DNS server addresses

Hi ,
I have question.  All user's PCs are getting IP addresses from DHCP (in windows 2003 environment). From user's pc, i use ipconfig /all and it shows 4 DNS server IP in order.  Two of them are old external DNS server Ip addresses.  I already changed these two old DNS Ip addresses with the new ip addresses in our DNS server (in tcp/ip setting tabs) and also in DHCP server.  However when I use ipconfig /all from user pc, it still shows two old dns addresses.  I also did ipconfig /flushdns but still show the same.  Does anybody know why?

Try an ipconfig /release
then
ipconfig /renew

this will relase the lease and then renew should clear up

It is possible the client's TCP/IP settings are statically configured for DNS even though they are using DHCP for the IP address. Double check the Internet protocol configuration of the affected clients to make sure both IP and DNS are set to "automatically obtain".

It may also help to delete the lease for that client in the DHCP management console and then release and renew the IP settings on the client-side using "ipconfig /release" and "ipconfig /renew".

Let me know if this helps.

You got it raptorjb007.  I just did update scope option in DHCP server (in DNS tab) and /release, /renew  before I saw your response.  It shows correctly now.  You still deserve the point,  Thanks
