|Message:||The IP address lease %1 for the Network Card with network address %2 has been
denied by the DHCP server %3 (The DHCP Server sent a DHCPNACK message).
The DHCP Server service did not extend the lease on your computer’s IP address, so your computer temporarily lost its connection with the network.
This could be caused by a scope change. For example, when a roaming laptop moves from one network to another, its IP address lease might need renewal. When the DHCP Client service tries to renew the address, that request might go to a different server that will not extend the lease either because it does not know about this address lease or because it has already issued the address lease to another client.
This also happens when two DHCP servers are configured to give out addresses in the same IP address range.
No user action is required. The DHCP Client service will continue trying to obtain a working IP address until it succeeds, and DHCP establishes the network connection on its own.
