Unfortunately I had a SQL Database error and had to uninstall UrBackup server and reinstall a fresh copy of UrBackup server 2.0.32 and resetup all the settings. Will it just take time for the clients to discover the new UrBackup server? I am not seeing the clients being discovered by the server.
Have you tried downloading the client from the server web interface?
