Batch Script - Map Network Drive

Hello,

I have a batch script that among other things, maps a network drive using syntax similar to this:

Net use Z: \\192.168.200.10\dog$ /USER:dog-pc\cat C9d!42$%

When I execute the script, I get a "logon failure unknown username or password" error.

When I type the syntax (exactly the same as the batch script) into a command prompt, the command executes successfully and the shared folder is mapped.

What am I doing incorrectly that is preventing the batch script from working successfully?

Thanks
