Dear Experts,
I am working on project for cyber cafe. Requirement is that when user login for net surfing then he can download/upload only 25 MB after that downloading/uploading will be disabled but net surfing will be on.

I did but it is capable for calculating download/upload data on net and local LAN through net shell command. I have no idea how can i disable downloading/uploading after 25 MB but net surfing should be on.
