DNS Weirdness on my network

[REstabrook]

I recently had to rebuild a Terminal Server for use by our IT dept. I've made an entry in the foreward lookup zone for education-sales.net for the server TS3. The machine name is ESM190. From my workstation I can ping the name TS3 and it returns the correct IP address. When I ping the machine name ESM 190, it comes back with another machine address on the other subnet (we have 2 subnets on our network, as there are 2 locations), another employee's workstation. I should be able to ping ESM190 and TS3 and get the same IP address back. Has anyone ever seen this type of problem before?

did you flush the dns resolver cache?

What drew1701d says is worth a try.

Open a command prompt and type ipconfig /flushdns

If ipconfig /flushdns does not work, check your dns server for ip addresses that dont make sense. It is there where the machine you are pinging from is getting its info. Do you use dhcp?

 

[REstabrook]

I did C:\ipconfig /flushdns on the new server. shall I flushdns on the client that's resolving to ESM190?

 

[porkchopexpress]

Yes it if an incorrect address was picked up by the client then it will be in it's cache as well.

Thanks for all your help.. flushdns and then registerdns on both machines finally worked..
