Your solution *may* solve the problem that Thomas has but it does not
fit the one he actually described.

According to what he wrote, Thomas wants to check that the given Win2k
system is connected to a network. Being connected to a network does not
require that one is connected to the Internet. It also does not require
that a given URL can be resolved, that a given webserver is reachable,
or that a given URL can be fetched. It only means physical access to the
network.

To be precise even the assumption that TCP (IP) is used needs further
justification - in the given case by mentioning that Win2k is used and
not mentioning IPX, NetBIOS, or other alternative protocols that can be
used for networking.
