A little description of the environment first:
Server : Linux SLES SP1
Zenworks: aupgrade to 10.1 with post-upgrade successfully applied
Workstation: XP SP2 and SP3

Problem: We are in the process of migrating the workstations from ZEN7 to ZEN10. All configuration have been migrated without problem. I first started doing my own machine to see what was missing.

Migration:
I deployed the ZCM agent without any problem. Zen7 gets uninstalled and the zen10 takes his place. REBOOT
At first the agent wasnt registered to the server...so I simply did it manually
zac reg -u user -p pass https://myserver.domain.com:443
No problem again, the device was imported and received the applications & policies.

When I get to the second and third computer, I deploy the agent, like the first one it doesnt register...so I send the ZAC command and it gives me this error message:
Unable to register with the server at: http://myserver:port
RegistrationManager - Network error connecting to server: Unable to connect
to the remote server


I get this error on both second and third machine. Also, here's the debug output...

**Just before you ask, I tried with the IP and DNS. I can Ping DNS and IP of the server. Im able to register some test workstations and laptops....

Here's the log file (DEBUG)
