Windows DNS weirdness: nslookup finds, ping doesn’t

The fact that this is possible boggles me:

—–
C:\>ping myhost
Ping request could not find host myhost. Please check the name and try again.

C:\>nslookup myhost
Server: dns.mydomain.loc
Address: 192.168.1.2

Name: myhost.mydomain.loc
Address: 192.168.1.4

C:\>ping myhost
Ping request could not find host myhost. Please check the name and try again.

C:\>ping myhost.mydomain.loc
Ping request could not find host myhost.mydomain.loc. Please check the name and try again.

What??

Despite multiple cache clearings, browsers can’t find it either (it’s an internal website). I am suspecting this is why. I am not sure how, after several /flushdns and /registerdns, if nslookup finds it right off, why can’t anything else..?
