What a great little freeware application. Seconfig is only 37K in size and can be right from the location that you decided to unpack it to. The freeware has three main functions: Restrict Lan-like access, Service settings and TCP/IP settings. You may disable netbios, SMB and RPC over TCP/IP in the first, those are major entry points for worms and hackers.
The service settings makes it possible to disable the remote registry service, the messenger service, SSDP discovery service and that IPSEC Services are started automatically.
The TCP/IP settings finally allow you to change the following entries: Drop all incoming IP source routed packets, Disable automatic detection of “dead” gateways, Disable IRDP (all interfaces), Disable ICMP redirect and Disable ports 1025 to N.
Click on help if you would like to recieve more information for every entry that you can change. I suggest you know what you are doing before you make changes to the system. Seconfig will change settings in the registry, it is of course easy to undo those changes by simply starting seconfig again.
If you click on status you see a list of all open TCP/IP and UDP ports and if Netbios, SMB and RPC over TCP/IP are closed or not.
