I'm sure that there are a great many hardening steps which would provide an even greater level of defense... Two I can think of off the top of my head is to examine the following security options on each machine: "Additional restrictions for anonymous connections" - set to "no access without explicit anonymous permissions" "LAN Manager authentication level" - set to "Send NTLM response only" or stronger You can find both of these in Local Security Policy. (Exact names may vary a bit depending on which version of Windows you're running.) Perhaps someone else on this list can recommend a resource with a comprehensive list of such steps?

Now, to secure my network I have done the following: - all latest patches on all systems - every system has got a personal firewall (sygate) - every system has got a anti-virus software (up to date) - for WLAN: - WPA is activated - ACL for MAC- addresses is set, so that only my notebook can access the network - SSID broadcast is OFF Did I forget anything useful to harden this network? The problem is, that my neighbour also bought WLAN equipment *ugghh* so I really need outside and inside security! Thanks and a happy new year mosquitooth --------------------------------------------------------------------------- ---------------------------------------------------------------------------- --------------------------------------------------------------------------- ----------------------------------------------------------------------------
