My network scenario is:

Two location connected each other through Wireless towers. 1st network ip address are 10.10.10.1 to 10.10.10.150 2nd network ip address are 10.10.10.200 to 10.10.10.254

Both location using their own ACTIVE DIRECTORY (MS SERVER 2008) and share their data with each other network through file sharing.

My Problem is that every single client can explore the whole network. by simply typing \computername. i want to implement some restriction on network regarding file sharing.

i want to restrict 1st Network Clients to open 2nd network Computer or server. Is there have any Group Policy or Folder permission scenario that i implement on my both network..
