Hi, I taken the replication form the windows 2008 DC. And it is successful by getting some issues faced on joing the samba DC. After i used the ps aux command to see the output of the samba instance. suddenly it shows 90% of CPU consumption. During the sync rep from the windows DC, i can not connect with the winbind client. Then i remove the sync with windows DC rep, then the sync is not happening with the windows DC and the CPU percentage also come down. Now I can easily join the winbind clients. So it ensures that if it is high CPU percentage then the winbind is not able to connect with the samba DC. How i can control the CPU consumption and sync rep from windows DC. -- with regards Ashok Kumar J
