In this chapter
you can find answers to some of the most frequently asked
questions. The latest FAQ is always available at http://www.tamos.com/products/nettools/faq.php.
firewall software warns me that Essential NetTools is "attempting
to access the Internet." I am aware that some sites are able to
track users by collecting the information sent by their programs
via the Internet. Why does Essential NetTools "attempt to access
A. What alerts
your firewall is the attempt to resolve IP addresses to hostnames,
which is necessary for showing the hostnames in the NetStat tool.
Since Essential NetTools has to contact your DNS servers to make a
DNS query, it inevitably triggers the alarm. You can disable this
feature (Settings => Options => Disable DNS resolving), but
in this case the NetStat table will not be able to show you the
Q. I try
to use NBScan to check my own IP address, but I can't see my
computer's name table.
A. This most
probably means that your computer either doesn't offer resource
sharing or it has Winsock version 1 originally shipped with Windows
95. In the latter case, consider using nbtstat -A xxx.xxx.xxx.xxx
instead, or upgrading to Winsock version 2. This limitation doesn't
apply to viewing other computers' name tables (Winsock 1 works just
as good as Winsock 2), nor to NetAudit (you can audit your own
computer with it).
check the address xxx.xxx.xxx.xxx by NBScan and get no results, but
nbtstat gives me the name table.
A. Two possible
reasons. You either set a very short timeout and the response to
the query couldn't reach your computer in time, or you are not
using the Advanced Mode. In Advanced Mode, the program lists 100% of
the computers nbtstat can potentially list. Please read the
Mode paragraph in the NBScan chapter.
check the address xxx.xxx.xxx.xxx by both NBScan and nbtstat and
get no results. The person to whose computer this address is
assigned checks the same address (his own) and gets his own
computer's name table. Why can he see it and I can't?
A. There is a
firewall or some other packet-filtering device between his computer
and your computer. Certain packets may be rejected because of the
firewall settings. Also, some Internet Service Providers filter
packets without informing their customers. If that's the case, you
may want to audit the network from a different
I try to mount a share, I receive the "The network is not present
or not started" error, but I'm connected!
A. You are
probably using Dial-Up Networking and you forgot to check "Log on
to network" box in the connection properties.
I try to mount a share, I receive the "Shared Resource Not Found"
error, but I know I typed the correct path to the remote
A. Make sure
that the computer name is present in the lmhosts file and that it's
a unique name in the file. There should not be 2 or more computers
with the same name in the lmhosts file. You can check whether your
computer is capable of "understanding" the name by typing
computername in the DOS prompt. If the
computer is successfully pinged, you can use Essential NetTools to
connect to it.
I select the Open Computer command or try to mount a share, the
program displays an hourglass and nothing happens for some
A. Well, be patient :-) Usually
it takes several seconds to establish a connection.
