Trying to do an update, when I get the message "Synchronizing with ZENworks" it just sits there for ages and then times out.

On aborting, I then get the message "Service added to Yast but could not be synchronized with ZENworks", not surprisingly.

Then I get "Error - Cannot write settings to ZMD".

Please, what is going on, or rather not going on, and anyway what is ZENworks??
