Server version: Windows server 2008 R2 Ent.
Structure of DHCP scopes: Two DHCP server 50% to 50% all allocation for per scopes.
Question: Sometimes the DHCP serverallocate the IP address at the same time to the a strange MAC address per IP address, the type is "DHCP/BOOT", it cause DHCP scopes out of space at some time point. We need clear up them manually.
I found strange MAC address in HEX is the IP address which the server allocated.
Someone meet the issues before, any solution for this ?
Thanks !
