The other day I found 3 Rogue DHCP servers on our network. I thought that DHCP might be the issues but all the utilities I used could not find or see any DHCP servers except for our REAL DHCP servers for some reason. I had another network guy help me and we used WireShark to finally discover why I was having DHCP issues; we found 3 DHCP servers and I was hoping NetScan would have found them. I used NetScan several times to see if it could find them now that I knew where they were and what IP addresses they were at, but NetScan could not see them no matter how much I tweaked NetScan. With your wiki page link, I now understand that UPD is hard to scan for. Many Thanks -WS
Unfortunately it does not see the Rogue DHCP servers. I does see my real DHCP servers on Windows Server 2008 R2. The Rogue Servers (3 of them) were on a *IX box OS unknown, clever. -WS
