I'd know is any way to change/rename NetWorker Server 9.0 's hostname?
I search for google, but there is old version documents.
btw. my customer's NetWorker Server and NMC is on the same host. (Windows 2012 R2)
I am pretty sure that this is possible. However, as there is still limited experience with NW 9 in the field, may I suggest you get Dell/EMC support involved.
