SBS2008 network. The SBS box is in charge on the LAN, running DHCP & DNS.
The network is 10.0.100.x
PC1 has dynamic IP 10.0.100.11
PC2 has dynamic IP 10.0.100.15
All PCs and servers on the network resolve PC1 & PC2 to 10.0.100.11
There are no hosts or lmhosts entries
I've stopped DNS & DHCP on the SBS box, cleared the DNS resolver cache, released IPs on the clients, restarted DHCP & DNS and reconnected the clients. Same result.
Please unbaffle me.
