I'm looking to setup the Zenworks agent on a SLED10 workstation. I currently
have the management software running on a server using SLES9.

When setting up the agent, I get the following message after entering the
Registration Key:

Failed to activate service https://server : [ ]

I've created registration keys etc on the server

On the firewall, I have the appropriate rules in place, though I have
switched off the firewall which returns the same error.

Any ideas?
