Issue: I am running into an issue with an image I have that is preventing me from efficiently activating the PCs that I have after deployment of a custom image. Whenever I attempt to do a MAK Proxy Activation, I have to disable the Windows Firewall on the client PC in order for the activation to take place. Prior to disabling it, I have been able to ping between the two computers without any problem. Scenario: Attempting to do MAK proxy activation on a Windows 7 Professional image with a Windows Server 2008 that has MDT 2010 and WDS using the Volume Activation Management Tool. The image is nearly perfect with the exception of two minor things, but aside from this and a password issue, it is golden. Research: I have done some research on line and it looks that WMI must be enabled and allowed through the Windows Firewall on the client in order for the MAK activation to occur. I am in the process of checking this right now, but I wanted to confirm that you do need WMI enabled and permitted before rattling my mind on what is preventing the access. Optimal Solution: One that doesn't require me to re-do the entire image. If at all possible, I would like to avoid re-doing the image just because I need to change one thing. Is it possible to insert the rule that may be needed using registry edits? I have found where I can add certain ports to the firewall profiles through netsh advfirewall command, but I'm not only unsure of what ports are needed, but also the scope and any other necessary parameters for this. I thank you all in advance. Just so it's clear, I have done some research all over the net on this but haven't found anyone with my issue. Also, I have looked through both the firewall addition and the WMI requirement prior to posting this. If I overlooked something, please let me know. Thanks! --Dustin
