I started a command prompt and typed “ping myserver.mydomain.local”. Sure enough, I get back the message “Ping request could not find host myserver.mydomain.local. Please check the name and try again.”

An nslookup works fine, so I know the SBS server is there and is responding to DNS requests.

In fact, I can “ping myserver” without problems. But for some reason, pinging the fully-qualified internal name doesn’t work.

Sometimes, I can just type “ipconfig /flushdns” to clear this up. Today that didn’t work. However once I actually stopped and started the DNS cache, ping started working and so did email:

net stop DNScache
net start DNScache
