CentOS - Feb 2008 - CentOS 5 loses ip address (newbie question)

Reserved ip in 192.168.x.x range for CenOS 5 (Samba Server)

loses samba clients due to eth0 losing it's ip.

Sounds like your using DHCP. If you've reserved an IP then
set it statically on the server, as the dhcp client doesn't
appear to be able to renew the lease when it expires. You
can check the logs on the server to see if you can see why
it cannot renew the lease if you want as well.

What is your system setup?  Is it a LAN on the inside of a router?  Do
the systems exist inside and outside the router?

Need more information for this to be useful.

whack, 169.254.x.x is the 'auto-IP' range of self assigned IPs used if a
system can't reach the DHCP server.     I wasn't aware Linux did this, 
I've only seen it on MS Windows.
