I have a Samba and LDAP network setup. I needed to change the IP address of my Samba server. I changed the address from 10.0.0.51 to 10.0.0.50. I just edited the /etc/sysconfig/network-scripts/ifcfg_eth0. Now I cannot get any XP machines to join the domain. The machine name is already in the database. I made sure my /etc/hosts file did not correspond to the old ip. I can still logon with machines that had been added previously, just not add a new one. If I change the IP back to 10.0.0.51, then everything functions correctly. Anything else that I should look for?
