I've networked two Win 7 computers, A (tower desktop) and B (laptop). From B, I can create new folders and do anything I want on A, But on A I can't create new folders on B ("You need permission to perform this action"). This is preventing some needed software from running correctly. - From A looking at properties on B, and also on B looking at properties on A, Advanced Security Settings/Permissions shows all users having "Full control". - The Owner user is also included as a user in Advanced Security Settings/Permissions for both A looking at properties on B and B looking at properties on A. You can probably tell that I'm far from expert at networking. Any ideas for me to try?
