Odd DNS problem , IP = ok , FQDN ! ok

[1DMF]

Hi,

I'm rather puzzled....

I am unable to ping / connect to our webserver via its FQDN which we have a VPN tunnel connection to.

If I ping the respective IP I get a reply, If I nslookup the FQDN I get the correct IP resolution.

I've checked the server event viewer DNS log, no errors reported.

everything seems fine, I've looked in the DNS Active Directory and there is the correct Host(A) record.

I can only get a response if the IP is used but not the FQDN

Any ideas as to what is going on?

Thanks,
1DMF

well it's happened a couple of times more, interestingly enough the 'sub-domain' computer NETBIOS name failed when pinging, yet the FQDN computername(netbios).internal-domain.local , replied when pinged.

all A (host) & PRT records are correctly configured for both subnet masks, even our server support MS gold partner guys are baffled!

So any help to point me the right direction really is appreciated!
