I have a single server domain running a SBS2003 server and a mix of about 10 WIN7 & XPpro PC's. Experiencing intermittent name resolution issues on all computers. While issue is happening I can ping IP's on the Internet but neither Explorer or command prompt will resolve a name. Have looked at server DNS and ensured good forwarders are set and have tried other known good forwarders as well.
Last time issue was happening tried working directly from server. Explorer could not resolve a name but I could ping www.google.com
, resolve IP and get a reply. Restarting DNS server service clears problem but only for hours.
Next time issue happens plan to flush DNS server cache, local Server DNS cache, and a local PC DNS cache. Then try a tracert and/or pathping to www.google.com
and try to determine where resolution stops.
Troubleshooting ideas welcome as well as KB's for rebuilding/repairing DNS on a single server domain.
