I've been troubleshooting random, intermittent "page not found" errors on a
couple of our intranet sites. Domain with about 30 users, single subnet,
nothing unusual with our DNS config to my knowledge. The problem will
affect an individual user even while other users continue to use the site
without trouble. After a short while (10 mins? 30 mins?) the problem
clears up on its own. After discovering that a reboot fixes the problem, I
dug further, and here's what's happening:
While the problem is occurring, I can ping the target intranet site by IP.
I can resolve the site's dns name using nslookup. But I *can't* ping the
site by DNS name. "Ping request could not find host funtimes. Please check
the name and try again." Ipconfig /flushdns doesn't fix it. However,
ipconfig release & renew (actually just "repair" from the gui) *does* fix
the problem.
In watching the messages that flash by during the repair operation, I'm very
familiar with everything that's taking place except the messages having to
do with NetBT. The Clearing NetBT and Refreshing NetBT messages, iiuc, have
to do with NetBIOS over TCP/IP, but it's not clear to me what netbios name
resolution could have to do with pinging an intranet site by DNS name.
I'm stumped...any takers?
Thanks in advance,
BJ
