Mapping drives with network logon script

I'm an intern helping out with the City of San Jose. They are in the process of having users access applications over the network whether at work or at home with the Citrix metaframe server on a Windows 2000 machine. The problem is that the user needs to manually map a drive to the server to access the applications. IT wants to automate it with a script. How would a logon script with a command to map a drive look like. I would appreciate any help.
