Need help with find and replace batch

[lkarelee]

I have seen a number of DOS batch scripts for find and replace - but none of them seem to work very well - and none will use a wildcard and recursive directories.

I need to replace our smtp server name in a bunch of batch files in subdirectories from 'ctmwebappp' to a fully qualified name like 'ctmwebappp.city.austin'

does anyone have a batch file that will do this using a wildcard?
