Autocad folder/extensions exception

Hi,

I recently installed ADNM with about 30 managed clients, it works well.

But, I want to ignore some extensions to Autocad can work faster on 2-3 computers. How can I do that if I have managed client installed ?
Is it easier to make exception to the Autodesk folder or ignore dxf, ipt, idw, iam,… extensions ?

Regards
Melo
