DNS issue or.....?

[Jawloms]

I have a strange problem. If I ping some computer names, the correct IP address for that device is resolved. If I then ping that IP address with a -a switch it resolves to a different computer name. One of them (that I know of) is resolving to a computer name which I deleted from AD a couple of weeks ago, and I can't see it in DHCP or DNS. What's going on? This happens from any client/server on my network. ipconfig /flushdns makes no difference. All clients get their DNS servers through DHCP and the only two they get are my two DCs which are DNS servers too. The DNS servers listed on a client under ipconfig /all are IPv4, no IPv6 ones are there.

 

Any clues? It's causing me an issue because when I try to push SIMS on to a client using SOLUS 3 it gets all confused and refuses to work.

 

Thank you

Sounds like stale data in DNS -> Reverse Lookup Zones, have you checked in here? Guessing scavenging isn't turned on or it's not had long enough to clear out the stale records.

Yup, reverse was full of old entries. Thank you
