remote accessing

[KAMAL]

hi all,
I want to access remote system files and i want to modify them from
my system using asp.net(C#.net VS2003). If a request is sent to the site i
designed , on client system (where the request came to my site) the software
has to be installed (client application to get the files of the client
system and client system information ) .
Using that software i want to access client system from my system.

Thanks in advance.

Regards,
Kamal.
