non-existent domain

[Junxiu Liu]

Hi,

One of our caching-only DNSs stops working after reboot. When I tried
nslookup command,  error messages showed up as follows:

Can't find server name for address "DNS-IP-ADDRESS" : non-existent
domain.
DNS Lookup (GetHostInfoByAddr) Unsuccesssful
DNS Lookup (GetHostInfoBy) Successsful

So, I edited the file /etc/resolv.conf on a client machine, changing the
nameserver's IP address into the nameserver's hostname. When I called
nslookup again, no error came out. I think that such modification on
/etc/resolv.conf is not recommended.

Any comment will be much appreciated.
