Greetings: I have succesfully set up samba/ldap/nss_ldap/pam_ldap. I am replacing an existing samba 3 pdc with it. My problem is that if the IP of the new pdc is different than the old one, even if the old one is off, the network doesn't see it, or perhaps the new pdc doesn't register properly with wins. I use nbstat -RR to clear the WINS cache on a workstation, but a few minutes later the old pdc with the improper IP is back. What else should I look for to troubleshoot this? I read the "Making happy users chapter" of the online samba books, as well as the migration docs, which say the IPs can be different. Thanks.
