Hi Mwalimu,
I've been using the Rockton GP Toolbox for many years, but honestly could never use the scheduled timeout function since it was introduced... it never works. So unless I'm missing something essential that I don't understand, or it is not very clear in the GUI, I've always used the direct lockout function.. and put 'sa' and my account on the excluded list.. This has always worked for me.
But open a ticket at Rockton, they should help you with this.
