Folks with the automountd and backups.backupdb issue might find this snippet enlightening as well:
"In August 2006 EarthLink teamed up with Yahoo and Barefruit to redirect web browser users accessing nonexistent domains to a page containing sponsored search results, ads, and a Yahoo search form. The DNS protocol requires that a query for a nonexistent domain must return the "NXDOMAIN" error response. Instead of this response, EarthLink's DNS servers return several IP addresses for the HTTP servers that implement their redirection service. While such redirection might be helpful to users of some web browsers, it breaks the functionality of many other Internet applications, which assume that the DNS is implemented according to the standard specifications. Earthlink provide a non-patched DNS server address to enable users to have a standard NXD response, which they can use if they manually configure DNS in their systems.
Barefruit suggests a range of opt-out methods which some of their customer ISPs have applied."
From the Wikipedia entry for "Barefruit."
If you have this issue and don't use Earthlink, it might be helpful if you would add something here.
