Server is running Microsoft Small Business Server 2003 & I converted from a single NIC to multiple NICs since the initial setup. I have DHCP running & scoped (green arrow), but nothing downstream is seeing the server (or vice versa). Problem is very similar to what was experienced by
but I'm hoping to avoid the reinstall.
Current architecture is...
Cayman DSL modem - gateway IP (18.104.22.168, subnet 255.255.255.248) (fictitious address for demo)
(5 static addresses available - DHCP off in Cayman)
Static address range 22.214.171.124-106
Single Cable from Cayman to 5 port switch with cables from there to NIC card A & NIC card B
126.96.36.199 assigned in Windows to NIC card A
188.8.131.52 assigned in Windows to NIC card B
NIC card C assigned static address of 10.0.100.0 - subnet 255.0.0.0
DHCP enabled for domain.local
Cable from NIC card C goes to 8 port switch with network printer and several machines plugged into it.
None of them can ping the server or obtain an IP address from it. I verified the switch worked by pinging the printer's 169.x.x.x APIPA address.
