Does the DNS stop resolving everything, including internal resources, or is it just a problem with external resources?

There are no errors in the logs. Only warnings that the DNS server received an invalid packet from this or that IP address (some of those IP addresses are our BIND DNS servers) When it gets hosed, it even stops resolving names that are already in the cache. For example I could be sitting in NSLOOKUP, punching in edmunds.com, edmunds.com... no problem... all of a sudden, edmunds.com - request timed-out. Tried running NSLOOKUP -d2 and when it fails, the last thing it says is "SendRequest failed" Thanks for your help. I will see if I can run NetMon on it. -----Original Message----- From: Thomas Di Nardo [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 22, 2002 12:29 PM To: Exchange Discussions Subject: RE: Win2K DNS is PISSING ME OFF Have you run a netmon to see what the box is doing when it gets hosed? Are there any errors in the logs? Is it still resolving stuff in the cache, but not anything new? -----Original Message----- From: Andrey Fyodorov [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 22, 2002 12:24 PM To: Exchange Discussions Subject: RE: Win2K DNS is PISSING ME OFF No ISA. We have an access list with all the necessary ports open. The DNS servers have no problem communicating with root hints at the beginning. -----Original Message----- From: Thomas Di Nardo [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 22, 2002 12:17 PM To: Exchange Discussions Subject: RE: Win2K DNS is PISSING ME OFF Are you using ISA as a firewall? -----Original Message----- From: Andrey Fyodorov [mailto:[EMAIL PROTECTED]] Sent: Wednesday, May 22, 2002 12:16 PM To: Exchange Discussions Subject: Win2K DNS is PISSING ME OFF Hi all. I have two Win2K AD DNS servers. Recently they have been acting up: all of a sudden one of them stops using root hints and can't resolve a lot of good domain names (request timed-out). I restart the DNS server service and everything is OK again. Then 10-15 minutes later, it starts giving request timed-out. Both DNS servers experience this at different times. Has anyone here seen this? _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
