My Win 7 pro laptop can see (and show in the network & sharing window) all the computers in the local private subnet but not others (ie., in the DMZ). I am logged in using an account with domain admin rights and I am able to find the other computers on the network via the "search Active directory" feature but I cannot access one computer (in the DMZ) using a standard unc desktop shortcut. Is it a local windows 7 permission thing? Any help would be appreciated. Thanks.
