Looking for a little help here.
I have a Windows 2003 DNS Server set up on our network. Lately computers on our LAN have been, at times, unable to resolve a certain sub domain for our website whereas other times the request is resolved just fine. During these periods of "downtime" all other network activity (i.e web sites, internal resolutions, network shares, etc.) remains normal. I can tell it is a problem with our DNS server because the resolution always works from outside our network.
I'm hoping someone out there has experienced something similar or could at least offer me place to start troubleshooting. Thanks!
