error fetching interface information

when i start up my linux(redhat 6.1) computer, the NIC is brought up well:
Bringup interface eth0 [OK]
but after i login, ifconfig can only show:
lo Link encap: Local Loopback
inet addr: Mask:
... ...
without any eth0 information.

i config the NIC by hand, ifconfig eth0 netmask, ok. eth0 works well, i can ping other computer with eth0. while if down it, error shows:
down: error fetching interface information: Device not found
it can not be down at all.

what's wrong with it, any suggestiong?

try to plumb it first.
#ifconfig eth0 plumb

Then try it again:
#ifconfig eth0 netmask up
then down it and see if you get errors.
