You can use
net view \\computername
command to test a network connection. Net view command will
display a list of the file and print shares of a computer that is running
Windows 2000 is generated by establishing a temporary NetBIOS connection.
If there are no file or print shares
available on the specified computer, you receive a "There are no entries in
the list." message. If the command (net view
\\computername) does not work, use
net view \\IP
address of the remote computer.
If net view
works, but a net view attempt to the computer name does not work, the computer
name may be resolving to the wrong address.
To list all computers are running on the network, type net view only
(or net view /domain:domainname for each domain). That will show all
can contact an Internet resource directly, but "Ping" the Internet IP gets
"Request Timed Out". That is because
many organizations block the
return of ICMP (ping) packets as a security measure.
