Able to ping old computer no longer on network

-One of the Attorney's in my office went out of state (off the local network) for a few days.
-He changed his computer's name while off the local network.
-Now that he's back in the office I am still able to ping his old computer name.
-His old computer name's IP is the same as another computer in the office.

Why would it be doing this?  I can still ping his old computer name somehow and it is sharing the same IP as another computer in the office.  How do I make it so that it doesn't show his old computer name on the network anymore.

Go to Active Directory users and computers and go look under computer accounts and see if the old account name is possible listed there if it is just delete it.



What type of network is it NT Domain Controller or AD?.

Well, the DNS entry for his old computer name could still be there, you can manually delete it (if you have DNS servers)

Otherwise it may be in your cache....go to a command prompt and try these

nbtstat -RR

ipconfig /flushdns

We use AD.  I've already tried "ipconfig /flushdns, ipconfig /registerdns" and "nbtstat -rr".

If you can still ping the computer name, like I said in the first comment, you have to go to the DNS server, or Manage the DNS servers, and look if an entry still exists for the OLD computer name....if it does, then manually delete it
