i have an issue with DNS, where i have four servers in four seperate sites, they are all domain controllers, server1,server2,server3 and server4.
The dns name company.local is was initially setup on server1
two more servers where added over time (2and3), they both have the company.local setup in the dns console, but nslookup will only resolve to company.local when they are using server1 ip as the main dns source not their own ip
server four has its own dns name company2.local and resolves in nslookup using its own ip but still talks to AD on all the other boxes without error
server 1 is very slow to login, all other servers are ok
is this correct, if not what do i need to to to correct
