Windows 2008 R2 nslookup does not resolve ../etc/hosts but ping does

I have a strange problem my server has 2 network one for production the one connect to AD, DNS and other for backup, we use our standard name server-bck,  for the server-bck I put only  in the c:\windows\system32\drivers\etc\hosts file not in the DNS server

Strange thing if I ping server-bck it can resolve to the IP, but if  I do the nslookup server-bck, it won't resolve anything, but nslookup will resolve anything on our DNS server.

Anyone know the answer?

Thank you.

Hi Iwan,

Local host files are just that - local - whereas the nslookup that you're performing looks for nameservers in yor network to resolve dns queries. Without a valid dns entry, server-bck will not resolve despite replying to the ping requests.


Thanks,

Chris

Hey Chris thanks for the very quick response?

Does Windows nslookup work like UNIX nslookup that can be configured to see files an DNS server?

Hi Iwan,

No problem. I don't have much experience with UNIX based systems, but I don't believe it's configurable in the same way. From a quick search it looks like UNIX systems use a file called resolv.conf, which can be edited and presumably therefore configured to see items outside of DNS.

Windows on the other hand isn't configurable in the same way, although it is possible to manually add DNS entries to your DNS server.


Hope this helps,

Chris
