In the batch file that you've specified for the user's logon script that you use to map drives, specify the following command to execute a kix32 script.

%0\..\kix32 %0\..\script.kix

The %0\..\ part is a shortcut path to specify the netlogon share of the logon server being used. You must ensure that your logon servers are setup for replication so that they get the logon script and changes.
