Error: When I run zwsreg.exe on a worktation, respond by "Could not locate the target container." In C1, the workstation's information no long update.

Troubleshooting: Found the Server Certificates in some LDap servers was expired, then I recreated a new certificates used "namconfig -k" for each Linux server, and also used iManager of those servers to created a new Server Certificates. Now, in both of C1 and Imanager, The certificates show valid, but the "Auto Workstation Import/Removal" is still not back work. "ZENworks Auto Workstation Import/Removal Component novell-zdm-awsi is Running" show on the server's terminal window too.

Any idea?? Thanks for your respond
