Mapping a drive

Hi,
I’m trying to map a drive in dos on a win98 machine.An example of the command I’m using is c:>net use q:\\(server_name)\(directory_name)… The error that I get is as follows: “the specified drive letter or device is invalid.If you specified adrive letter check the last drive command in the config.sys file to make sure the drive letter is included..I know I could map this from My computer or explorer, But I’m trying to write a batch file. Any help would be appreciated. Thank’s in advance
