I hope there is someone that can help. I need to create a remote account on windows 7 Ultimate x86 and be able to connect to it remotely without logging the current user off.
Sure,
1) Download this, and patch: http://deepxw.blogspot.com/2009/04/universal-termsrvdll-patch.html (note that it's not technically legal to do, if you're concerned about that. If you legally want to allow multiple sessions, you must purchase Windows Server / TS license)
2) Add a new user account for the person who will be logging in through Terminal Services (Remote Desktop/RDP):
As an administrator, open the command prompt console, and type the following:
NET USER <username> <password> /add
And if you want the account to have administrator rights:
NET LOCALGROUP Administrators <username> /add
(Just replace <username> and <password> with your chosen username and password respectively)
