DNS resolution not working


D

David

Hi,

I have a problem with DNS resolution on a few desktops on our network. They
randomly stop being able to resolve DNS names within applications other then
nslookup.
This is what works and doesnt.
nslookup: works fine, resolves the host names.
ping: fails on resolving the host name, but will ping if ip address is
entered.
ie: fails on host name, works on ip.

Tried ipconfig /flushdns, doesnt fix the problem. But "ipconfig /release &
ipconfig /renew" fixes the problem for a while.

The DNS is working fine, as nslookup works and other computers on the
network are not affected. the problem appears to be location on the desktop,
but I am not sure what is causing it, driver problem? I have searched for
this and found a few other peopel else where have had a similar problem but
no solution was found.

Any help would be appriciated.

Thanks

Also noticed that these computers that fail to lookup, only fail on 1
specific server.

So 4 computers fail to look up a dns record for one specific server, on any
application other than nslookup. These lookups can be fqdn, and still fail.
The computers never do it at the same time and are random, when it happens
you can ping any other server, connect to any local of external website,
except for this one server, from the computer that is failing, all other
computers work fine.

To get the PC to start working correctly again requires you to do either
restart, or just do a release and renew with ipconfig.

DNS is working, as nslookup works from the affected pcs.
