Gateway and member "Green" and can Chat but no ping or file/folder access

[SSITECH1]

I have the gateway on a Windows 2008 Server that is also the DHCP and DNS server for our school system's LAN, but the Hamamchi member (a Windows 7 PC) could not get an IP address. I switched to using the Gateway to assign IPs from a static pool and that worked (although I'd rather have had DHCP do this). The gateway and member icons both went green on both ends, the yellow triangle ! icons all went away, and they can can chat in both directions, but cannot access resources on the gateway LAN or ping either direction. I have turned off the firewalls at both ends, at least temporarily, I have disabled UAC at both ends, and I have unblocked Proxy/Anomizer on our OpenDNS account. They are both showing direct tunnels and all appears to be correct? What else am I missing? I've been working on this for two solid days and reading every related post I could find. HELP!! Please!!

In the Network and Sharing Center on the client, how is the network represented?  (Home, Work, Public)

[SSITECH1]

On the member PC (Windows 7), the local network is a Domain network, the Hamachi is a Public network, and the Hamachi ###-###-### is a Public network.

That would be the problem then.  Public networks are not allowed file sharing in Vista/7 by default.

I have enabled file sharing on Public Networks as a test and I still have the same problem. Any other ideas? I am suppposed to demo a couple different types of VPN for the IT Director of the Meriwether School System next week and I was hoping Hamachi would be one option for them. They are looking to do a phased VPN implementation with initially just the board members and financial people, the add the teachers, and then add the teachers aids so eventrually they will be looking at up to 256 connections. Thanks.

Checking the firewall is really the only suggestion I have at this point.  Firewalls tend to block file sharing over newly added adapters if they were marked as public to begin with, and will not revert this setting when the adapter is trusted.

One firewall that can be particularly tricky is the new Norton Internet Security, or Norton 360.

In that firewall, you will want to go to the Tasks section, and choose Network Security Map.  This will enable a very usefull feature (as far as I am concerned) and will allow you to trust the network adapter itself.

By default, Hamachi does not dictate what can and cannot be sent over it, so out of the box, you should be able to do anything that your Firewall and OS allow you to.

try to put hamachi on every single client under home network. reboot and try it again.
