Novell ZENworks 10 Configuration Management with Support Pack 2 - 10.2 ZENworks Control Center - ZCC
Data will not remain saved when configuring TFTP replication settings in ZCC, located under Configuration/Preboot Services/TFTP Replication Settings. After browsing to a different web page within ZCC, the modified information for TFTP replication settings is back to the way it was before being modified.
This is fixed in version 10.3 - see KB 7005455

Bug 574058 has been created for issues seen with the tftp replication not working after the data in tftp replication is able to be saved.
