nonexistent workstation name still resolves in DNS RRS feed

  • Question

  • Hello, we have an AD domain and a few weeks ago I reimaged a workstation with the name of W01 using MDT and during reimaging I renamed it to W02. I can still ping the workstation using either W01 or W02 and it resolves to the same ip address. I have looked in DNS and there are no entries for W01.

    When I perform an nslookup for the A record of W01 I get a "can't find W01: Non-existent domain."

    Can anyone point me in the right direction as to why this is happening and how to resolve it?

    Thanks in advance.

    Jose

  • Hi,

    Did you ping with host name or FQDN?Host name may resolved by NetBIOS.Please try to disable the NetBIOS over TCP/IP and test again.

  • On the machine which can still ping either W01 or W02, look inside the \Windows\system32\drivers\etc\hosts file for a line with W01 and remove it.

  • Hi,

    As Todd mentioned,hosts file is one thing you need to check.

    In addition,please try to clear the cache on client and server.Client side:Run 'ipconfig /flushdns' in CMD.Server side:DNS manager=>Right click on your server=>clear cache.

  • Hi Todd, that was one of the first things I checked. I can ping from any host. Every host I have pinged from does not have the entry in the hosts file.

  • Hi Cartman, I also tried flushing the dns cache in both dns manager and cmd prompt, but can still ping W01.
