You don't have the option "Users and Groups" on a Windows Home OS.
However, on any Windows Home (Windows Xp Home, Vista Home Windows 7 Home) it is not required to do this configuration step !
By default administrators and standard users have the permission to log-in via RDP to Windows Home systems with XP/VS Server installed.
If the problem still resists, first please check if you have installed XP/VS Server version 1.0.390 or higher. If not please update to this version(latest Release from XP/VS Server).
If the problem still persits upload a TSRP (Thinstuff Support Request Package)
on that computer where XP/VS Termial Server is installed and follow the instructions to upload the package.
We will then analyse it to find the problem.Tags: Add User, home system, operating systems, Remote Desktop User, Remote Desktop User Group, supported, Vista Home, Windows 7 Home, Windows XP, Windows Xp Home
