When I followed http://msdn.microsoft.com/en-us/library/fp179923%28v=office.15%29 ,section Create an isolated app domain on your development computer step 5, I should create a new managerAccount. But i get this massage every time when I try to create a new account:
I run it in this: Administrator: SharePoint 2013 management shell
My domain name for SharePoint is sp.com and when the create window appear I have entered this:
Account name: SP\spManager
(It's a local server for school, not on the internet)
My ultimate goal is to be able to use apps on SharePoint 2013.
