Workstation can't obtain IP

[James Keating]

hi all,

problem:

a win2k-sp3 client machine named joe in a remote building connected via T1
with Cisco routers works all year on ISC DHCP v3.0.3....

until monday. then, no amount of re-booting, ipconfig/release
and renew would obtain it a valid dynamic IP from the server.

i finally had to put in a static.

upon returning to the server, i found this in the dhcpd.leases file.

why the 2-minute lease? should be 3-days. any other way to force a renew?


lease 10.1.17.234 {
  starts 1 2007/05/07 15:31:47;
  ends 1 2007/05/07 15:33:47;
  binding state free;
  hardware ethernet 00:03:47:22:33:44;
  uid "\001\000\003Gc\330Z";
  client-hostname "joe";
}


here's my config:

#
# dhcp daemon
#
default-lease-time 259200;
max-lease-time 259300;
ddns-update-style none;
authoratative;
option subnet-mask 255.255.0.0;
option domain-name-servers 10.10.1.3;
option domain-name "mydomain.org";

subnet 10.10.0.0 netmask 255.255.0.0 {
    option broadcast-address 10.10.255.255;
    option routers 10.10.1.1;
    range 10.10.17.1 10.10.17.254;
    range 10.10.18.1 10.10.18.254;
}
subnet 10.1.0.0 netmask 255.255.0.0 {
    option broadcast-address 10.1.255.255;
    option routers 10.1.1.1;
    range 10.1.17.1 10.1.17.254;
    range 10.1.18.1 10.1.18.254;
}
