Say your dns server did not answer you in a timely fashion. Set a timer to wait longer in dig, so does your AD query roots or forward?
C:\Users\user>dig en.community.dell.com +time=30
; <<>> DiG 9.9.5-W1 <<>> en.community.dell.com +time=30
;; global options: +cmd
;; connection timed out; no servers could be reached
Extended the time and still nothing.
About the AD, here is the DNS section:
A quick translation:
Visor de sucesos = Event log (there no errors from this year or last even)
Zonas de busqueda directa = Forward lookup Zones
Zonas de busqueda inserva = Reverse lookup Zones
Where should I look for this information you are asking me?
Why don't you try looking up something else? Seems odd to me that it takes your dns 150ms to return the root servers? But he answered atleast -- so your timeout lookup up the dell records just means he did not find it from who he asks and so why it timed out asking him.. Did you try it again in a second or so? See if he got an answer by then? If not you need to move up the chain to see why your having a problem?
Im gonna do a google.com

so you can lookup who the authoritative dns is with a whois
user@linuxbox:~$ whois en.community.dell.com

with many different competing registrars. Go to http://www.internic.net

No match for "EN.COMMUNITY.DELL.COM".

Domain Name: DELL.COM
Registrar: SAFENAMES LTD

Name Server: NS4.US.DELL.COM
Name Server: NS5.US.DELL.COM
So can you query one of those directly for that dell record?
I pinged the first one ns1.us.dell.com and didn't reply or even resolve a IP...
C:\>dig @ns1.us.dell.com en.community.dell.com
Couldn't find anything either...
If you can not query the authoritative servers for that domain, its possible you have network connectivity issue to that netblock if your asking roots. Or the dns servers your forwarding too have an issue, like I said you need to move up the chain of dns your using to find where the problem is. If you directly ask where you forward and he can not look it up, but you can from directly from authoritative servers.. Then your forwarder has a problem - you should report it to them. Or use a different one, or use multiple forwarders.
Well, tomorrow the people who we pay for internet access (not our ISP) comes to better a deal; They aren't in the technical area but I will talk to them about this issue and see what they say...
