Grant permissions programatically to write files on remote server

[Carlitos]

Hi there,

I do not have much experience nor knowledge about security in ASP.NET nor
Windows, so I apologize if I sound naive in this question.

I developed a web application and a DLL that the web application uses. This
DLL moves files from the web server to a shared folder in a different server
in the intranet. It seems ASPNET user account can move some files but not
all types of files because it does not have enough permissions to do that. I
have read about impersonation and delegates, but still haven't found how to
make this work through programming. I am trying to get an example on how to
programatically grant (or get, or make it work) access permissions to move
all kinds of files from the web server to the remote server, either using
ASPNET or a domain user, or whatever options there are.

I appreciate any help, suggestions and examples given.
