Issues with DNS Entries

Posted on 2011-05-01

I recently took out one of the machine from our network but when I open up the command prompt and ping them I get a reply back.
So i thought it might be an issue with the DNS entry so logged into the DC and deleted the Host record for that computer name.

The computer name is : comp001
Ip adress:

but when I perform a PING -a I get a reponse from another machine which is on the N/W.
I am sure that comp001 is out of the N/w because I have it at my desk shutdown and un-plugged but I can still RDP to it using its name but when I log on to the PC and check the actual computer name its of a different machine.
Can anyone tell me what's going on?
after i deleted the Host record for Comp001 I did a ipconfig/flushdns and register but that did not help.

How is it possible that I can still ping the machine name when its no longer on the N/W?

    Have you by any chance got it listed in your HOSTS file (in C:\Windows\system32\drivers\etc), or do you have more than one DNS server available (in which case check that server too).

    Try using nslookup also to see what DNS server is providing the response.

    Hi Roy --> You know that;s the first thing i checked coz I have this habit of editing the hosts file all the time but luckily there were no entries in that its all clear!
    Also I forgot to mention that we also use WINS servers, so what I did that I seached for thr computer name "COMP001" in our wins database and I found entries so I deleted those entries also.

    After I deleted it from WINS it looks to be no longer pinging!!

    Excellent. One other thing I WAS going to suggest was stop stop and restart the DNS Server service on the server...

    It was a WINS issue so when we remove  the object from WINS everthing was good
