Вчера случилась интересный глюк:

Windows 7 перестала получать айпишники от микротика.

Ругается на то, что этот ИП повтояющийся.

В этот момент Вин ХР, Линух нормально получают ИП и спокойно работают в сети.

В логах микротика следующее:

06:47:35 dhcp,info default deassigned 192.168.8.80 from F0:DE:F1:29:09:A4

06:47:45 dhcp,info default assigned 192.168.8.79 to F0:DE:F1:29:09:A4

06:47:46 dhcp,warning default client F0:DE:F1:29:09:A4 declines IP address 192.168.8.79

06:47:46 dhcp,info default deassigned 192.168.8.79 from F0:DE:F1:29:09:A4

06:47:56 dhcp,info default assigned 192.168.8.79 to F0:DE:F1:29:09:A4

06:47:57 dhcp,warning default client F0:DE:F1:29:09:A4 declines IP address 192.168.8.79

06:47:57 dhcp,info default deassigned 192.168.8.79 from F0:DE:F1:29:09:A4

06:48:07 dhcp,info default assigned 192.168.8.78 to F0:DE:F1:29:09:A4

06:48:08 dhcp,warning default client F0:DE:F1:29:09:A4 declines IP address 192.168.8.78

 

Мак - мак клиента с вин 7.

В логах таких строчек на каждый мак с 7й виндой.

В какую сторону копать?

DHCP настроено по привязке к маку или динамически раздается при каждом включении?

если динамически то попробуйте привязать к этому маку определенный ip
