Solution
1.
Disable the client's network adapter or disconnect the client's network cable. Ping the IP address
of the client from another host to check whether there is a host using the same IP address.
2.
If a ping response is received, the IP address has been manually configured on a host. Execute the
dhcp server forbidden-ip command on the DHCP server to exclude the IP address from dynamic
allocation.
3.
Enable the network adapter or connect the network cable. Release the IP address and obtain
another one on the client. For example, to release the IP address and obtain another one on a
Windows XP DHCP client:
a.
Run cmd to enter DOS window.
b.
Enter ipconfig/release to relinquish the IP address and then ipconfig/renew to obtain another
IP address.
c.
Enter ipconfig/all to verify other information such as mask, default gateway, DNS, and lease.
