Thanks all for your precious answers.
Since it can't be done, I have redo all the configuration and will add clients to the group.Now there are new problems occured.
I'm trying to push install packages to clients using remote push, I'm able to find my clients computer (using IP Address), but I'm not able to install it on remote computer.
Error: Login to www (192.168.5.21) failed. The client could not be installed on the remote computer.
Currently my SEP manager is installed on a machine with IP Address 192.168.6.18.
FYI, the clients that I want to push is being categorize in few different VLAN.
Based on the error above, what may cause the pushing installation package to be failed?
Is it because of the ports that is not open in firewall level or other issues?
Thanks for your reply.
