Hi,
I have one requirement sending a news letter for subscribed users for every month, when admin uploads a new pdf file from the admin site. Here subscribed users are nearly 5lacks users.
So, I created a windows service for background process. When admin uploads a new pdf, click Send button then invoking Window Service and sending mails to all the users by this mail service.
This is my code in web application

C#

private void StartServiceByName(string serviceName)
        {
            ServiceController serviceController = new ServiceController(serviceName);
            try
            {
                serviceController.MachineName = ConfigurationManager.AppSettings["ServerName"]; //this is my computer name "dt-corp-pms-04";
                serviceController.ServiceName = ConfigurationManager.AppSettings["ServiceName"]; //This is my Service name"Service1";
                serviceController.Start();
            }
            catch (Exception ex)
            {
                ExceptionLog objExceptionLog = new ExceptionLog();
                objExceptionLog.SaveException(ex.ToString(), ex.Message);
                if (serviceController.Status == ServiceControllerStatus.Running)
                    serviceController.Stop();
            }

        }

and in my web.config I added key also

<identity impersonate="true" />

This is working fine in my local machine when I am testing my web application, the windows service is running, and sending the mail to all the users.
But When I deployed this web application on my client server, I am getting the message Can not open "MyService" Service on computer "MyClientComputerName"
I hosted my web application and installed my windows service on my client's same machine.

Please help me.

Solution 2

The issue can arise if the server is in Shared Hosting environment. Please make sure that the application you have hosted is a Full Trust application. I believe interacting with the services is like a Admin task. Most, if not all hosting providers keep the application in the medium trust levels.

If you have a dedicated server, you need to configure an account which can enable and disable services and then provide its credentials in the identity tag like this:

XML

<identity impersonate="true" userName="accountname" password="password" />

On your local machine it works fine because most probably you are running Visual Studio with Administrator rights.

saichaitanya.kumar 4-Jul-12 2:14am

when I dont add <identity> key in web.config, the web application can not open the "Service" on the "ServerName",(it is working fine in my local mechine, but failed on the production)
if i add <identity> key in web.config with my production server username and passowrd, totally my web application gives yellow pages in live, giving red heighlet on the <identity> column.
Plz help me what i do, Can i add any other properties to serviceControler in web application?

Pankaj Nikam 4-Jul-12 2:18am

When you dont add the keys, it is obvious that you get the exception.
I did not get the part where you mention that after you put the identity tag, what red highlight does it give? Can you post a screenshot of it?

saichaitanya.kumar 4-Jul-12 3:02am

when i add identity key in web.config, i am getting the error , so that the reason I remove the identity key in web.config. Is it mandatory to run windows service through the web application?
