Vitalix Posted June 29, 2005 Share Posted June 29, 2005 Good morning guys and gals,We have a strange issue here. We have a primary domain called abc.inc which is AD integrated, and all DNS requests within the domain are handled normally.We created a new DNS domain (we'll call it new.inc) which has names of kiosks we have out in the field with a different subnet and are not on our AD domain. It seems like a couple weeks ago, out of nowhere, we could not resolve those new.inc names in DNS without hitting ipconfig /renew in DOS!All DNS and DHCP entries look OK. Anyone have any ideas why this can happen. This can happen a couple times a day, where I would have to hit ipconfig /renew just to browse non-domain DNS entries!Please help!Thanks in advance as always!Vitaly Link to comment Share on other sites More sharing options...
FAT64 Posted June 29, 2005 Share Posted June 29, 2005 Have you enabled Dynamic Updates? Link to comment Share on other sites More sharing options...
Vitalix Posted June 29, 2005 Author Share Posted June 29, 2005 Have you enabled Dynamic Updates?<{POST_SNAPBACK}>Yes, for all the domains. What's odd is that I can nslookup anyone at any time, but cannot ping them or browse until I do an ipconfig /renew! Link to comment Share on other sites More sharing options...
FAT64 Posted June 30, 2005 Share Posted June 30, 2005 OK, have you tried ...ipconfig /flushdnsand then ...ipconfig /registerdns Link to comment Share on other sites More sharing options...
Vitalix Posted June 30, 2005 Author Share Posted June 30, 2005 OK, have you tried ...ipconfig /flushdnsand then ...ipconfig /registerdns<{POST_SNAPBACK}>That seems to have worked, at least initially. Will try to ping again in a couple hours and see if it sticks!Any idea why DNS/DHCP would do this for no reason out of the blue? Link to comment Share on other sites More sharing options...
FAT64 Posted June 30, 2005 Share Posted June 30, 2005 It's probably a Microsoft "feature"! Link to comment Share on other sites More sharing options...
Vitalix Posted June 30, 2005 Author Share Posted June 30, 2005 It's probably a Microsoft "feature"! <{POST_SNAPBACK}>Dam! No dice. Looks like same issue. Tried restarting DNS server and DHCP service. Same issue,Looks like definitely DHCP related, since an ipconfig /renew seems to reset everything. What's really aggravating is that nslookup works just fine, but then I can't ping anything right before or after the nslookup with the /renew!Please help!

FAT64 Posted June 30, 2005 Share Posted June 30, 2005 Do you have "Register this connection's addresses in DNS" ticked in the Advanced options of the TCP/IP properties on the clients? Link to comment Share on other sites More sharing options...

FAT64 Posted July 1, 2005 Share Posted July 1, 2005 When you "ping" do you ping using the computer name or IP address?What message do you get? Does it "time out"? Link to comment Share on other sites More sharing options...
Vitalix Posted July 5, 2005 Author Share Posted July 5, 2005 When you "ping" do you ping using the computer name or IP address?What message do you get? Does it "time out"?<{POST_SNAPBACK}>When I ping the IP address, it replies no problems. When I ping by name, "ping request could not find computername."A simple ipconfig /renew makes the workstation see DNS again. Link to comment Share on other sites More sharing options...
FAT64 Posted July 5, 2005 Share Posted July 5, 2005 If the ping by computername fails, then your DNS server is not behaving. Is there any way you could remove DNS and reinstall? Link to comment Share on other sites More sharing options...
FAT64 Posted July 5, 2005 Share Posted July 5, 2005 Do you have the same settings in the "ipconfig" screen before and after a renew? Link to comment Share on other sites More sharing options...

Is there any way you could remove DNS and reinstall?<{POST_SNAPBACK}>Can that be done with Active Directory running?The fact that I have to keep hitting /renew, is this a DHCP issue?DHCP is not set to expire for 7 days, yet for some reason it seems like it's not the case. The only DNS that works after several hours is the AD DNS, not extraneous DNS domains on the DNS server. Link to comment Share on other sites More sharing options...
