Start Batch Job From IIS / Start Exe File With System.Diagnostics.Process.Start With Another Account Is Disabled?

Oct 28, 2010

What is the right approach when users (authenticated domain admins) should be able to start batch jobs (usually exe files) from an IIS (7.x) aspx (c#) page? This is an intranet site. The batch jobs have to run on the web server as Domain Admins. The website pool is executed by network service or some similar restricted account in AD.

Approaches I can think of (and their disadvantages):
1. Start exe file with System.Diagnostics.Process.Start with another account. This feature is disabled in IIS 7.x, how do I allow it?

2. Create a sheduled task and call scheduled task-api. This unmanaged dll is giving VS compiler warnings because it's unsafe to call from managed code.

3. I suppose there's a better approach, because the previous suggestions doesn't appear safe or robust.

DataSource Controls :: Generates Unspecified Error On Opening File On Production Server

Jan 5, 2010

I have an application that uploads an Excel .xls file to the file system, opens the file with an oledbconnection object using the .open() method on the object instance. The upload and writing of the file to the file system works fine but I get an error when trying to open the file on our production server only. The application works fine on two other servers (development and testing servers).

string connectionString = ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + ";") + "Extended Properties="Excel 8.0""
OleDbConnection connection = null;
connection = new OleDbConnection(connectionString);
connection.Open();

The exception comes on production server at connection.Open() some times, when I reset the asp.net worker process it started to work but after some hours/days It occurs again. how can I fix this issue which comes in production some times but very irritating, or there is some other work around.

Web Forms :: "No Application Is Associated With The Specified File For This Operation" Error When Trying To Open File With Process.Start()

Oct 11, 2010

I have a folder called GUI. Inside GUI thers another folder called PDF and inside this folder, there are some PDF files. This folder (GUI) is uploaded to the server too. Then I have a WebForm with some ImageButtons. When I click one of these ImageButtons, I want the file to open in a new tab. I tried with the following code:

C# - Start The Bat-file At Web Server Side?

Mar 30, 2011

I need to call a console application to load data into another desktop application on the remote server that located within the corporate domain.

Users will enter the web page and upload data to asp.net web server, which after transformation should call that console application. Users are located remotely and do not have any other access except the web server.

I decided to lower the security web application context and let the asp.net working process to start the console application on the current IIS 6.0 web server

What I have done:

I changed the security account for the application pool for Local System;

I added ASPNET Account and IIS_WPG IIS Process Account to Administrators group;

I added "Allow service to interact with desctop" for "IIS Admin Service" and "World Wide Web Publishing Service" processes and restarted the machine;


I tried to start BAT-file at server side through the test page code-behind, but failed:

[code]...

The error was "access denied".

VS2010 Error: Unable To Start Debugging On The Web Server

May 20, 2010

I get error message "Unable to start debugging on the web server" in Visual Studio 2010. I clicked the button and followed the related suggestions without success.

This happens with a newly created local ASP.Net project when modified to use IIS instead of Cassini (which works for debugging). It prompts to set debug="true" in the web.config and then immediately pops up the error. Nothing shows up in the Event Viewer.

I am able to attach to w3wp to debug. It works but is not as convenient as F5.

I also have a similar problem with VS2008 on the same PC. Debugging used to work for both.

I have re-registered Framework 4 (aspnet_regiis -i). I ran the VS2010 repair (this is the RTM version). I am running on a Windows Server 2008 R2 x64 box.

I do have Resharper V5 installed.

I simply want to create one file and then delete it, means I want to access one file subsequently. I am getting the very familiar error as shown in title. (Process can't access the file,) I have tried using file stream and all other stuff that I found from Googling but no success so far. Does any body have small and neat solution? in short, I would like to run the following statements without any error.File.Create("C:\hsp1.txt");

File.Open("C:\hsp1.txt", FileMode.Open, FileAccess.Read, FileShare.None);

DataSource Controls :: How To Configure To Allow Windows Services Running On The Web Server To Access Sql Server

Jan 14, 2010

We have a cient we are stting up that has 2 separate physical servers, one that is the web server the other the database server. Using impersonation we have been able to get the website to connect and retrieve data from the sql server so that part is not an issue. The problem is I have a windows service application that must be installed on the web server (as it process files downloaded to an ftp site) and it must be able to connect and write to the sql server as well.We tried adding a system.web block with the impersonation stuff to the app.config file which of course did not work. Can anyone tell me what/how we need to configure this properly?

Security :: Upload File Access Denied "Server Error In '/' Application"

Aug 25, 2010

Server Error in '/' Application. Access to the path 'c:InetpubEnewsAttFilesemploy-e-header2.jpg' is denied. Description: An unhandled exception occurred during the execution of the current web request. Please 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 'c:InetpubEnewsAttFilesemploy-e-header2.jpg' 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.
