invalid network adres

Hi,

I have a windows server 2012 and a windows 8 client. Both are DHCP clients of a home router via wireless interface.

The address of the router is 192.168.1.1

The DHCP address of windows 8 is 192.168.1.108 mask 255.255.255.0

The DHCP address of 2012 is 192.168.1.109 mask 255.255.255.0

I can ping from the client to the server.

I can login in the domain on de 2012 DC with a domain user from the windows 8 client but when I change the password of the user on the client I get the message "invalid network address".
