DHCP Service stops due to DHCP server on 2nd LAN

Site has two LANs & 1 printer. Both LANs run DHCP on SBS.

1st LAN is 192.168.1.x
2nd LAN is 10.0.0.x
2nd LAN owns the printer

SBS on 192.168.1.x has a 2nd NIC just for the printer on 10.0.0.x and shares the printer on  its LAN.

the 2nd NIC only has IP4 associated with it, no Client for MS Networks etc

All has been working fine. Today, the DHCP service on the SBS 2011 server on the 1st LAN stops immediately on starting with "The DHCP/BINL service has encountered another server on this network with IP Address, 10.0.0.88, belonging to the domain: ."

10.0.0.88 has been there all along providing DCHP on that LAN

How do I bind DHCP to the 192 NIC only to stop this occuring?

Short answer is you don't. SBS does not and has not ever supported 2 NICs. DHCP is also a broadcast protocol which means there is no way to specify that a machine should prefer one DHCP over another.

Realistically the way you want this set up is with a router or layer 3 switch that can bridge the two networks but will *not* relay DHCP traffic. That way each server only needs one NIC, is totally supported and things will work as designed and expected.

I've put in a router. Works well.

Can't agree about multiple NICs not being supported in SBS. How else would you install ISA?

Sorry. SBS 2003 did support multiple NICs. But the only supported topology was a WAN NIC and a LAN NIC. And ISA blocked DHCP on the WAN side, so you would not have seen the problem.

SBS 2008 and SBS 2011 do *not* support multiple NICs and do not support ISA on the SBS server.
