We are facing a very weird issue with one of our DHCP server. The DHCP server is Windows 2008 Server. We have configured the scope. The clients are getting the IP address from DHCP server, and the lease is showing in the DHCP console. But after some time
the Lease information gets removed from DHCP Server Console. The client still keeps that IP and we can ping that PC. Lease information keeps coming and going from Console. If I check the DHCP log file I can see that DHCP server is assigning same IP to same
host again and again.
Sometime the same IP gets assigned to other PC and IP conflict occurs. We have tried changing the DHCP server but same issue.
