ODBC connection - permissions

[Rob]

I am doing the following in order to give some users access to selected
tables via MS-Access...

Create a Windows Security group in Windows called "ABC:"

Create a Windows authenticated SQL user called "ABC"

Assign individual users to the "ABC" group

Assign Select permissions on the 3 tables for user "ABC"

This works with one exception, I want to exclude the Schema and system
table....

Anyone know how to accomplish this ?
