a script is the same thing that a batch file, like autoexec.bat on a windows 9X
an example
net use H: \\server1\EGBA
net use I: \\server1\GRAFICA
net use J: \\server1\logs
net use K: \\server2\logs
net use L: \\server1\admin$\repair
net use M: \\server2\admin$\repair
ntbackup backup H: /v /t normal
ntbackup backup d:\correspondencias /v /t normal /a
ntbackup backup I: /v /t normal /a
ntbackup backup d:\Basedado_Producao\I-One /v /t normal /a
ntbackup backup d:\Basedado_Producao\backup /v /t normal /a
ntbackup backup d:\Fonte_Producao /v /t normal /a
ntbackup backup d:\Executavel_Producao /v /t normal /a
ntbackup backup C:\WINNT\system32\Repl\Import\Scripts /v /t normal /a
ntbackup backup J: /v /t normal /a
ntbackup backup e:\logs /v /t normal /a
ntbackup backup K: /v /t normal /a
ntbackup backup L: /v /t normal /a
ntbackup backup c:\winnt\repair /v /t normal /a
ntbackup backup M: /v /t normal /a
this script make backup
you save at \winnt\system32\repl\import\Scripts, named as file.cmd
this is the path of the NETLOGON sharing
put the file name on your user proprieties on the user manager in perfil/logon script (may be a diferente name, i am usin a portuguese version trying to traduce)
i hope that it was helpfull
