Today (after turning on the server from an extended power outage) some clients are not able to get IP addresses. Some clients work just fine. Win 7 and XP doesnt seem to matter.
I have tried flushing dns, renew, disabling APIPA and even assigned a static IP. Even with the static IP it acts as if it isn't on a network. You can't ping anything. I have also tried resetting the TCPIP stack.
The clients that work can ping the DNS and DHCP servers fine.
