Small network, subnet is 25-bit. Been fine for years, no recent changes, except as described below.
ServerA: 2003 R2 is a DHCP server (also DC, DNS, file/print etc). ServerA sits on hardware that will get flatted and 2008 R2 on it, so I stand up ServerB, again with 2003 R2. I make it a DHCP server, same scope and settings, authorize it, etc. Network was fine with this thing forever. I turn off DHCP of Server A so clients will start getting IP's from Server B and it works. Sometimes. Other times clients get an IP from 192.168.1.1. Some troubleshooting finds a Linksys router that I had totally forgot about using in just "switch" mode. WAN side unused, just the 5 port switch side utilizes (I don't even remember doing it, but I am the only guy who does IT stuff at this place, and in hindsight I can't believe this hadn't been only a temp solution). I bought a proper switch and solved the issue. My curiosity is why wasn't it an issue when ServerA was the DHCP server? The DHCP lease was set for 8 days on ServerA so it's not like in the last several months the PC's hadn't been doing DHCPDISCOVER several times...
