good day everyone,
we have 2 servers with the role of global catalog servers, they both have FSMO roles distributed amongst each other, server 1 is a GC, DNS, DHCP AD server, server 2 has AD and is acting as a GC as well. server 2 has been around longer then server 1, server 1 replaced an old DC we had which has been d'commd. this is what happens:
when we restart server 2, everyone looses connection to the internet and are not able to log in. we find this strange being server 1 has DNS, AD and is a GC. we are wondering why users are not able to auhtenticate while server server 2 is being rebooted?
