Logon Scripts and AD 2008r2

I just migrated an old 2000 AD to 2008r2 and it turns out there was a logon script which mapped a bunch of drives and loaded explorer automatically pointing to the company intranet. Users authenticating on the new 2008dc are not getting drives mapped. Eventually I will handle this using GPO but for the time being I would simply like to re-enable the logon script. I notice each user has logon.bat associated with their account, where is this on the 2000 DC and where do I put it on the 2008 DC?

Thanks!
