Hi - On my CentOS 4 cobbler server i am having some odd dhcp issues.
There is only 1 dhcp server on the network and the cobbler box manages the dhcp. When i kick off the PXE install during the PXE phase things seem OK then when anaconda tried to get an IP sometimes things work out fine and other times it sits waiting for hostname/domainname. From the logs you can see that the mac requesting the IP is constant but the IP being offered is sometimes 'wrong'. In the 2 examples below nothing is changed the differing result is just achieved by trying another install, as i said its rather random.
Any thoughts?
thanks
