NetScanTools 4.x Problems and Solutions
The information below is provided for historical reference
- Problem (all versions): Whois queries
for '.org' either fail or produce useless results. The
problem was the whois servers reallocated responsibilities
for reporting information. Posted February 5, 2003.
Solution, NetScanTools Pro 4.x only: In
whois setup, enter whois.pir.org in the Step One .com, .net
Whois Server edit box. Then do your '.org' query. After you
are done with the '.org' query, return the Step One Whois
Server back to the original server.
- Installation problem (NST all versions, Windows
NT4/2000/XP only): While installing NetScanTools
from a CDROM, you get most of the way through the
installation, then see an error message 115 and the
installation aborts. Posted 12/20/02.
Logout and relogin as an Administrator privileges user.
NetScanTools Pro requires administrative privileges for
certain functions to work correctly.
- Problem (NST all versions, Windows XP only):
NetScanTools when run on Windows XP is unable to sort out
NetBIOS (Windows) computer names returned to it during
NetScanner sweeps. XP's netbt.sys fails for multithreaded
NetBIOS name responses. For more info, see Microsoft
Knowledge Base article Q317936.
Install Windows XP Service Pack 1 or greater
NetScanTools 4.23 trial version crashes
on Windows ME - trial or registered - what now?
The trial wrapper around NetScanTools 4.23 does not interact
properly with Windows ME (no other OSes are affected). The
solution is to use a later version of NetScanTools and do
not use Windows ME for anything.
- Problem: the tabs -> Ping, Traceroute,
NetScanner, NetBIOS, Database Tests, shows only a blank
results area. There are no apparent columns and no results.
Solution: Press the Autosize button on the
- Problem (all NST 4.x versions, any operating
system): Incorrect reporting of TCP ports 25 (smtp)
and 110 (pop3) as being active on a target system when there
are not really any services running on those ports.
Symptoms: Unlike normal connect responses to these ports,
you do not receive any login banner data back. These ports
always appear no matter what IP you are scanning even if the
IP does not exist.
Solution: You are
most likely running an antivirus program like Norton
Antivirus 2002 that has the capability to scan incoming and
outgoing email for viruses. This is a good feature to have,
however, not when you are running a port scan of another
computer. Simply disable email virus scanning on your
antivirus program. On Norton Antivirus 2002, this can be
done by selecting Options on the main window, then selecting
Email under the Internet heading and unchecking the boxes
under What to scan. Certain firewalls may also produce false
positives too on other ports. You may need to consult your
firewall documentation for specific fixes. Port Probe
(scanning) will always work best when there are no firewall
or other filtering devices/software between NetScanTools and
the target system.
- Problem: NetScanTools 4.x will not
start on Windows 95. There is an error message about
being unable to locate ws2_32.dll or NetScanTools 4.23
may report that it cannot load nstmtspt.dll, error 1157.
This is because old operating systems like Windows 95 do
not include support for Winsock 2 without an upgrade.
(You might also consider upgrading to a newer operating
Solution: You do not have
Winsock 2 on your system, you must download and install
the newest Winsock 2 update for Windows 95.
- ANNOUNCEMENT, Friday 1/14/00. This
ONLY affects downloaded trial copies of version 4.0--it
DOES NOT affect CDROM copies (or version 4.02). It has
come to our attention that a serious compatibility
problem exists between NetScanTools 4.0 and the trial
wrapper that protects the program and imposes the 30 day
trial. This problem manifests itself in different ways
depending on the operating system. It usually shows up
when you use Port Probe or NetScanner. On Windows 95/98
you will see allocated memory growing until you see a
Failed to Initialize... (0010-0016-0120). On Windows NT,
virtual memory will be used until either the program
crashes with either a standard crash message or a Dr.
Again, we want to stress that this
only affected downloaded copies of NetScanTools 4.00.
There are NO known memory allocation issues in the CDROM
versions of NetScanTools 4. The CDROM version 4 and
downloaded version 4.02+ are VERY STABLE. NetScanTools
Pro 200x was NOT affected by this issue.
above issue was resolved on 2/7/00.
- Problem: NetScanTools 4.00 will not
go beyond the "Try" button on Windows 95. There is an
error message similar to:
GetDiskFreeSpaceExA could not be found in dynamic
KERNEL32.dll Error code: 127
Solution: This issue was resolved in a later
