Domain Controller win't reach gateway or other networks after network failover

-

hello!

yesterday hade unwanted network failover in our "user network". after failover our physical domain controller won't reach outside current subnet. our virtual dc work should.

both domain controllers running dns , dhcp. problem seems tied ip-adress on failing dc, when change static ip-adress network communications seems fine. our network technicians thinks arp problem, tried clear arp cache without success.

any or tips very appreciated!

os: windows server 2012 r2

kind regards,

anthon

hi,

i dont´t think changing ip addresses of domain controllers idea.

supposing have 1 subnet , 1 domain 2 domain controllers... both dcs running dhcp? same configuration dhcp failover deployed? otherwise won´t networking perspective.
