Hi,

I am trying to write out XML data to a file and get an error. Specifically, I have a dataset and I want to write the dataset to a file. Then I want to email the file as an attachment. But when I create the dataset using WriteXml, I get this error:

System.UnauthorizedAccessException: Access to the path "C:\WINDOWS\system32\test1.xml" is denied.

The ASP.NET process is not authorized to access the requested resource. For security reasons the default ASP.NET process identity is '{machinename}\ASPNET', which has limited privileges. Consider granting access rights to the resource to the ASP.NET process identity.

Even if I call the file "c:\test1.xml" I still get this error so it has nothing to do with the file name. I understand that the process is not authorized. So I have more of a general question.... how does a web page write a file? Where is the file being written? On the users PC or on the web server? If its the web server, then is there any reason why my process should not have privileges? HOw does one go about setting these privileges? If on the users PC, is there some temp directory I should be using that will always have access?

Please forgive my ignorance... total beginner here!

Thanks,

Karen Healey
