When I tried to do connect to the desktop again after restarting notebook2 (domain), a firewall message popped up on the desktop (ZoneAlarm has blocked access to the NetBIOS.... access to TCP Port 445 from TCP port 1062 has been blocked). I turned off the firewall and couuld see the the share folder on the desktop from notebook2. It seems like in the home version of zonealarm, one cannot creat a trust network to allow access to some ports on a trusted network. I guess I will have to find a different firewall. Another question: how secure is this network? I have a 32-character WEP key for the secured wireless connection. I know I am mixing the two up, but is my file share network also secure such that no one outside can look at these files? I appreciate your help. There was no way I could have done this on my own!

There was no way I could have done this on my own! I'm glad to help. That's the purpose of these forums. First, ZoneAlarm Free can and should be configured to allow file sharing. You simply identify the Local (Trusted) Zone to include the subnet. It's in there, I promise. If you're behind a NAT router, you're safe from Internet threats. A personal firewall protects you from unknown threats from other computers on the subnet, ie behind the router with you. Both a NAT router, and a personal firewall, are critical components of a layered security strategy. <http://nitecruzr.blogspot.com/2005/05/please-protect-yourself-layer-your.html> http://nitecruzr.blogspot.com/2005/0...ayer-your.html Regretfully, I must warn you that using WEP WiFi protection is better than nothing, but very little better. WEP is simply not adequate protection. You need WPA, at a minimum, and WPA2 if your equipment supports it. <http://nitecruzr.blogspot.com/2005/05/wep-just-isnt-enough-protection.html> http://nitecruzr.blogspot.com/2005/0...rotection.html <http://nitecruzr.blogspot.com/2005/05/setting-up-wifi-lan-please-protect.html> http://nitecruzr.blogspot.com/2005/0...e-protect.html -- Cheers, Chuck, MS-MVP [Windows - Networking] http://nitecruzr.blogspot.com/ Paranoia is not a problem, when it's a normal response from experience.

I have NAT enabled. Inside NAT, of the many options, there is UPnP setting which seems useful but I am not sure. Then there are ALG settings, all of the options are enabled. The router also has a firewall, but I have not enabled it as of now. Coming to the Wireless configuration. To someone in the non-networking world, as soon as I saw 128-bit encryption in WEP, I assumed it was secure like a brick wall. Thank you for pointing me in the right direction. I can also educate my friends who insist on leaving their wireless networks unsecured saying that no one can "watch" over their data as it is being transmitted. NOw, the router can also have WAP pre-shared key and WPA radius encryptions. In both of these, there is something called WPA Unicast cipher suite with three options WPA (TKIP), WPA2(AES), and WPA2(Mixed). I tried setting up WPA pre-shared key with Hex 64 character pre-shared key format, but to my surprise the pre-shared key field takes only 63 characters and gives an error (to enter 64 characters) when I press apply. I have not been able to figure this out. Also, on the notebook accessing the wireless network, it seems the maximum key length can be 26 characters. When I enabled the WPA2(AES) with a 26 key Passphrase, I could not connect the notebook to the wireless network (even after changing the settings of the wireless connection from WEP to WPA-AES). Dont know why. Also wondering if I can setup the WPA radius encryption and the IEEE authentication. Basically, I bought the router and picket the first set of settings that worked. A resource (book?) which explains all the various options would be very helpful. I am still trying to figure out the zone alarm thing.
