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.

Q. My 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 the Internet"?

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 hostnames.

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).

Q. I 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 Advanced Mode paragraph in the NBScan chapter.

Q. I 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 account.

Q. When 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.

Q. When 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 share.

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 ping computername in the DOS prompt. If the computer is successfully pinged, you can use Essential NetTools to connect to it.

Q. When I select the Open Computer command or try to mount a share, the program displays an hourglass and nothing happens for some time.

A. Well, be patient :-) Usually it takes several seconds to establish a connection.
