I am a member of the local administrator's group on a Windows Server 2012 machine, but when I try to run IISReset from the command prompt I get:
Access denied, you must be an administrator of the remote computer to use this command. Either have your account added to the administrator local group of the remote computer or to the domain administrator global group.
I've disabled UAC on this machine, and I'm RDP'd in via remote Desktop Connection Manager, so I'm not sure why the machine thinks I'm not a local administrator.
