Lol I was surprised to see the system stats on netcraft today (systems with longest uptime) 1mobilewebwin2.necsoft.com138414271428BSD/OSMicrosoft-IIS/5.02www.windows-sc.necsoft.com138214281428BSD/OSMicrosoft-IIS/5.03ns1.necsoft.com138114271428BSD/OSunknown4dwh-sc.necsoft.com138014271428BSD/OSMicrosoft-IIS/6.05www.asp.necsoft.com137914261427BSD/OSunknown It says that 3 of the 5 systems with the longest uptime are running IIS 5.0 or 6.0 on BSD/OSD?!? Isn't that quite impossible? http://uptime.netcraft.com/up/today/top.avg.html
They might be using BSD as a firewall/proxy, infront of the windows server (IIS). It would show up the same way on my personal web server when I had a BSD firewall setup...
