So!
I am able to see OMSA 6.0.3 on my ESXi server via the 6.0.3 Server Administrator on my laptop. Whew! Now, I would like to get my ESXi server to show up properly in IT Assistant ( 8.3.0 if it makes a difference ). From my Googling and poking around, CIM is the only way to do this. But CIM expects "domain\username". What is the "domain" for my ESXi? I tried the hostname and FQDN to no avail.
Bump for the morning crew...
I havent' dealt with OpenManage / IT Assistant myself, but it looks like it may be an issue - http://blog.bruteforcetech.com/.
