Is there anything I can call from the command line which will tell me if the currently logged in user has a limited account or is an admin?
With the default command tools (no third party downloads) you can use the net command.
%username% will have the username of the current logged on user, so I would use:
net user "%username%"
To display information about the current logged on user. The last section of this shows:
Local Group Memberships *Administrators *HelpLibraryUpdaters *HomeUsers Global Group memberships *None
Hope this helps
What I do most of the time is in the command prompt:
Then, I check in the user/admin groups
You can also check with the PSTools. There is a lot you can do remotely within a domain with this!
