help in scripting

[mjos]

Hi,
I need help in running a script which will map a NAS drive on the windows server on z: drive using a particular user account.
The issue is we are running Data Protector backups on the server & the NAS drive is mapped on z: drive using xyz user account. But when the user logs account the z: drive gets disconnected. So when backups run on the system, the scirpt will run first which will map the z: drive using that user & could take the backups.
Please help.
