[sukawindows7]

i have 2 desktop at my home, both using win 7 ultimate. both my desktop can ping each other, but why i cant use remote desktop ? it always said "An authentication error has occured. The local security authority cannot be contacted", what should i do to fix that error ?

note : i had configured all setting that required to use remote desktop

Hi sukawindows7,

Welcome to Seven Forums.

You will need to have the same user name/password on both computers in order to connect to each other.
You will also need to make sure 'Remote Connections' are enabled - http://www.sevenforums.com/tutorials/3922-remote-desktop-connection-rdc-network.html
