RE: emulation of gethostbyaddr to resolve to NetBIOS name

Hi Paul,
Thank you for your clarification.
Actually gethostbyaddr() is not the culprit. As you can see from the KB
article, it is caused by the fact that some services, other than the
Workstation, that Register as Unique with the [00h] entry, will show up in
the NETBIOS Node Status Query response as well as the Machine Name and
unfortunately gethostbyaddr() cannot identify them and so it returns an
incorrect result.
As a possible workaround you had been aware of, I agree that you check the
name and remove "IS~" if it contains the characters.
Also I notice that the KB article only applies to Windows 2000 and earlier
Windows NT systems, could you please let me know if you also encountered
this issue on Windows XP/2003 systems? Anyway since NetBIOS is a very old
technology and the later Windows OS from Vista does not support it very
well. If possible, I recommend that you use DNS instead of NETBIOS.
Please feel free to let me know if you have any other questions or
concerns. Have a nice day!
Best regards,
Charles Wang
