The problem occurs when the computer is restarted or turned on, causing loss of IP. It is reviewed and there is an IP that starts with "169. ..." or that is duplicated.
This problem occurs with both static and dynamic IP addresses (dhcp).
It is solved by disabling and re-enabling the network or reconnecting the network cable.
The problem occurs in different computers, especially in win7.
The DHCP server is a Cisco 3650x
We await your help, thanks.
