DNS Fails to respond properly
Posted on 2004-10-06
I'm working with a client right now that has an odd problem. They are running a server with Windows 2000 server, SP4. For some reason, the server will stop resolving DNS properly, until I do anything to the DNS entries. Then everything will work fine for about 10-15 minutes, then it will stop again.
For example... there are three servers in the DNS settings. All are good addresses, all are DNS servers that are online and functional. When the server stops resolving DNS properly (as in, addresses outside the LAN cannot be resolved), all I have to do is go into the DNS settings and change the order of the servers, and boom, eveything works well again.
For a little while. Then it will stop, I rearrange the entries, and all is well again. I've even tried setting it up so there's only one DNS server. Same thing happens - resolution stops, I modify the entry to a different server, and everything works again for a short time.
Any thoughts? This has apparently been going on for quite some time, but their last contractor was either unable to find the problem, or didn't look deep enough to try to fix it.
Many thanks in advance,
