net?
View 5 RepliesI want to remove execution permission for one folder in the site.
For example:-
I uploaded files to one folder called "Downloads" .
so, user can download those file just browsing "http://localhost/downloads/uploadfile.wmv". But problem is once user uploaded ASPX page (default.aspx). then user can browse like this http://localhost/downloads/default.aspx". In that, if he wrote so code for removing files..!. So, I don't want to run the script in this folder, I just want to show that file as text output.
Note:- This I can handle by using my own code to display files(ASPX, ashx and ....). But, I want to allow the user to access directly to that file.

I wrote an asp.net application that I'm trying to run on a godaddy domain I bought. I need to read a file in a folder that I did not give read access to so that your average user cannot see in the informaion in that folder. I assumed that the asp.net program would have the same credentials as myself because server-side code. Turns out I am wrong. When I go to use the asp.net application it throws an access denied error saying that the ASP.NET user account has to be given permissions to access the folder.
After talking to two different tech support people at godaddy I've come to the realization that they are either dumb or lazy (or a combo of the two).I came across some code that you can put into the web.config file that would allow the asp.net application to impersonate a user, which would work great to use myself as the impersonated user. However it seems that godaddy cannot give me the name of the server that my domain is on (that's understandable) so I don't know what to put in the identity tag to get this to work.
Here is the code I found:
[Code]....
(of course I filled in the username and password with the correct info)
When I went to use it again it threw this error:
System.Web.HttpException: The current identity (PHX3username) does not have write access to 'C:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files'.
I am calling example.exe from asp.net web-page. Example.exe contains Process.Kill(), but I am not able to kill that process whenever Ill run example.exe from asp.net web page. I think i need to set some permissions for killing processes. What permissions must a user have to be able to succesffuly execute a rocess.Kill? Note : it is working when I double clicking on (example.exe), means its killing some processes

We have a web application that runs on a WIndows Server 2008 64 bits machine. The app's ApplicationPool is running under the ApplicationPoolIdentity and configured for .net 2 and Classic pipeline mode.
This works fine up to the moment that XmlSerialization requires creation of Serializer assemblies where MEF is being used to create a collection of knowntypes.
To remedy this I was hoping that granting the ApplicationPoolIdentity rights to the ASP.Net Temporary Files directory would be enough, but alas..
What I did was the run the following command from a cmd prompt:
icacls "c:windowsmicrosoft.netframework64v2.0.50727Temporary ASP.NET Files" /grant "IIS AppPoolMyAppPool":(M)
Obviously this did not work, otherwise you would not be reading this :)
Strange thing is that whenever I grant the Users or even more specific, the Authenticated Users Group those permissions, it works. What's weird as well (in my eyes) is that before I started granting access the ApplicationPoolIdentity was already a member of IIS_IUSRS which does have Modify rights for the temporary asp files directory.
And now I'm left wondering why this situation requires Modify rights for the Authenticated Users group. I thought it could be because the apppool account was missing additional rights (googling for this returned some results, so I tried those), but granting the ApplicationPoolIdentity modification rights to the WindowsTemp directory and/or the application directory itself did not fix it.
For now we have a workaround, but I hate that I don't know what is exactly going on here, so I was hoping any of you guys could shed some light on this.
I'm uploading an Excel file and then reading data using oledb connection in asp.net but I'm getting the following error: The Microsoft Jet database engine cannot open the file ''. It is already opened exclusively by another user, or you need permission to view its data.

The excel file is uploaded successfully and present in the folder.
Can I use LINQ to SQL and have a user log in, and with that login be restricted to certain parts of the database.. basically having access to information located under their particular customer ID number.... how would I get the 'session' to follow them throughout the website without having to login each time the database is tapped for info...?
View 1 RepliesI am doing some testing and want to find out best practice for creating a new user to assign to an appPool. I know that the default ASPNET account, on IIS 6.0, is very low permissions. For experienced folks, what are the bare permissions required to grant this new user? Yes, I am aware that various NTFS rights are required for different operations, such as reading outside of the application path, writing to the NTFS share, etc. I am just looking at a base install.
Dino Esposito wrote in Chapter 15 of Programming Microsoft ASP.NET 2.0 - Core Reference that the following directories would need the respective permissions:
.NET framework root - read/list Temporary ASP.NET folders - full GAC - read Windows System32 - access/read App root - access/read Web site root - scanWhat else would I need to set up beyond this base configuration as far as rights are concerned? If anyone does this regularly, do you have a script to do this automatically?
I've recently installed VS 2003 to work on an existing web project (I already had 2005 and 2008 installed), but I'm getting an annoying problem when I try to run it. I get a browser page with an error message of:
Code:
Required permissions cannot be acquired.It then pinpoints the problem as being in line 198 of my machine.config, which is:
Code:
<add assembly=*/>
I've changed the ASP.Net version to 1.1.4322 in the appropriate places, and other people in the team can run the project happily using an identical machine.config (they used a copy of mine).
I've got a routine that tries to import files from an import directory, spitting them out to an Error directory if the import fails. The Error directory is shared and users have access permissions to delete files in there, so they can try to fix the problems and then move the files off to the import directory again. I use File.Move to move the files to the Error directory and this is working fine, apart from the permissions - it seems to revert to a default set of permissions, rather than the directory's one, and so the users can't remove the files - how can I reset the permissions on the file to those of their containing directory? I've tried poking around with SetAccessControl and SetAccessRuleProtection but I don't seem to be having any luck?
View 1 RepliesI have an ASP.NET 4 site that uses the new SQL CE 4 CTP. The site works fine locally (IIS 7.5 on Win7) and fine in Server 2003/IIS 6. It fails when deploying to IIS 7 on Server 2008. The error I get is:
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
The interesting thing is if I switch the app pool user from its default user to LocalSystem, everything works great. So clearly there is a permissions problem somewhere.
Long story short, does anyone know what special permissions need to be set when deploying a SQL CE 4 database? (BTW, we have already set r/w access on the db itself and on c:windows emp)

The website has a separate application pool defined for it running under the Network Service account. I have checked the settings for the virtual directory for the application but nothing seems wrong. I have tried defining the trust level in web.config to full trust but this does not fix the issue. I have looked into defining the trust level for the application through the machine.config file but I am unsure of how to proceed with this.
We have a small XBAP file upload app that we are having trouble deploying. We were getting security errors when we were pushing this application that we don't get when running in our development environments on our machines. We gave the XBAP app full permissions and still got errors. Then we created a personal certificate and were able to get this to work. But that means we have to load a client side certificate for each and every machine that wants to run this which is ridiculous.

I have a simple photo album. I have some catories in db and corresponding folders. For example, when user creates a category called "Asp Net" in db then a folder called "AspNet" is created. Then user can upload photo and all photos are displayed as thumbnail. No photo is saved in db, they are directly saved lets say AspNet folder. I just fetch filelist from intended folder and list them. However I want user to be able to update category name or delete it. To keep consistency, corresponding folder should be updated or deleted. But when I try it throws exception: Access to the path 'xxxxx" is denied.
View 1 RepliesI want to create a folder to store some web controls, so the site structure doesn't have a zillion files in the root.
Except that if I create an ordinary folder, that folder is also visible on the web site. MSDN said you cannot put it in App_Code, and it doesn't really make sense to put it in other special folder like App_Data or App_Theme.
