DNS

Hi,

I am running DNS services on a windows 2003 server.

I note that from the server if I type:
nslookup [an address I am using]
it times out.

If I go and clear the DNS cache and rerun
nslookup [an address I am using]
It works.

If I run nslookup [an address I am using] again
It no longer works

the nslookup will work ONCE after each time I clear the cache.

Any ideas?

can you tell  ur dns servre is connected to internet or not

how about your dns forwarders?
also please confirm how you are clearing cache
to clear the cache of dns server use dnscmd /clearcache.

shouldn't a server running dns ONLY use 127.0.0.1 as the dns server in the properties of the local area connection...?  Then the forward lookups should take over.  I shouldn't have to lest any other name servers in the dns of local properties - right?

Vinchenzo-the-SecondCommented:
Yes u right, it should use it self for its own lookups.  If u do have forwarders configured it will use this if it can't resolve.

Where are you doing the nslookup from?  Is it the DNS server or a client?  If its the client can you do the same from another client and the DNS server?

Vinchenzo-the-SecondCommented:
Do a dcdiag /v and post the errors? I am assuming the DNS server is AD integrated.
