ModemLockDown disables access to the Internet until a supervisor or parent is present to enter the correct password. It can automatically disable Internet access on system startup, or you can allocate one-hour access blocks, on a day-of-the-week basis, for individual users. Dial-up modems are locked, so no malicious programs can take over and dial out unexpectedly. Supports DSL\Cable (2k, XP, 2k3 only) and Dialup(98, ME, 2k, XP,2k3)
