We have recreated a VMware environment on a single esx server from scratch. It has the same name, IP, etc. We are trying to reconnect the NBU server credentials to it, and it is failing. I triec bpclntcmd -clear_host_cache, but maybe I'm not on the right path... suggestions?
When you say you are trying to reconnect the NBU server credentials, what are you doing precisely? Are you removing and re-adding the backup host or adding vCenter / ESX credentials in the Virtual Machine servers section of Credentials?
