The AFS client service because of its poor design has a requirement that 
at the time it starts there must be at least one network adapter active 
on the machine with an assigned IP address.  The same poor design 
results in a requirement that all IP addresses which are active at the 
time the AFS Client Service starts must remain active or the AFS Client 
Service will die a premature death.

The use of the MS Loopback Adapter hack is meant to ensure that there is 
at least one adapter in the machine active with an IP address when the 
machine starts.  Secondly, by binding only to the loopback adapter the 
AFS client service will not die when other IP addresses are 
added/removed as may be the case due to PPP, DHCP, laptops being 
suspended/hibernated, network cables being disconnected, or wireless 
network connections dropping out. etc.
