You need to grant the ASP.NET process identity the write permission to the folder which contains the text file .txt. For more information, you can see: Process and request identity in ASP.NET[^]

if i want to send this file to another machine which is not the request machine is that possible ? I am Entry level person

Your question IMO is quite vague. That all depends on what you need, so the answer might yes or no. Could you be more specific about what you want to do?

i have a windows application can make a request to the webservice, then the webservice deals with these request data and be able to create a Txt file with these data then send to another machine. if you have Email, i can pass some graph to you as well! I am Entry level person

+ If your web service is directly trying to save the file in another machine, then basically the account that your service runs under should have the permissions to that remote machine. + Another way is that you have another process running on another machine, and this process is resposible for receiving the data sent from the web service and saving it to disk.

Could you post it here so that people can give you a hand or a better idea?

There is a Windows application sitting on Client A can make a request to the server which has a web service on it, then the server can create a Text file send to B and C, there is another windows application sitting on B and C which can read the text file then deal with the data included in the Txt file, and talk to database. i think for me the second solution is better. but how it works ? Can you give me some specific thing such as functions and reading material i can have a look and read?1 I am Entry level person

In fact, there are a couple of options to do that + The windows applications running on the machines B, C can host a web service that is resposible for receiving the notification about the text file. You can read the article[^] to see you can run a web service without IIS. + You can use the .Net remoting here. Basically, the window application host an object that the web service can remotely access. Once the text file is genererated, the service can notify the window applications via this object. For more information, you can read the documentation: .NET Remoting Overview[^] + The web service can use the Messaging[^] to notify the window applications about the text file .txt + The window applications can listen to a change made to a common/shared directory that the web service is able to save the file. If the file is generated, the applications can detect that and read the file. Just some ideas.

Hi there, From the error message, I still might think that the account that your web service runs under does not have the proper permission to the folder. Can you tell me in details how you have granted the permission to the ASPNET account (or NetworkService if you are using IIS 6). Are you sure that you select the right account to grant the permission?
