Hi Experts,

Issue

Windows Firewall is preventing ping and RDP to all Windows 7 laptops. I need to create
a GPO or script to allow incoming ping & RDP to all laptops located on a VLAN /SITE from all machines sources
from 2 different subnets 172.20.3 and 172.20.4

Can you please provide all steps required to implement this GPO or script?

Also, I need to prevent any corruptions with the policies that are currently being applied to laptops. Any suggestions here?

My environment as per below

Windows 2003 Forest/domain functional level

Windows 7 SP1 os clients

McAfee 8.0  installed on all machines

I would like to see your recommendations to prevent any corruption because of new firewall gpo policy, and all steps required to apply the new gpo to allow incoming traffic for ping and RDP for computers from two different subnets

Hmm.  I don't have all your answers, but maybe some information that you'd find useful since no one has responded yet.

Just to cover the bases, you're probably already aware of the human steps to getting through the firewall as described here.
http://windows.microsoft.com/en-US/windows7/allow-remote-desktop-connections-from-outside-your-home-network

Then these folks fixed up their firewall with a nice GPO for Skype at their workplace and the method should prove useful to your application.

Is this infinite universes away from what you're looking for?

Then, if you need greater control/security you could get a C++ expert to write your own WFP stuff as discussed here...
http://msdn.microsoft.com/en-us/library/windows/desktop/aa366510(v=vs.85).aspx

from that page click "using windows filtering platform"  then click "Permitting and Blocking Applications and Users" and the associated example C++ code for filtering by app or user is here...

also note in the left margin the example under "reserving ports."
