  • Hi,

    Thanks for your question. Please try the following suggestion:

    1. Make sure that the computer’s PTR record exists in the Reverse Lookup Zones of local DNS server and ensure it correct. If its system has been reinstalled or quit domain, the old record would remain on DNS server for a while, and DNS would response the old probably. Please check the record.
    1. Type the command “ipconfig /flushdns” on the DNS server to clear up the aged records. Then restart DNS server or Reload the DNS zone.
    1. When you use ping -a 192.168.40.92, it returned internal name or external name? short name or full name?

           Please type the command “nslookup -d2 -type=ptr 192.168.40.92” at the CMD.exe on the computer you ping to monitor the name query process and drop me the result here.

    1. Please remove appended DNS suffix of the computer you ping and check “Append primary and connection specific DNS suffixes” on Advanced TCP/IP settings of IPv4 Properties as the following figure.  

                      

    1. Set scavenging and aging time on the DNS server. Please refer to the following link and figures:

    https://social.technet.microsoft.com/wiki/contents/articles/21724.how-dns-aging-and-scavenging-works.aspx

                         

                    

    Hope the information above helpful.

    I really appreciate your effort. If you have any questions or concerns, don’t hesitate to let me know.

    Wish you have a nice day!

    Best regards,

    Michael
