Hi Erick, Thanks for the reply. It seems I have not done all my homework yet.
We used to use Solr 3.6.2 on the old environment (we're using it in conjunction with Drupal). When I got connectivity problems on the new server, I decided to rather implement the latest version of Solr (5.5.0). I read the Quick Start documentation and expected it to work first time, but not so (as per my previous email). I will read up a bit on ZooKeeper (never heard of it before - What is it?). Is there a good place to read up on getting started with ZooKeeper and the latest versions of Solr (apart from what you have replied, of course)?
