Mysqldump on windows client works but in bat file doesn't

[Stephen Neff]

Hello, I run the command below in my Windows 7 Enterprise from a cmd environment on my local client and it works. I made a BAT file and when I execute on my local client it fails with
mysqldump: Got error: 1045: Access denied for user 'xxxxxxx'@'ip address'
(using password: YES) when trying to connect

I am stumped. Why would the command fail in a bat file?

"C:\Program Files\MySQL\MySQL Workbench 6.3 CE\mysqldump.exe" --databases mydabase --result-file="C:\xxxx\xxx\xxxx\xxxxx\GOES\MYSQL\MySql\backup\databases.%TIMESTAMP%.sql" --user=xxxxxxx --password=xxxxxx -h xxxx.xxxxxx.us-east-1.rds.amazonaws.com -P3306
