I have a server running 4 scopes VLAN3,4,6,9. As of tuesday, the server stopped renewing IP address under DHCP. If I put in a static IP address there is no problem, but no computer can release and renew under DHCP.
Event logs: Show no trauma or anything
Reconcile: Database is consistent
Reboot: No change
Services: DHCP started and stopped
No rogue routers or other devices.
Any ideas?
