detection WINDOWS NT4 on network detection WINDOWS NT4 on network dlpar (TechnicalUser) (OP) 7 Sep 09 10:13 Hello, Do you know how to detect if there are still WINDOWS NT4 on a network composed of numerous windows boxes? RE: detection WINDOWS NT4 on network itsp1965 (IS/IT--Management) 8 Sep 09 10:55 Although a port scanning tool like NMAP, Superscan or others can tell you if a particular host is a Windows host, I don't know if they get that granular in identifying the version. I would suspect that only Windows NT 4 would be one that doesn't support SMB over TCP on port 445 which would separate it from Win2K and above versions of Windows. Also bare in mind that these tools may not work if firewalls are in place as they will most likely filter protocol scanning ICMP packets RE: detection WINDOWS NT4 on network cmeagan656 (TechnicalUser) 8 Sep 09 16:00 Are you on a domain and do you have a Windows Server 2003? If so, try Server Manager. It's a free Microsoft download. II haven't used it for at least 2 years but if memory serves me correctly it shows NT 4.0 boxes as Windows NT 4.0, Windows 2000 boxes as Windows 5.0, and Windows XP boxes as Windows 5.1.
