Security :: Cannot Run System.Diagnostics.Process.Start In Code Behind Under IIS
Jun 30, 2010
I can not run System.Diagnostics.Process.Start(@"wmplayer.exe") in code behind under IIS, - nothing happens, though I can do it successfully using Visual Studio ASP.NET Development server. I read topic http://support.microsoft.com/kb/555134 and made as recommended: 1) Made ASP.NET worker process run in SYSTEM account 2) Enabled IIS Admin Service to interact with desktop and rebooted serivce. - wmplayer.exe does not start, even its process does not start. I tried start notepad.exe and it partly works - process starts, I see only window frame, but not menu and can not interact with it. The other thing I tried is to put it under out-of-process (IIS virtual folder properties) and gave the process administrative rights (changed identity in Component Services): no result.

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.

I've written a aspx.net(C#) page that after the user has done what they do on the page they hit a Submit button. The Submit button
1) takes the work the users was producing on the page and writes it to a file.
2) attempts to execute a batch file.
The call to the batch file is executed via:
protected void Execute123EDI()
{
try
{
string File = @"c:80sAdminSendV80s.bat";
lblCancelled.Text = lblCancelled.Text + File;
Process proc = new System.Diagnostics.Process();
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.LoadUserProfile = false;
proc.StartInfo.UserName = "administrator";
proc.StartInfo.RedirectStandardOutput = true;
System.Security.SecureString secPass = new System.Security.SecureString();
string paswd = "123abc";
for (int i = 0; i < paswd.Length; i++)
{
secPass.AppendChar(paswd[i]);
}
proc.StartInfo.Password = secPass;
proc.StartInfo.FileName = File;
proc.Start();
FileStream fs = new FileStream(@"c:80sAdminSendV80sOutput.log", FileMode.Append);
StreamWriter sw = new StreamWriter(fs);
sw.Write(proc.StandardOutput.ReadToEnd());
proc.WaitForExit();
sw.Close();
proc.Close();
}
catch(Exception ex)
{
lblDebug.Text = lblDebug.Text + ex.Message + "<br/>";
}
If I watch the processes tab in Task Manager on the web server I see "cmd.exe" under the context of 'administrator' but it just hangs. For test purposes c:SendV80s.bat: copy c: oot.ini c:zzz.txt
If I logon onto the webserver's console and execute SendV80s.bat it works and exits without issue. But when I execute the same batch file via the Submit button it gets stuck executing in Task Manager/Process. I believe this has something to do with the fact that cmd is not running in a full environment/desktop context. I just noticed this on the actual console of the webserver (not in my RDP console but console 0 instead)
A pop-up box stating: CMD.exe Application error The application failed to initialize properly (0xc0000142). Click OK to terminate the application. And when I click on the OK button my ASPX page's WaitForExit is satisfied and the continues processing normally.

When I run System.Diagnostics.Process.Start from my console application it works but the same code when I run from my web service hosted in IIS doesn't work.
Is it some thing to do with ASP.Net privileges?? if yes how can I configure it from my C# code.

I am trying to use the unmanaged ImageMagick library in my ASP.NET application from the command line using System.Diagnostics.Process. Basically, users will upload an .eps file to the site, and then I will run the command line command to convert it into .jpg. This is the code I'm using to try and run the command:
Dim proc As New System.Diagnostics.Process
proc.StartInfo.RedirectStandardOutput = True
proc.StartInfo.RedirectStandardError = True
proc.StartInfo.FileName = "C:Program Files (x86)ImageMagick-6.6.1-Q16convert.exe"
proc.StartInfo.UseShellExecute = False
proc.StartInfo.Arguments = String.Format("{0} {1}", Server.MapPath("~/logo/test.eps"), _
Server.MapPath("~/certificates/temp/test-1234.jpg"))
proc.StartInfo.CreateNoWindow = True
proc.Start()
I am able to run this code just fine on our development Win 2k3 server, but not on our production Win 2k3 Server. I get the error "System.ComponentModel.Win32Exception: Access is denied". The main between the two servers is that the production is 64-bit and runs Plesk to manage multiple domains. I've tried adding rights asp.net user to the ImageMagick directory. The PS Admin says that in the case of Plesk, it's the same account that I use to access the site in VS using FPE. Does anyone know what I might do in order to allow this process to run on my production server?

