Hello,

After  installing  9  new desktops with DHCP I  changed  the  network
config  to  static  IP and restart the network.  But they  are  still
requesting DHCP adresse.  The dhcp server gives them a dynamic IP and
then  there  are  no  free  lease  (we   have  only  5  for  guests).

It  is  the first time I see that and I really dont  understand  what
happened.

There  is  no  NetworkManager no avahi-daemon no nscd  and  no  clone
interface.

So I have one static IP and one dhcp IP on eth0 I can ping:

seraphine.lmd.jussieu.fr  (134.157.47.113) at 00:25:64:9E:CE:A2 [ether] on eth0
shaughnessy.lmd.jussieu.fr (134.157.47.30) at 00:25:64:9E:CE:A2 [ether] on eth0

I  removed  dhclient but I still see the request on the logs  of  the
dhcpd server.

Feb  6 15:51:12 moore dhcpd: DHCPREQUEST for 134.157.47.30 from 00:25:64:9e:ce:a2 via eth0
Feb  6 15:51:12 moore dhcpd: DHCPACK on 134.157.47.30 to 00:25:64:9e:ce:a2 via eth0

Theses  machines  (Dell  optiplex 760) were installed with  the  same
kickstart file.

Only 7 show this behaviour the other 2 don't.

Note I have not had this problem with 5.2.
