Client on OS X, Browsers ALL fail DNS Lookup off net Hosts, SMTP+shell OK

[efbatey at gmail.com (Everett F Batey II Gi)]

Newly evolved problems 
   (network has been good for years, no recent known upgrades, config changes):
   Clients on MAC OS X, 
   Browsers ALL (FFox, Opera, Safari, Chrome) fail DNS Lookups for non-local web servers,
   BUT:   SMTP mail, POP, IMAP and shell commands (ping, trace route) fully OK
   AND:  www.google.com and a very few .orgs resolve on web browsers.
   Connected via TWBC:  RCWE, 13820 Sunrise Valley Drive, Herndon, Allocations for this OrgID serve Road Runner commercial customers out of the Honolulu, HI, Kansas City, KS, Orange, CA and San Diego, CA RDCs.  (Probably Orange Co, CA) 
   No, MAC has no nsswitch.conf .. to there.
      MAC HACKED (  )    DNS HACKED (  )  ISP FAILED fwdg DNS (  )
       OTHER IDEA,  START POINT ____    Thnx
