When a Win9x computer logs on to the Domain , it temporary map's the last available drive letter (z in your case) to the netlogon share of the authenticating domain controller.

So when you try to map a share to z: in your logon script you get an error because z: is currently mapped to the netlogon share.

your solutions are,

1. use a different drive letter
2. Place a "net use z: \\server\share" in the runonce reg key (this will be executed after the users has authenticated to the Domain and the z: is no longer mapped)
