I have installed and configured the vMA 5.x. &nbsp;I have added and registered my vcenter server and two hosts (ESXi01, ESXi02). &nbsp;When i connect to the vMA using vi-admin and target the ESXi02 host i can run all my commands with out issues. &nbsp;However when I connect to the ESXi01 host and i try a command like resxtop i am prompted for user credentials, any credentials I try fails with &quot;Login failed, reason: vim.fault.NoPermission&quot; or &quot;Login failed, reason: vim.fault.InvalidLogin&quot;. &nbsp;Even though when I first connect using the vi-admin account I have tried supplying the vi-admin account, I've also tried using my windows credentials and that fails, also I've tried using the root account of the host and that fails as well. &nbsp;Both hosts look exactly the same so I don't know what is prompting credentials for one host and not the other. &nbsp;This is really bugging me so any help is greatly appreciated.

vSphere vMA

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
