Re: [K12OSN] Difference between K12lts versions and DHCP

Hello,
When I say "several dhcp servers running", I mean severa dhcp servers :
like a dhcp server in a router, a dhcpd server in a windows2000 server,
and the dhcp server.
I my school, there is in fact 2 dhcp servers running :
- one in a router
- one in a windows2000 server.
The sensitive point is that we don't have access to the router (support
given by a special enterprise), and so we're not sure that the ltsp's
dhcp will respond faster than the router.
In fact, one times it responds faster, one time not. Therefore, there is
no way to be shure that the LTSP client will boot properly :(
Btw, any advice concerning the version 3.01 of the K12lts regards to the
3.0 version ?
Regards,
Rémi.
