network problem

Hi all,

we had a switch go bad and I replaced it with a managed switch which is set to non-managed just like the one being removed. When everything is re-connected I have 2 computers that will not talk to the DNS server and the DNS server will not talk to them. They all talk to the seconary DNS server without a problem. when i checked arp both show the dns server as invalid. Just in case the card was bad I removed and installed a new card to no avail. It seem the other 100 or so nodes are working fine. the dns is windows 2000 server and the other two are 2003 all are upto date

Thanks you both
what was the final solution?
The reason turned out to be many. 4 ports on the switch stopped passing packets, not sure if the host file was to blame but it was corrupted. Restore the host file replaced the switch and everything seem to go back to working.
cool...thanks for the clarification and the points!
Congrats on resolving.
