Oneballbobby Posted September 30, 2008 Report Share Posted September 30, 2008 Yello..Everyday for about 30 minutes both ISA servers cannot connect to a hostname we have in DNS pointing to an external IP address. This in turn affects the clients trying to connect to the address. Although this will work if put through as an exception I'd like to get to the bottom of the problem.There is a correct answer if you query nslookup for the hostame on the servers, you can ping by IP address but when using ping or tracert to the hostname it does not recognise the target host. This only happens to the ISA servers and only for about half an hour each day. This affects no other traffic.Any ideas?OBB Quote Link to comment Share on other sites More sharing options...
Dencandy Posted October 1, 2008 Report Share Posted October 1, 2008 Sorry, I have no idea about this one. Anyone else? Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted October 1, 2008 Report Share Posted October 1, 2008 This affects no other traffic.When you say it affects no other traffic, do you mean you're able to resolve other domain names on the affected servers during the outages?

Oneballbobby Posted October 7, 2008 Author Report Share Posted October 7, 2008 Yes. Everything else is fine.=0/ Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted October 7, 2008 Report Share Posted October 7, 2008 Do you have any backups running that could affect service as DNS is backed up? Just a shot in the dark, but I can't think of anything else that could affect things so intermittently. Quote Link to comment Share on other sites More sharing options...
Oneballbobby Posted October 14, 2008 Author Report Share Posted October 14, 2008 None at the affected periods on either the DNS boxes or ISAs =o( Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted October 14, 2008 Report Share Posted October 14, 2008 Have you checked what services are running or stopped during the outages? Nothing in the event logs? Quote Link to comment Share on other sites More sharing options...
Oneballbobby Posted November 14, 2008 Author Report Share Posted November 14, 2008 Nothing amiss in the logs. All services fine.=0(Sorry about the delay, few things including a holiday meant I was no-where near the place.Because we've moved everyone over to bypass the proxy for the address, knowing when it's a problem isn't as obvious as before. Wouldn't worry about it, as long as the users are happy.Thanks for any help and suggestions!OBB Quote Link to comment Share on other sites More sharing options...
