I have a laptop and a desktop computer. I am trying to share a folder between them. The laptop is a business laptop and is registered on my business domain. My home computer is on its own. I was able once to login to the computer from my laptop and view the folder. I was prompted to enter the username and password, so i entered Administrator and then the password for that computer. Then i restarted my laptop and desktop and tried to access the desktop again with my laptop. Again i was prompted to enter the username and password. I entered Administrator and then the password. This time it didn't work. I tried every other username possible and nothing worked. I think its some security issue.
