Re: DNS Forwarding Not Work



Hello mmsameed@xxxxxxxxx,

Did yuou configure the ISP's DNS on the NIC of the DNS server or in the DNS management console under the forwarders tab? Please post an unedited ipconfig /all from DNS server.

And just a remark, since windows 2000 there is no longer a PDC?BDC concept. All DOmain controllers are the same, the differences are the 5 FSMO roles used in the domain controllers. :-)

Best regards

I have simpe network like follow,
DSL Modem------> ISA Server ----> Switch--->PDC, BDC, Exchange,.....
All Servers Windows 2003 SP2,

In Our DNS Server (PDC) I have put Our ISP DNS Addresses as
Forwarders. But it is Not working. I mean i can not Browse internet
even i can not ping, nslookup any Internet site or IP.
I thought it was becaouse of ISA Firewall. then now i have Unstall the
ISA Server Services for time being to test the Forwarding. even not
working.
ISA Serve MAchine IP address

External Interafce : IP : Static, Default Gateway: DSL Modem IP, DNS :
Empty
Internal Interface: IP: Local Static IP : Default Gateway: Empty, DNS:
Local DNS Servers.
At the same time PDC's interface: IP: Static : Default Gateway: ISA
Server IP, DNS: Local DNS

When i try NSLookup from PDC to ISP DNS Server :

++++++++++++++++++++++++++++++++
C:\>nslookup ISP DNS Server or IP
Server: PDCname.Doamin.com
Address: 192.168.*.*
DNS request timed out.
timeout was 2 seconds.
*** Request to PDCname.Doamin.com timed-out
+++++++++++++++++++++++++++++++++++

Please be noted now there is no Firwall Server (ISA) not installed.

But Local NSLOOKUP is working fine.

Please Any one Help Me.
