RE: [ActiveDir] DNS problem. Periodically have to clear the cache

[Ramon Linan]

Hi,
 
I have 4 DNS servers, they are all AD integrated.
 
2 of them are supposed to be for internal used only, and the other 2 for
the internet domain we have, unluckily they we never configured to be
split DNS.
 
Anyway, every none and then I have to clear the cache  for the internal
ones because they stop resolving for certain addresses.
 
Sometimes I also have to update server data files for the DNS server to
resolved certain names.
 
 
Any help on how to troubleshoot this?
 
Thanks