I have developed a ASP.NET C# web page which connects to remote conmputer command prompt using PSEXEC.exe and executes some command where the output of the command will get copied to the page. It works fine in the VS 2005 IDE.
If the page is accessed via IIS from IE, the task PSEXEC.EXE appears in task manager of the server with the system account privilege after the method is triggered but nothing happens.
find my present settings in IIS and others:
1. APP Pool Identity to Local System (Predefined) and also to a configurable admin account.
2. <processModel userName="SYSTEM" password="AutoGenerate" /> in Machine.Config file
Also I've tried impersonasation in web.config file to an admin account.
Code Is:

We have a Page Method on a web page using ASP .Net. We tried to put in a trace statement using both System.Diagnostics and System.Diagnostics.Debug. In Visual Studio 2008, the break point is not even hit for the line, but other break points on other lines are hit.There is no output from either method that we can see.
There is also a Global.asax error catcher that works fine in other cases, but in the Page Method is not being catched.why a Page Method and System.Diagnostics do not play well together?

There is a Web Service installed on Amazon Server. Exposed WebMethod should start an executable. But, it seems that process (executable) started by WebMethod has not permissions to finish its job. If a WebMethod is called locally (using IE on Amazon VM) I can trace some events into log file placed on the path: C:\LogFiles. But, if it is called from remote machine, there is no even log files. Locally, on my machine all works fine.The question: is there any way or settings in IIS7 to allow to my WebService to create process that can do everything I want to do? In web.config file I added a line:
<identity impersonate="true" userName="USERNAME" password="password"/>
(userName and password are, of course, written correctly in the file).
Also, I tried to use impersonization as it is explained here, but there is no result. My process can't do its job, it cannot even trace actions into log file. Locally, on my machine, everything works fine.
how to change settings or whatever into IIS7?
EDIT: In addition to the main question: my WebService is not able even to create log files on the path: C:\LogFiles - although it is able if it started locally, but remotely there is no simple log file that contains some string. How to allow it to create simple text files?

I have a web app that needs to start an application. It works great when using the debug server from VS2010 but once I deploy the web app and use the local IIS 7.5 server the application process starts in the background (no UI just a process visible in the task manager). The process is owned by DefaultAppPool. I Added DefaultAppPool user & IIS_IUSRS group to the program folder permissions but still no luck.I've found this old link on this problem but the solution doesn't apply to IIS 7.5.

Im deploying my website onto my new server (windows 2003) from my local pc (windows 7) and my local homeserver (windows 2008) and have run in to a issue.
I have a process that starts up with the below code. It is passed a video file which gets converted.
System.Diagnostics.ProcessStartInfo StartInfo = new System.Diagnostics.ProcessStartInfo(Command, Parameters);
Them problem I have is on my new windows 2003 server it fails to work. No error or anything. Looking at the server and its taskmgr.exe I see the Process start but nothing happens.
Looking into it, everyone seems to say I need to have impersonate="true" in the webconfig which I do have, I currently have it set to the Administrator account which I use to log into remote desktop (I assume this is fine???)
<identity impersonate="true" userName="Administrator" password="********" />
This still doesn't work.. Looking in the taskmgr.exe the process is started with the username ="NETWORK SERVICE" ...

Dear ladies and sirs.
I have a .NET infra code running both within the IIS worker process and within a desktop client app. How can the .NET code determine whether it is running within an IIS worker process?
I know that I could check the name of the process (w3wp.exe, for instance), but I would like a more robust approach. I wish to make a side note. This is not a production need. I need this information to enable certain scenarios useful during the development and testing phase. Specifically to ease the testing of secure vs non secure configurations.

So, I have a webForm that has an ImageButton. This ImageButton has to open a file (said file is uploaded by the user in another web form. The file is saved to \serverNamefiles; it can be a doc file, pdf file, excel file).
So this ImageButton should open said file as you normally would. It works on debug, however when I publish my site, and run it from my localhost, it doesn't open the file. When I click the ImageButton it just does the postback and nothing happens.
The code for the ImageButton is just:
Process.Start(fileName);
fileName has the full path of the file I want to open, in this case it has: \serverNamefilesmyFile.pdf

Unable to start debugging on the web server. The IIS worker process for the launched URL is not currently running.I'm running Windows 7 64 bit, VS 2008 sp1.When I first try to debug I get the error msg above. I wait a few minutes (presumably some service is starting) and debugging will start but no breakpoints are recognized.Some of the things I've tried:Changing the binding of my site from a static IP to "*".
Enabled windows authentication.made sure localhost = 127.0.0.1 in the hosts file.The website was built under windows xp and whatever version of IIS ships with xp. My web config has no errors that I know of but might be missing something required for iis 7 (??)
