If you try to run batch files (.bat or .cmd) from the network share on a Windows Server 2003 you get an “Open file – Security warning” -dialog where you must confirm that you allow the execution of the unsigned file. Basically this prevents scheduled scripts to run on the system.
If you are absolutely sure you want to allow the execution without confirmation, you can add the server which shares the executable file(s) in the Internet Explorer’s Local Intranet Zone. The systax is file://servername not http://servername. Note that this action compromises the system security.
