I want to make a little program, that checks wether the computer is attached to the network or is working as a standalone. If not attached, the computer has to take action, if attached, and during operation disconnected, again, action is neccessary. I do not want to transmit any signal, so i was thinking of a programm which reads the NIC signal activity. It would be nice to check as soon as the computer boots, but during operation, it has to pol too.
In the company i work for, computers run with Win 95. It is determind in the policy that network valdidation is active. Some 'smart' users decide to disconnect the computer, gain access, install (illegal) software and re-attach the computer. Result : Unknown software on client pc's, virusses (record is 97 at one pc !) etc. And nobody knows who did what. Disconnecting Drive's did not help since some 'real smart #sses' have parrallel zip drives.... aaarrghh (i am work as a system administrator at a school...)
