NetScanTools 4.0 - 4.31 Support
- We no longer actively support the 4.x series.
It was replaced by the 5.x series in July 2003. The last
version was 4.31. If you are a registered user,
please contact us by email
for the software.
- How do I uninstall a trial version of NetScanTools?
Removal instructions are here.
- Problem (all versions): Whois queries for '.org' either fail or
produce useless results. The problem is the whois servers have yet
again 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. We will be automating
this process soon in the next release of NetScanTools, but not for
the earlier versions 3.x.
- 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
Solution: Logout of Windows and relogin as an Admin 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.
Solution: Install Windows XP Service Pack 1
NetScanTools 4.23 trial version crashes on Windows ME - trial or
registered - what now?
Solution: 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.
- Problem: any of these 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 affected tab.
- 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 system!)
Solution: You do not have Winsock 2 on your system, you must download
and install the newest Winsock 2 update for Windows 95
Older NetScanTools 4.x version problems long since corrected in
- ANNOUNCEMENT from 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. Watson dump.
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.
The 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:
Export function: GetDiskFreeSpaceExA could not be found in dynamic
KERNEL32.dll Error code: 127
This issue was resolved in a later version.
