User accounts in Access

Hi Sinead, thank you for your post, I notice that you have 2 posts on this problem, to my knowledge if you create a Security User Accounts on a database, if that database is located on a central computer ie server, then any person who wishes to use the database must be a member of one or more user groups, if they are not then they will be excluded from the database, I notice from your previous question that although this works from the computer on which the wizard was run when you access the database from another computer it is not in operation. Can I suggest that you check if the security file is on the server in the same folder as the database or on your own computer, if it is on the server, in the same folder, then I cannot see any reason why the file is not security protected. Please come back if you have more questions, best regards Pete.
