I suspect you have the Earthlink DNS server manually configured in your
Ethernet settings.  When you go to work, you get new address, gateway, and
DNS information offered to you by the DHCP server; however, since yours is
manually configured it ignores the corporate DNS offering.

Check and see if a Earthlink DNS server is manually entered, and if so
remove it (would be named ns1.earthlink.net or similar). If that fixes the
problem at work, but breaks the ability to resolve names at home, then you
have to compromise somehow - you could create different locations for work
and home under Network Settings, or find a way to script adding and
removing the Earthlink DNS setting as you suggest.
