Question : Access 2007 slow to link to Oracle database

Oh wisdomed Access Guru's on high,
I have some code which refreshes its tables links to an oracle database. For some reason it takes a very long time (3 to 5 minutes) to complete one or two connections and I'm wondering if anyone could take a look at my code to suggest a change or a tweak?

Many thanks

Ted

tthe script runs through AD, get all distribution groups and for each one create separate worksheet in excel and list their members.
