Samba Doesn't Work After Change Ip Address

I have a SLES 10 with SAMBA+LDAP. it was working very well until the change of IP address of the network card, now I can't create new windows workstations, the old IP address is 192.168.1.60 and the new one is 192.168.1.252; the log.nmbd file says this:

If any machines of the network "saw" the server at that address, it will continue to appear available.
Effectively your server is seeing an echo of itself still existing on the old IP address and is trying to synch to it.

Close the whole network down - bringing up the master server and then the clients should clear it.
