Hi Folks I know this is a little off whack for this forum, but I've not had much success on the 2000 list and hope you will indulge me.
I have 5 win 2000 servers in a datacentre. They are not in a domain. These servers call urls for external services, payment mechanisms and the like. They have the same DNS servers configured and the same IP Filtering. Now, for some reason on a random server certain domains names fail! They cannot be reached on a web browser nor can ping resolve the DNS - but other domains work fine - this is really odd bit though, nslookup has no problem and ping within nslookup works, to the nslookup tool all is well. Even going through the server list of the primary and secondary servers they work fine. In this situation the other 4 servers in the datacentre are also fine and ping the troubled domain with no problem. After appros 2 hours - looks like a timeout period - all is well again with no intervention from me. IPCONFIG /FLUSHDNS has no effect and IPCONFIG /DISPLAYDNS appears correct. This behaviour has occurred on each server but as of yet only one at a time. Last time it occurred IIS had been restarted so my thinking is that it re-cached the domain names and somehow got a duff one, why I do not know. Does anybody know why a ping resolution would fail and nslookup succeed? Does windows 2000 have a cache other than IPCONFIG /FLUSHDNS that is flushable. The only linking factor is the firewall, but that does nothing at a domain level. This has me pulling my hair out so any help will be appreciated. Thanks Alister. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
