I have had both of these issues and I figured it would be easier to just put them both together.

1.) When I tried to login with the laptop I was working on, I was presented with two login screens, the normal Novell Client login, and then a second one for ZCM, when I tried to login I was presented with the following error," Unable to log into the network because cached login information is not available", I cancel past the screen but I would like to know what this error is relating to?

2.) When I tried to register the workstation, with the following, "zac reg http://ipaddress " I get the following error, " server code -34 server message invalid device authentication information", has anyone seen this message?
