Hi friends
i have encountered an strange case.
in my test lab, i have deployed a windows 2008 R2 domain controller & i joined a win 2008 R2 to my test domain.
after first restart, i logged in as local administrator & removed the ip address of DNS server (which is the same as DC) & then log off. now i can log on by any domain user credentials & it's unusual! isn't it ? (note that no domain client has logged on yet , so they are not logged on from cache. its their first log on)
since DNS server is not Set on NIC, where from detects the domain controller?
where are these information saved in domain joined computer? where from can i remove this info so that when DNS server is not set on NIC, they be unable to log on to domain?
thanks in advanced
